Be sure to read this because I changed some things!!!!

First, you need War of the Worlds and I want you to use the DTS track.

Second...We are using MULTIPLE timestamps, so just do 1 measurement at your normal listening volume (Speakers off though if you can)

Exact TimeStamp and Quick Description.

**21:12 to 21:15 Alien Pound Under Earth
**21:43 to 21:50 Grounding Turning and shaking
**23:11 Ground Implodes down
**23:35 Tripod first puts foot out
**23:46 Tripod Smashes the Car with its foot
**26:22 First Heat Ray
**27:19 Massive Heat Ray blows up building
**31:48 to 31:52 Tanker Explosion
**59:14 Ferry---First Foot Stomp
**59:18 Ferry---Second Foot Stomp
**59:20 Alien "sound" tone (Initial Freq)
**59:24 Alien 'sound" tone (LOWER Freq)
**1:10:09 Fireball Explosion/Alien Appears
**1:45:13 Low Sweep when Alien Crashes to the Ground


____________________________________________________________
Some things I learned to be sure of when using the SPL meter.
1. Use C-weighting FAST for this peak test
2. Use the MAX button if you have a digital Meter
____________________________________________________________

I'm curious about a few things.

1. Room size cubic feet
2. What subwoofer set up are you running?
3. What setting of Master Volume and what do you have your sub dialed in at?
****Note....when running this test turn off main speakers if possible so you are just measuring the subwoofer output

and finally the timestamps and scores.

JUST COPY AND PAST MY INFORMATION AND REPLACE IT WITH YOURS SO WE CAN ALL USE THE SAME EXACT FORMAT!!!! :)

I picked these ones out because to me they were the combination of the DEEPEST and Most powerful scenes in the movie. The whole movie is a feast, so I tried to pick out the best for us to look at :)

WOW the whole night passed and not one post. I thought this would be the granddaddy of them all since I gave 12 exact timestamps for people to easily measure their peak response :)

I was busy watching movies. When I get some time I will run through them.

WOW the whole night passed and not one post. I thought this would be the granddaddy of them all since I gave 12 exact timestamps for people to easily measure their peak response :)not everyone would be able to test even a few of the scenes, especially at night, without undue risk of shackles from the local authorities...these scenes play at and above 120 dB on the loudest systems and unless one has a dedicated and soundproofed theater, no one in the entire house would go undisturbed by these "spirited" decibel levels...just an observation... ;)

Ya....but what fun is owning a Corvette Z06 if you always drive the speed limit :D


The testing really only takes 10-15mins to conduct, if people can find the time and can do it without pissing EVERYONE off, then cool.

If not, then thats ok too :)

Don't worry, I plan on doing some tests with my old sub (SVS PB12-ISD) and my two new babies which should arrive tomorrow (2 20-39 PC+'s) So I'll probably do a before and after. And I have to two setups that I want to try with the new ones so I may have 3 sets of numbers for you.

WOW SWEET.

Dual 20-39+ should give you some VERY VERY impressive numbers! I almost went that route, but I'm going dual 16-46+. (Only have a single for now until I save up some more cash)

Are you planing on locating them in the same corner?? +6 boost in headroom..

We'll take all the numbers we can get....the more information the better for us and for you too!!! And for those new babies you won't find a more powerful cluster of scenes in one movie to demo!! :)

I bet you will be close to pushing 115-120db on some of these scenes if your room is not TOO big... :) (I'm jealous already)

I don't know how useful this information will be for comparison, without a baseline for comparison. However, it looks fun, so maybe I will try it with my Sony 12" SAW-M40 (remember that one?) for a laugh.

I'm sure it will lay waste to all the SVS's around here. LOL.

I am anxiously awaiting these subs as they are "out for delivery". I got the day off so I hope they come eary so I can put in some good testing with them. The two locations I have staked out for these two bad boys is: 1. Colocating them in the left corner where I have my current sub. And 2. Putting each in between each of my front speakers. I want to play around with each setting and see which one I'll like the most. I hope to have a report back sometime today and at the very latest tomorrow.

If you look at the other threads like this one you will see that everyone finds a starting point and increases their MV incrementally to try to find the compression point....the point where you are getting the most out of your subwoofer.

For this particular thread I figured just to post the normal listening volume numbers, but everyone knows if they want to post MORE readings than just that we will welcome it with open arms and use the data you provide to give feedback about performance and whether you have more room to play or if you are at the compression point.

