Identical L/C/R ... Why?

• How much do I have to spend on a AVR? Post 24

AVRs beyond extreme budget sound the same without EQ else they are broken!

Post 376 in this thread has pictures and parts list for assembling the eight sealed subwoofers - Bought four sealed 18" cabinets on a wild hare -...

Yes, my chairs also have subwoofers: (2019 addition) and Buttkickers (2021 addition).
The MB Quart subwoofers are BOSS inspired direct mount open air 12" MB Quart II subwoofers installed in Berkline Hometheater chairs with 20 Durometer Isolator feet to offer a little bouncer. (just slightly stiffer rubber than a gummybear). This allows for somewhat like nearfield 18" reference level tactile feel, direct to the chair, without any sound (open air subwoofer make very little sound), but with an accuracy of tactile feel that only subwoofer drivers allow. (bests Crowson, Buttkicker, Clark, Aura, in accuracy IMO) See posts starting at 2040 for more information.
Archaea's multi-purpose Home Theater room


Room Treatments:
CertainTeed Theater Black f ceiling tiles - NRC rating of .65 and 3% light reflectivity
9" R30 pink fluffy insulation in floor joists above tiles
Acoustic 3" wedge studio foam on front wall - NRC rating of .75
Acoustic 3.5" wave studio foam on side wall - unknown NRC? But working great! (since my seating is offset from the center of the room I could hear more reflection from the right wall when seated, after adding those vertical wave foam pieces, both sides sound very open!)
Walls painted Olympic One Black Magic matte paint.


Misc. Equipment:
Cooper B-line AV rack - (installed into wall on front left)
Panamax M5400-PM power conditioner (yes they work and are worthy of addition to your theater). They reduce line noise from the amps to the speakers, and help insure your expensive equipment isn't getting dirty power off the grid or home lines. It's a pretty clear difference plugged in or not in my space ---- NOT placebo!


Use:
I enjoy playing games, HTPC use, and watching movies or listening to music. I typically listen to music casually instead of critically. I like using Dolby Surround as the DSP for music. I don't wear the brand of audiophile, instead I'm an enthusiast who is willing to try new things to learn about the hobby. I'll call a spade a spade.
As a volume preference, I watch movies at about -12 dB with the bass ~9 dB hot. I like the bass hot by about 12-20dB for music listening.
I'll watch demo clips at reference with the subs still 9dB hot.


My Home Theater was reviewed in December 2021 by Youthman. Here is that video:

It was also featured in the July 2022 MidWest Audio Video Experience Conference (MWAVE). Here is that video:

Here is a video showcasing what my eight 18" subwoofers and tactile transducers setup can do when it's cranked up for fun.

Room Evolution

Ground Zero: - started with a finished basement in a 1985 built house we bought in 2014. Here's a real estate ad photo at the time we bought the house.

Version 1.0
2014 - (3) JTR 228HT, LCR (4) Mackie C200 surrounds, (2) Sony Spasato in-ceiling, and (2) JTR Captivator ported subwoofers in 7.2.2 configuration.
In this version I had (2) JTR Captivator Pros - these are incredible subs - I expect it took me six UM18-22 subs in sealed cabinets to match the pair of JTR Captivator Pros I had. However, 8 sealed UM18-22 got the nod.

Version 2.0
2015 - (11) Mackie C200 in 7.8.4. configuration and (8) UM18-22 sealed subwoofers - Version 2.0 configuration information starting around post 1378

Version 3.0 - 2019 - (13) JBL CBT70J-1 with DIY RGB 5050 LED Strips installed behind the tweeter array, and still the same (8) UM18-22 sealed subwoofers in a 9.8.4 configuration. Version 3.0 configuration information starting around post range 1870-1990 for obtaining, fixing crossover issues, installing RGB LED lighting, and installing speakers.

This one is at 5% on red only which is dark enough to use during movies with no negative impact to the image. (view front of room to back of room)

My biggest interest in the home theater hobby has been pursuit for quality subwoofers. I had some car audio experience in my highschool, college, and younger days, and I always appreciated great bass. It was the biggest draw to me towards home audio. I'll post my subwoofer experiences for the last decade or so here:

I currently have eight assemble it yourself, (AIY) subwoofers. I used the Dayton Audio UM18-22 18" driver with CNC and wood veneer covered cabinets built by a shop in Chicago. I'm using four Behringer iNuke DSP 6000 amps to power the subs. The sealed subwoofer project was chronicled here:
Bought four sealed 18" cabinets on a wild hare -...
You can see a unsmoothed frequency response capture of my system here. I'm reasonably flat to 7hz with my eight sealed subs. This is with no main speakers playing and just a capture of the subs alone using omnimic.