And hey, we are not knockin your Sony, it is more than welcome to play with WOTW and you never know, you might surprise yourself, or you might learn that you have to calibrate it differently... :D

Well my new subs are here. But before I get to the good stuff I went ahead and tested my old sub so I could have something to compare it to. I added an extra time stamp or two and just corrected ones that you had listed. Well here goes:
21:12-21:15 Alien Pound Under Earth-98db
21:43 to 21:50 Grounding Turning and shaking-101db
23:11 Ground Implodes down-101db
23:35 Tripod Arises from ground-102db
23:46 Tripod Smashes the Car with its foot-102db
26:22 First Heat Beam-103db
27:19 Massive Heat Ray blows up building-102db
31:48 to 31:52 Tanker Explosion-104db
59:14 Ferry---First Foot Stomp-98db
59:18 Ferry---Second Foot Stomp-96db
59:20 Alien "sound" tone (Initial Freq)-I only took highest reading from this spot-104db
1:10:09 Fireball Explosion/Alien Appears-101db
1:45:13 Low Sweep when Alien Crashes to the Ground-108db

This is with a PB12-ISD (with old driver) Master volume at -12 and sub running at 78db or +3 hot. All numbers are uncorrected. These tests were conducted with an analog Radio Shack meter running C-Weighted and fast. Tests were done with speakers all ON because I don't know if it's possible to do the tests with speakers off on my receiver (Yamaha RX-V 2500) Room size is 3000cu/ft.

Hope to update this in an hour or two with results from the 1st location!

I cannot believe you didn't measure this one. That first foot that comes out was so powerful on my system! I know this is the exact time stamp---23:25 Tripod first puts foot out


I'm going to go back and add these ones in too and test them on mine for more data! Thanks
26:22 First Heat Beam
21:12-21:15 Alien Pound Under Earth


Another thing...you said your sub is 78db.....I'm assuming uncorrected.
So really 78db on the meter is really like 81db once you add the correction factor in, which would mean that your sub is actually +6db hot and not 3...

Sorry about that. So yeah +6 hot is correct. Well here is a quick rundown of my corner numbers. I did them quick but did test phase/calibrate, albeit quickly so I could come up with some numbers. Here's what I got:

21:12-21:15 Alien Pound Under Earth-98db (101db)
21:43 to 21:50 Grounding Turning and shaking-101db (104db)
23:11 Ground Implodes down-101db (108db)
23:35 Tripod Arises from ground-102db (109db)
23:46 Tripod Smashes the Car with its foot-102db (108db)
26:22 First Heat Beam-103db (109db)
27:19 Massive Heat Ray blows up building-102db (108db)
31:48 to 31:52 Tanker Explosion-104db (109db)
59:14 Ferry---First Foot Stomp-98db (100db)
59:18 Ferry---Second Foot Stomp-96db (101db)
59:20 Alien "sound" tone (Initial Freq)-I only took highest reading from this spot-104db (108db)
1:10:09 Fireball Explosion/Alien Appears-101db (105db)
1:45:13 Low Sweep when Alien Crashes to the Ground-108db (109db)

I placed both subs right next to eachother in the corner. I did not move them once I started testing to tweak for location. Well I'm gonna go try my other location out to see what I can get. Be back later.

Is the 2nd number the NEW SCORE in (***) with the Dual 20-39+s???


Did you use master volume -12db again for the test?

Where are the dual subs calibrated at? 78db uncorrected again??

Yes I tried to use all the same settings as I used before to make it as similiar a test as possible.

Well looks like good results going from the PB-12 to the Dual 20-39+s right from the start....talking anywhere from 1db to a massive 7db gain in output!

And thats right after setting them up and quickly running the tests. I'm sure you can even get more out of them once you find the sweet spot for your room and really dial them in perfectly. I'm excited for you and I'll update any numbers you get for the duals!! Good luck!!

Movies2090 I added those 2 extra scenes to the list and tested them myself.

The first 21:12-21:15 wasn't that powerful to me...but I added it anyways :)

I hope more people do this too!

Well I'm back with my final set of numbers. Bgillyjcu, the exact timestamp of the Tripods first leg coming out is 23:35 like I've indicated, not 23:25. Trust me on this, I've watched that scene about 25 times today. The 3rd set of numbers is with the subs separated in between each speaker. Not as good as the corner, but man does it look a lot better and a lot cooler.

21:12-21:15 Alien Pound Under Earth-98db (101db) (96db)
21:43 to 21:50 Grounding Turning and shaking-101db (104db) (102db)
23:11 Ground Implodes down-101db (108db) (102db)
23:35 Tripod Arises from ground-102db (109db) (104db)
23:46 Tripod Smashes the Car with its foot-102db (108db) (103db)
26:22 First Heat Beam-103db (109db) (104db)
27:19 Massive Heat Ray blows up building-102db (108db) (104db)
31:48 to 31:52 Tanker Explosion-104db (109db) (104db)
59:14 Ferry---First Foot Stomp-98db (100db) (97db)
59:18 Ferry---Second Foot Stomp-96db (101db) (97db)
59:20 Alien "sound" tone (Initial Freq)-I only took highest reading from this spot-104db (108db) (104db)
1:10:09 Fireball Explosion/Alien Appears-101db (105db) (101db)
1:45:13 Low Sweep when Alien Crashes to the Ground-108db (109db) (107db)

Well the looks are all good and dandy but can you really afford to move it from the corner considering that the 3rd set of numbers is not really any better than the SINGLE PB-12ISD???

I know if it were me it would be corner all the way!!

And you are right about the timestamp error....just a typing error on my part and I'll adjust it right now!!!!

Brad,

All that work down the toilet.... Just kidding. I experimented with moving it into that deep open corner on the other side of where it was, and it killed the bass. I then said, f the rest of my buddies and put it behind my couch. The bass was the same, at least by ear in the rest of the room. But, I benefit the most in my position. It is awesome behind the couch.

when you inviting em over?

Last week I did a quick and dirty calibration using my receivers test tones & a radio shack digital spl meter ,but Ill tell you what it worked wonders compared to no calibration at all! What I basically found out is that my sub was WAY to hot, everything sounds much more balanced now.

So you are going to use the behind the couch position or back to under the stairs?

Well I do have next week off of work, but I'll only be in town Monday-Wednesday (probably heading out of town Wednesday evening). What days this weekend or next week are good for you???

What I think you should do is actually buy a digital SPL meter like I had for $45 and I'll teach you how to really use it. you could bring it with up up here and you can practice. That way you can play even more freely and really test to see what kind of numbers you are getting. I can even burn you that same test disc I brought with me so you can do exactly what we did.

PS....after going to your place I was inspired to find the best best best palce in my room so I went on a sub moving missing. It turns out that the best place is with it HIDDEN behind my 55inch sony. (This was not an option with the PB-12NSD due to size, and I never considered it initally because I was a ilttle scared about putting this earthshaking monster behind all of my equipment. But it turns out everything works fine, no effect on the TV at all no matter what volume level.

So now you cannot even see the sub and bass just POUNDS OUT at even higher SPL numbers than ever before with the sub calibrated EXACTLY the same. I'm talking a 3db increase in ALL FREQuNCIES, which is amazing! You walk into my room and all you see it the mains and center....then WATCH OUT :D


ps.........anyone else in the Cleveland Area who wants a demo I'd be open for another 1-2 people in addition to Chris and myself....(as long as you are not an ax murderer or anything like that!!!)

Kramskoi,

Great looking TC Sounds army of thunder! Do I see triple TC-3000 15" woofers!

I am looking to build an opposed driver sub also,the best solution to cancel any sub vibration at very high SPL.

You have a PM

Thanks

Updated and might I add those numbers are just plain SICK! :D

I'd like to hear that if I lived in South Louisiana! Hell the people in Texas can probably hear it...LOL

Thanksyes, it is now three of them...i may build a second 2x15 in the future, for symmetry if nothing else (beside x headroom)...still waiting on the 4100-NEO to be released...then we'll see how things stand. ;)

the sub might like to move but at over 200lbs...? ain't gonna happen... :D

Hey Brad,
I just tried out Flight of the Phoenix, plane crash and it registered 112dB uncorrected in my large room with dual JL f113s. Not worth claiming bragging rights in terms of SPL, but it sure sounded "IIIIINnnnnnnnnCredible". It was somewhere around 15 minutes.
Knowing you and what you crave for, if this movie is something that you have not tried out with your awesome cylinder, I recommend this.
Check it out dude! I won't disappoint you. YOu know that right?

Cool thanks bro. I'll start searching Ebay and Amazon used to try to pick up a cheap copy. I'm always on the lookout for the top notch bass movies :D

I will second that suggestion. BG, you will probably want to use it for one of your tests. That's one of the best for bass. It also is not a terrible movie either.

Also for testing purposes, "The Haunting" if you don't already have it.

Im having a heck of a time finding the DTS version of The Haunting but I agree the movie has tons of bass.

Flight of the Phoenix (http://www.avsforum.com/avs-vb/showthread.php?p=10157182&&#post10157182)

If you go to HALF.com

Do a search for THE HAUNTING.

Click on the "Movie Search results" to view them all.

The 4th one down on the list should show a picture of the DTS version. This is where I got mine and it works flawlessly!

I would have posted the link but it won't let me....

Hope this helps people get the DTS version since it is pretty rare!!!



And I think I'll use the Haunting DTS next.

I'll look into buying the Flight of the Phoenix next and use it for testing down the line :) Trust me there are a lot more movies I want to do this testing with :D

I just printed out your list. I will try it out soon. My body will feel like I was hit with a bat when I am done. This should be fun. The haunting should do well also, I would inlcude jurassic park 3(DTS) as well. Heck, anything dts will be awesome.

MK Jurassic Park 3 the dino fight will be one hell of a test I agree!!!

I plan on using:
The Haunting DTS
Emily Rose
Jurassic Park I, II and III all DTS
Master and Commander DTS
Lord of the Rings all Three DTS
U571 DTS
Cars
Incredibles
We Were Soldiers

Thats just to name a few :D

I know I just said the Haunting next....but I might wait on that a bit so people can buy it from the information I just gave...