As to my past subwoofer ownership: (Newest to oldest)

• Eight, Ultimax UM18-22 subwoofers in 21" cubed wooden veneer boxes. This is the best subwoofer system I've owned - when taken as a whole system. Individually just a single sealed 18" subwoofer is not terribly exciting. However, when eight of them are combined, and some are nearfield, they deliver a remarkable presentation.
• Jamo 650 sub - (purchased 2012) discontinued price of $250. This Jamo is excellent for a smaller room full audible bandwith sub system (flat down to 20hz in room). Currently assigned duty in a bedroom system.
• Pioneer SW-8 = junk but still currently own for living room system (purchased in 2012)
• Captivator Pro pair (purchased mid 2011 - sold in 2014) Love these, simply excellent. I loved the wind effect these could generate - it enhanced movie watching!
• SVS PB13 Ultra pair (purchased mid 2011) (sold 2011 - I didn't like them too much for music, but they did great in home theater!)
• Yamaha CW218V (purchased mid 2011) (sold 2011 - loved for music - didn't dig deep enough for home theater)
• Jamo D7sub pair (purchased mid 2011) (sold 2012 - liked them quite a bit for $500 price - were fantastic for music with the right settings - THX Ultra II certified - overpriced MSRP - not very capable of high SPL)
• Infinity HPS-1000 pair (purchased 2003) (very nice subs IMO, the best Infinity has ever made according to my local authorized repair shop, one 15" driver with two passive 15" radiators and a 1000 watt amp - sold 2014)
• DIY subwoofer ottoman with four 15" MA car audio subwoofers (built in 2002 - sold 2012)
• JBL PSW-D115 - 15" home theater sub (purchased 1999 - sold?)
• AIWA HTIB sub = junk (bought in 1997 - sold 1999)
• Multiple iterations of car audio subs, some I used in theater (most of my car audio stuff was in my younger days - high school/college -- my favorite car audio drivers remain the Infinity Kappa Perfect drivers)

~ and probably more I'm forgetting.

and not so recently - - - scads of car audio subs --- up to some of the best types of subs like JL w7's and competition Orion drivers -- because I and many of my friends were into car audio.

My thoughts on the importance of subsonic ultra low frequencies?
Advice ; goal is 8-10hz flat at -15 reference
This opinion changes with the ability of tactile transducers, because you can absolutely feel the lowest frequencies with something like a Crowson, or a Buttkicker Advance, or a nearfield subwoofer. So the reference I link above applies to traditional far field sub placement.

I've heard lots of speakers --- too many to recount. I've visited over 100 AVSForum enthusiasts home theaters, and I've been to Axpona twice where you can hear hundreds of speakers in a weekend. I've heard speakers that cover the full gamut of price ranges; anything from $800,000 a pair to the cheapest Internet Direct huckleberries and DIY options touted heavily on this forum. Some of my favorites were not the ones that were most expensive. I think there are "Many roads to Rome" regarding choosing your personal favorite speaker, and I do not think there is a clear objectively best speaker that everyone will universally prefer in an A/B. That's been proven otherwise in several blind tests I've participated in. There are far too many variables to make such a declaration, including subjective personal preferences, familiarity, and biases. My opinion on speakers for the most part, just enjoy what you like and what sounds subjectively the best to you, and don't worry about what your buddy thinks. Currently I'm enjoying the CBT Line Arrays more than any other speaker I've ever owned, and have been fully satisfied for the last few years with them.

 

[Archaea]

Hey guys,

I've moved to a larger home, and the new basement space needs to be outfitted with my existing theater equipment. I'm looking for suggestions on the best way to go about this on a tighter budget than many of the dedicated spaces I see on these forums. I love many of the designs I see, but this won't really be a dedicated space. It will be a multipurpose space. Of all the theaters I've been to I think Craig John had some of the best acoustical treatments I've heard yet - at least to my ears. His theater concept was similar to my intent in that he had about half the basement as a multipurpose room with the screen up front on one side and a card table in back for multipurpose use. He said his theater was designed on a dead front/live back concept that is an older acoustical design concept, but I really liked the way it sounded for both movies and music. My room is basically a sandbox, so no option is really off the table. My wife gave me the go ahead to do most anything I want with it - as long as it is reasonably affordable. So I'd like to consider all suggestions.