I'm not going to start up a new list just yet because I think people are still catching up on PULSE and I'd like A LOT more input in the new WOTW test thread...


and JAI...don't be shy about the f113 numbers! I'd still like to see what Dual F113's can do in your setting. Even if they are not insane in the SPL department, we are taking into account room size which plays a major role.

Remember this is not a competition, rather, something for us to use to test our subwoofers and talk about performance :D

If you go to HALF.com

Do a search for THE HAUNTING.

Click on the "Movie Search results" to view them all.

The 4th one down on the list should show a picture of the DTS version. This is where I got mine and it works flawlessly!

I would have posted the link but it won't let me....

Hope this helps people get the DTS version since it is pretty rare!!!


Thanks I was able to order a copy using that info :)

There's only 2 listings remaining for anyone else that might want it!

Glad to hear the information worked!

I'm always a little cautious when buying used, but I've managed to find a few rare DTS DVD's using half.com

Thats where I found Jurassic Park DTS (the good corrected version)

What do you mean corrected version?

That is some great nimbers you are getting Kramskoi! Your subs are stomping a mudhole in many commercial subs! Well your project inspired me enough to build my own dual TC-3000 15" sealed monster.

What do you mean corrected version?


Well the Original JP DTS had a bad LFE recording.

I had a major discussion post over in the DVD forum about it.

It really makes a HUGE difference.

Summary from the other thread to help you figure out if you have a defective one...


"You might have the defective DTS edition, the one that says D2R1 in the inside hub around the clear circle. If the tech grid on the back of the case/box is in black - i.e., the part that says what language, aspect ratio, etc., the film is - it's the first DTS edition, the one that is flawed. The corrected edition says D2R2 and has a red tech grid. Later issuances of the corrected one, however, have a different numbering in the holographic numbers around the clear circle/hub. JP was the first theatrical DTS movie, and the DTS DVD is supposed to sound pretty great - assuming you don't have the defective version. "


The TECH RING is really the easy way to see. Black means bad version and Red means good.

Trust me the difference is clear to the ear. The foot stomps of the T-Rex shake the hell out of you on the Good DTS version...(People with the bad version say its not any better than the DD version)

When I listened to Chris Carzoo's DD version I couldn't believe the lack of bass from T-Rex compared to my DTS version.....in this case the DTS version was clearly better!!


Also if you have a defective version Universal will send you a fixed one for free.

I got this email from them a couple months ago when I was looking into the issue...

Half.com lists a bunch of DTS versions for sale. Even if you ordered it and got the bad version, you could send it to Universal and they'll get you the corrected one for free. A couple people from the forum have done it and have confirmed that Universal did indeed send them back a corrected version....I think it did take close to the 6 weeks to get it though.

Flight of the Phoenix (http://www.avsforum.com/avs-vb/showthread.php?p=10157182&&#post10157182)


Just ordered it from Half.com :)

Those charts look fun....I like the subsonic information along with the strong 20hz area content. Plus I hear the surround effects are pretty kick ass. Plus for only $4.00 I couldn't pass it up :D

Not shy Brad, these things rock! One of the best sounds I have ever heard.
BTW, the measurments were with Avia Calibration, reference being 75dB. I was playing at reference level and subs were not calibrated hot (I usually used to have it calibrated +3dB). The f113s blended very well with the mains.
It was deadly loud. Anything louder, I was worried about hearing damage and potentially upset neighbors. I can do something like this maybe once or twice a week at sane hours.

Well I hope when you have time and are able to do the tests that you will record and share your numbers for this test :D

Thanks Bro!!

I have a bad copy of JP. I was never impressed with the bass so I always use JP3 for demo's. That will expain it. Looks like I will be waiting 6 weeks. Any info to send? Thanks

Thanks, I will do this ASAP. This weekend I will try to run the rest of WOTW.

Here are my test results.
MKtheater
1. 2300cuft (sealed, insulated and treated)
2. Dual 18 inch horns
3. Master Volume 0 db Sub calibrated to 75db on SPL meter (uncorrected)

116 db**21:12 to 21:15 Alien Pound Under Earth
121 db**21:43 to 21:50 Grounding Turning and shaking
122 db**23:11 Ground Implodes down
125 db**23:35 Tripod first puts foot out
125 db**23:46 Tripod Smashes the Car with its foot
121 db**26:22 First Heat Ray
123 db**27:19 Massive Heat Ray blows up building
123 db**31:48 to 31:52 Tanker Explosion
117 db**59:14 Ferry---First Foot Stomp
117 db**59:18 Ferry---Second Foot Stomp
119 db**59:20 Alien "sound" tone (Initial Freq)
116 db**59:24 Alien 'sound" tone (LOWER Freq)
120 db**1:10:09 Fireball Explosion/Alien Appears
123 db**1:45:13 Low Sweep when Alien Crashes to the Ground

Right before the fire ball explosion there was also a 122 db's explosion.

what was the time stamp when the machine stands up for the first time, when there is an arial shot? It sounds like there are two falls very close together on my crappy sony 8 inch that came with a shelf system.

not everyone would be able to test even a few of the scenes, especially at night, without undue risk of shackles from the local authorities...these scenes play at and above 120 dB on the loudest systems and unless one has a dedicated and soundproofed theater, no one in the entire house would go undisturbed by these "spirited" decibel levels...just an observation... ;)


WOW man 120+db's. Reminds me of my car audio days...LOL.

MK...

Those Horns speakers by the numbers look to be the real deal!

125 db**23:35 Tripod first puts foot out

I know this scene for me is a real shake the room and punch you in the chest scene and at 110db it is very powerful......now at your 125db that has to be earth moving!!!

It hits so fast and hard, then it is gone. On most movies it seems that it does not shake the walls because it is gone so fast. It does it so fast. With WOTW, because it has so much hard hitting bass right after one another it wakes my subs up. The difference in sound quality is noticed by everyone. So far only one person prefers the SVS. When I was switching I was not looking for more bass, just faster. I had no idea that these would be this powerful, especially down low. Remember this, My listening position is 8 feet away, but I get around the same numbers from 20 feet away. It fills the whole room, there is no escaping. Anytime you are around the utica are in central NY let me know. I would love to show guys(that are like me) these things. No one around here is into home theater like me. Most of the guys that have theaters go to the local dealer and just get their best gear and have no idea what they are getting. I kind of went crazy with this hobby but that is part of the fun. I have been thru over 15 peamps and amps, over 8 sets of 5.0 speakers and several subwoofers. I have owned outlaw to Meridian 861. Mostly 5.1 stuff.

You wouldnt happen to have any pics of these horns? To be honest im not even sure what a 'horn' type subwoofer looks like or what makes them different lol.

www.madisonamps.com look for their only horn sub in the pro audio section. The logo is much smaller and not as white as in their website. You really can't see it that good in person. The con to this sub is the size.

Ahh pro audio sub.. Crazy, what kind of amp are you using to power it? I see they make a 21" version as well.. I couldn't imagine that.

I use a sampson s-2000. To really exlplore the limits of the subs I would need another and run them in bridged mode for 2000 watts per channel. Most pro audio subs do not hit very low so I am told. This one has past all my low frequency movies so far. It played that pulse scene at reference @ 110 db's. I ran the gain up just to see if they would compress and no, it just gave me more spl. I can't imagine the size of the 21 inch. I don't think that is made as a horn. BTW that scene is a 16-18 hz pulse. I know there is a severe drop off at 15 hz, probably down 20 db's. I think the best thing about them is the sound. It reminds me of the cine capri cineplex in AZ. That screenis 29 feet by 79 feet. The sound is top notch and my base sounds and feels just like it, in fact the only difference is that mine hit much harder. My room is 21 x 15 with low ceilings. It fills the whole room with the same spl.

Update guys, the one friend who liked my SVS better finally sat down today to listen to a scene at reference levels. His words were holy _____. Now everyone likes the bass better. Another thing to note these subs did not dig as deep until I played about 5-10 demos and all of a sudden it started to loosen up and dig deep.

Even better that they are giving you more performance the more you use them!

I looked at the website as well, and they are some big ass speakers for sure! :D

The website does not do it justice. They are bigger than they look. It is because of their depth. really deep. Almost as deep as they are tall. They are heavier than posted. fedex weighed them together at 350 pounds and they only had some minor cardboard surrounding them. Thank god for the wheels and 3 handles. I did pick one up and sat it on top of another just to see what it would like like in one corner.

Hey James,
When it comes to SPL, your subs rule. The price is also very very reasonable.
A couple of questions.
How did you find these? They are not talked about a lot, here in the forums.
Secondly, I am really curious about the frequency response. If there is any way you can measure this, it will be invaluable information. If you don't have the necessary equipment for measuring, it is very easy to setup. I can help you find everything you need to measure this. The cost also will not be that much.

From your description, the sound quality also appears to be very good. If it indeed does not roll-off earlier than 20Hz, in room, this sub of yours sure deserves a lot more attention here.
Regards,
-Jai

Well juding by what he said about the PULSE scene he tested and what we know about the frequencies in that scene, I'd think the drop off for his subs is probably at the 15-16hz point...

MK do you think that is a good guess??

After talking with you about quality of horns and sealed cabinets I just had to try a horn cabinet. My goal was to find a horn sub that actually had it spec'd to 20 hz. When I ran my SVS in different tunes there was not much difference. I know it is tuned lower and can extend lower but in the real world of watching a movie you do not miss much of the extension. I did a search on the web and the first subs I came across were bassmax subs and danley. I did not want to spend that much so it left me with bassmaxx. Then out of pure luck I found Madison. I read a couple of reviews but they were based on guitar amps. For the price I had to try them. Heck with my amp used they were cheaper than my SVS new. I don't have any equipment to measure. I do have the test tone cd's and I am down about 20-25 db's from 15 hz and below which means I can still hit 100db's at 15 hz. During the 10-19 hz test tone it played very strong towards the end, almost as strong as the 20-29hz tone. When I purchased these I was hoping to get reference levels at 20 hz with improved sound quality. I am getting reference levels at 16 hz and well over reference at 20 and above with much improved speed and reaction time(is their such a thing). The subs will hit fast and then dissapear just as fast which allows me to hear more notes that were drowned out before because the big spl did not decay yet. An example is with king kong hd when he lands to protect the girl from the final t-rex. When he lands the SVS made a very loud thud with the wall shake afterwards. With the new subs I hear and feal 2 thuds with little wall shake. It suprised me because the thud is more powerful and 2 of them. The problem with owning these would be size and looks. They are black carpet(which fits nicely in my dark dedicated theater room). I can't imagine seeing these things in my family room. The footprint is very large.

Very glad to know I had some influence in your choice :). I think you found yourself a fantastic sub. In a dedicated HT room, I wouldn't worry about looks.

My front speakers are behind the screen with my subs in the back 2 corners. They are on the side and next to the back row of seats. Besides the great sound quality(IMO) that these provide it did something that I have been wanting to fix since I built the room. It evened out the bass with any seat. I used to hit 113 db's from the middle front seat with the SVS and 118 db's in the back middle. With these I hit 125+ from any seat. Exactly what I was looking for, reference level at any seat. That probably has to due with the 2 subs more than the type of sub.

I actually like the looks of the sub(in my theater), they are very solid especially considering the don't have an amp. I am also a sucker for piano gloss black but only when they are visible. My theater is a dedicated theater with a 135 inch anamorphic widescreen, it is for video. The purpose is not too look at the equipment. I have big sound for a big picture. I sit about 13-15 feet away from the screen, the back row is 20 feet away. I might move the front seats back a couple of feet, the screen is huge for that viewing distance, I love it.

I know exactly what you mean when you say it evened out the bass with any seat. I've had duals before but optimal placement not only smoothens the response in the primary LP but it smoothed things out in other secondary LPs too. Duals do give a larger sweet spot, at least in my room and now in yours. There is a lot of disagreement in this area too where people have had different outcomes with duals.
Also, in the lowest octave since I place them sufficiently close, I get the full +6dB gain due to acoustic coupling. This is important as it is at those 20 to 25Hz points that the JL starts compressing when driven to limits. Now I have more headroom.
Someday I am going to try your finding. How much did these cost shipped to the door for duals?

Placing my subs in the back corners I did get a +5 db's improvement, so that is great since they are 10 feet apart and I have no phase adjustments or anything. This is just calibrating them as raw as you get. I will pm you or email you the price.

Thanks. Knowing how keen you are about SQ especially how you appreciate the voicing of amps, I am sure your opinions on the SQ of these subs are "spot on".
Will look forward for your email.

what is your email? I tried calling you.

I sent a pm

I will call you back possibly today or tomorrow.
I just checked the specs and owners manual for the MAS 18-F (http://madisonamps.com/2007/products/specsheets/mas-18f.pdf). The FR looks very poor though. Maybe in your room, it gets a lower end boost and you are achieving a flatter FR.
I would measure the in-room FR. Your sub would be a good match for a small room but from the FR, I am not sure how good it would be in a large/leaky room.
I think you found the best matching sub for your room. One with an inherently flatter response, may sound bottom heavy in your room.
I recall you had a good experience with the Plus/2 tuned to 16Hz and that does not co-relate well with my theory here.

Yes, I looked at the graph as well and said oh well, I will give it a shot. In 16 hz tune it did sound tighter(a little). Most people EQ to flat. I don't use EQ, not yet anyway. After looking at many pieces of gear and specs, I have come to realize that listening is the ONLY way to see if someone likes something. If someone can't hear a difference then they can save alot of money. These subs are made for concerts and such. So big rooms should be no problem. Compared to anything I have owned or heard at dealers these are the best for my purposes. I know I am down probably 15 db's at 16-17 hz but it achieves such high db's in the other areas that I still can reach 110-115 db's without compression and 125db's without compression in the 20 hz and up range. These will not be for everyone as I stated before, but they are kicking the crap out of a svs PB2-Plus in any mode in detail, power, distortion, and speed. The Extension is about the same in the 20 hz tune.

Judging by the shape of that response curve in the picture, tuning looks to be at about 50 hz which is probably not that unusual in the pro sub world.

Completely agree that listening is the only way. Numbers only say so much and are just guidelines.

I know the subs start to drop off higher than normal but my spl is higher than normal as well, so even if it drops 20 db's I am still at reference levels at 16 hz or so. That is more than i can get from my SVS in my room. Running the test cd with the different frequencies the spl was within +/- 6 db's at any level except for under 16hz. So is my room making it flatter, I don't know. I am just telling you my results with certain movies. I did not think I would be able to feel the pulse wave like I did but I hit 115 db's with no problem. I think that says it is digging deeper than expected. Just look at my numbers for WOTW, it is doing something and with more speed.

Just look at my numbers for WOTW, it is doing something and with more speed.a good thing to do would be to plot manually, or through software, the FR at your primary LP...this will let you see what is happening below 20 Hz...

iirc, you need ~87 dB to make 16 Hz audible and running out at reference level (115 dB) you'd be around 100 dB or so...it would certainly add something to the experience...i think a combination of the horns' impedance coupling with the air and the higher pro sound F3/Fb is combining to give you good detail and theatrics at stupendous levels...it seems that your room is also helping negate, to a degree, the early rolloff of the horn...enjoy ;)

I am enjoying, it sounds like you know what you are talking about, You lost me there a little. I don't know all the technical stuff I just know that when I take out my spl meter I am getting really good numbers on low frequency scenes(pulse). The result is better than my SVS. I guess that is all that matters.

My Haunting DTS disc arrived today :)

Great dts disc for bass. It was one I used to use all the time for some demos.

So if the system can reproduce 16hz at 100db that would be considered reference level??

And 16hz being audible at 87db is a tough thing for probably anyone to actually hear.....chances are its the SHAKE that you are feeling rather than hearing.

bgillyjcu,
What is the frequency in that pulse scene again? Is it 16-18 or just 18? I want a scene that is 15-16 hz to see what my subs do. Some are saying that since they are pro subs they drop off early. If this is the case then they drop off slowly. I keep telling people I don't care for specs(the fr graph for my subs are not the best) but more for actual movie performance in my room. I feel like I am justifying my horn subs. Everyone who has heard them like them better than the SVS, and this is for only movies. I don't listen to much music.

whats the next movie your doing bgilly? My copy of wotw is still in the pawn shop.

has anyone been able to compare the audio/bass on WOTW DVD vs on HD feed (e.g. HBO)?...is there a significant difference due to the audio compression and how much compression is there in the HD channel feeds?

The DTS track on the DVD is way better than the HBO DD track. I've tried both.

MK, the Pulse scene is STRONGEST in the 17hz region based on the graph.

Up next.....Jurassic Park Trilogy Thread...coming this week...

well count me out on that one, no JP's in my collection.

Registered 117dB with dual JL f113s with eragon in my very large 7000 cu ft effective room at about 15 ft from sub. Highest in all the movies until now. I pushed my system to MV +5. Could have gone beyond but it was ear bleeding levels already. One of these days, I will push it beyond and I think I may reach 120dB.
It was scary loud. I think it was somewhere around 40 minute timestamp.

Man.. I watched The Haunting DTS with my nephew today and was amazed at the bass output throughout the movie ..by far the deepest / strongest bass ive experienced on my HSU 3.3 to date .. The part when she wakes up and says "Coming mother" then you hear a few thumps followed by REALLY LOUD thumps literally scared us both :eek:

"You might have the defective DTS edition, the one that says D2R1 in the inside hub around the clear circle. If the tech grid on the back of the case/box is in black - i.e., the part that says what language, aspect ratio, etc., the film is - it's the first DTS edition, the one that is flawed. The corrected edition says D2R2 and has a red tech grid. Later issuances of the corrected one, however, have a different numbering in the holographic numbers around the clear circle/hub. JP was the first theatrical DTS movie, and the DTS DVD is supposed to sound pretty great - assuming you don't have the defective version. "
.

Ugh my JP DTS disc arrived today (half.com) and its the D2R1 version.

Don't fret....you can send it to Universal and they will send you a corrected disc for FREE!

Yea , Guess I was just bummed out a bit lol , Ill send it off for a replacement soon. I was just testing it out and sure enough the DD track is a lot more powerful than the DTS track during Chapter 11 "Ripples in water" scene.

BUMP....can we get some new readings from members who own:

SVS Ultra 13's?
Conquest
Castle
Tower
MFW15

ect...

Hey Brad, How are you? I have not heard from you. I just built some eD sono's and let me tell you, nothing comes close as of yet. I mean in both sound quality and spl. I ran thru WOTW again and I pinned my spl meter on many occasions. It goes to 126 db's. So I will just say that I hit 126 db's(running 6 db's hot). When the cop says everyone back and then ground gets ripped apart I pinned it, when the ground implodes I pinned it, when the first foot came out I pinned it, the second stomp and car break it pinned, the laser strike pinned, the second laser strike it pinned, when the laser destroyed the lady in the car it pinned, when the car came crashing thru the window it pinned, and when Tom Cruise was running at the end it pinned. The whole scene was at 118db's and above. So if there were low frequencies I was at least 118 db's. My pants were flapping, my hair on my head and arms were standing up and the room was shaking alot(door handle fell off). If you have time and a little skill, DIY. I can't believe it, just awesome. Makes everything I have owned seem small potatoes.

WOW.....Clearly you have built something special. I am jealous!

Glad to hear from you. When anytime the subs hit very hard and max my SPL meter there is a gust of air that hits you and it feel like a wind tunnel. The bass is just so powerful and accurate. Size matters and my 8 inch port makes a huge difference.

Wow. That is pretty impressive. Everyone does that first part. But for me, the second attack, after he steals the mini van is very good as well. When the bridge blows up and the truck goes flying into to the house is where I get close to the max for me. I am sure you could pin in at that point as well. Congrats on building some serious bass machines. You should try that part as well.

So I guess you like them better than the 18" horn? Was the horn the ... MEPRO-18F. 800 watt Eminence Loaded18" Folded Horn. 4" Kapton voice coil, 109oz. magnet. 3/4" Birch Construction. Spray Coated. Made in the USA ...? Is this saying it comes with an 800watt amp or it can handle one? Thanks.

Those horns were beast. They provide more output from 50-100 hz(2 of them) than what I have right now. They can handle 800watts rms. They are passive subs. For midbass impact they are hard to beat for the price. They just drop off around 30 hz in my room but still provide excellent infrasonics. I just wanted to bump up the 20 hz and below. I could have kept the horns with these subs but I wanted the money. I get about 15 db's gain in my room down low so remember that.

So you measured your bass port? :eek:

I guess Port size matters to most people, especially if they have compensate for woofer size. :p

No, I did not measure, I just bought an 8 inch sonotube and cut it to 33 inches long to get the tune I wanted. I guess I am compensating for my 4 18 inch woofers;)

four 18 inch woofers! :eek: :D I hope you have a pic of that killer sub! :D

4 sonosubs, check out my sig

And this was done how? Some sort of new math they are teaching the kids these days:D

The DTS track on the DVD is way better than the HBO DD track. I've tried both.

Is the HBO DD track different than the DD track on the DVD? I don't have DTS decoding ability and I'm wondering how much LFE I'm missing with the DD tracks for this disc as well as others.

In my opinion, the LFE in the DTS version is simply mixed hotter but has no additional content.

And this was done how? Some sort of new math they are teaching the kids these days:D

OK, there was some measuring.

just messin:D. In your pictures they still look "unfinished". Are you going to put a cover on them? or just leave them as is.

They are hidden from view with the screen. I really don't have to put a cover on them. I have thought about it.

Yea. I guess not. If they are hidden, it really does not matter. But any way, getting this thread back on track. you have posted some serious numbers before. I have never experienced anything at that level. When Mark S. came out to setup my SubMersive1 he cranked up the system to where I was really scared. Also, I once heard a JM Labs Sub Utopia Be that was really getting loud. I am sure there were peaks well above 110+. I normally don't do that. I may hit peaks of 109 or a bit higher and that is plenty for my room.

I know what you mean. I really only run them at reference levels, mains to 105 db's, and lfe to 115 db's. The 2 combined for 120 db's. I run them hotter(6db's) just to see what they can do. It is scary. I keep thinking the windows are going to break upstairs. Also, the hardwood floors flexing in the room above really scares me. It lifts you up a bit.

Speaking of flexing, I saw the walls flex one time when I was in the room with the Utopia Be sub. It really freaked me out:eek:. I was told that the entire 22,000 sqft building was shaking. But, it was freakin' cool none the less. My room is to small for me to get to that level. But I have no doubt that it could be done.

LOL mate that the wavelength travailing upwards, mate get some double guzzled widows before all the putty starts falling out! :D

My last home the kitchen window rattled and buzzed around from 50Hz downwards it was worse when playing an 18Hz sine wave it was physical moving I could see the window at angle with the light on it, and I could see the refection on the window moving back and fourth.:D

I only noticed the living room and kitchen wall vibrate under the lower frequency when playing War of the Worlds (2005) this afternoon, I mean yesterday afternoon. If I had some kind of laser on wall I might see it fluctuate a little bit due to the wall moving.

I was playing the opening sequence along and the wall behind me while standing up with back to the wall and my hands I felt it move, its cavity wall and cavity walls will move. Well the molecules or is it atoms inside it are moving fast to create solid mass. LOL

I took some different waterfall readings rather then the direct link between each single channel to the computer; I decided to use a different approach.

Took this reading from the opening narration with the ECM8000 and MIC100

The pulse on the dramatic drum beat at 2m: 27s I can feel a nice sensational feeling in the sofa that fades away, and away as the camera moves into the shipping dock yard.

I neglected to take an SPL db reading but it was high over or near the 100dbc mark, because when I monitored other parts of the film LFE.1 only interacting with the fronts and surrounds it was well over 110dbc, too much!