Here is my previous home theater room so you can see what I'm used to:
http://s1191.photobucket.com/user/jvonengeln/library/Home%20Theatre%20Room%202011?sort=3&page=1

What I'm initially thinking is a 2:35:1 AT projector screen built into the storage room wall and using the storage area to easily house/baffle the speakers. I'd put the JTR 228HT front soundstage behind the AT projection screen.
I have six subwoofers. Two JTR Captivators and four 22" sealed cubes holding yet unchosen 18" drivers. One thing I really enjoy doing is hosting audio meets and demos for fellow enthusiasts. Ideally the AT screen will allow me to do blind comparisons of gear for friends and enthusiasts.

My seating area, for the front row is in the 12-13 foot range from the wall. I'm not sure if my room will support a second row or not in the current arrangement, based on the lower HVAC duct dropdown.
My ceiling height 89" and only 81" where the HVAC ducts hang down in the center for the room.

My room width is 218" wide
My room depth is 286" deep

My Projector is the inexpensive Epson 8350.
My screen is yet unchosen, but I'm considering Seymour XD, or UF, or open to other suggestions like Falcon or anything really at this point.
At some point I would like to purchase a new Panasonic or JVC projector for the automated zoom function with the 2:35:1 screen concept, but that's a future intent.
I'm playing with screen sizes using tape on the wall as a frame of reference. From my seating position about a 120" or 130" 16x9 screen is about as big as I can use in my room.
I may want to place the subs below the screen - so with a 89" height room, I'd need to keep the screen size limited to about 60" tall to both have room for the subs under the screen and keep my feet from barging onto the screen real estate when reclined in the Berkline recliners.

You can see my old home's multipurpose theater space in my signature. I do like dark walls, and dark ceiling to help with projector contrast. My new home is very much light controlled. There is only one window in the room and it can be tinted out as it is already just frosted cube glass and not useful for looking outside anyway.

I enjoy playing Xbox 360 games, PS3 games, PC games, and Internet browsing and such on my projector as well as watching movies or listening to music. It's probably a 50/50 split between game playing/PC use and movie watching or dedicated music use.


No more talk from me. I'll throw up some pictures and read some of the initial suggestions from you!


Please excuse the mess - we are still moving in and getting situated. Only 1 of the sealed 22" subwoofer cubes is up front, but I have three more. (4 total) I'm undecided if I would put the subs under screen, spaced around room, or behind AT screen. Future measurements will help with that decision, but I want to keep at least about 25" below the screen in case I decide to place the four sealed 22" cubes below the screen.


PICS here:
















black tape marks 16x9 with 60" height viewable.




black tape on outside marks full zoom size of James Bond Movie with 60" high 2:35:1




In my playing with this size, I almost feel like 2:35:1 content is borderline too large at this size, so I may have to size down the screen to 56" height and try again. My current 16x9 screen (seen along the wall in the pictures) is a DIY job made with JoAnn's black out cloth made for the old house. It is 106" diagonal or 52" height. I do not feel it is too big from 12' away - in fact it is just about right or maybe a couple inches smaller than my most ideal preference, but 60" may be a bit big - especailly in the 2:35:1 zoom picture to me... So maybe 56" high might be the next tape placement for the CIH screen that I try. Or I may just try moving my seats back a foot or two more. I thought I read that the ideal setting is keeping the prime money seat in a equalateral triangle with the left and right speaker. So if my seating is about 12 feet back from the screen, then ideally my screen should be about 12 feet wide (or a bit wider) in the 2:35:1 mode. I think I'd like to put my left and right speaker behind the AT screen if it is at all feasible - so that my entire front sound stage is behind the AT screen - but if that doesn't work I can just cover them with speaker cloth on the baffle wall and they could reside outside the image.

[Luke Kamp]

Are you going to use an anamorphic lens? If not and using the zoom method a 2.35:1 has 33% of the vertical resolution off screen and you have 1920 x 811 active pixels for your calcs above. Will be cool to see this come together. Like the new theater space and home.

 

[popalock]

This is a new perspective shot I haven't seen yet...




With a little work, you have the potential of having one of the most epic baffle walls...ever.

I probably won't consider an A lens unless I find some stellar deal on one. After some additional projector time spent I'm thinking of going a bit smaller (like you advised in person). Perhaps a 56" tall CIH image. Actually my old 16x9 106" DIY diagonal screen doesn't bug me when I put it up, so I may just got a smidge bigger in the 2:35:1 format. I put up a wanted add for a Panasonic 8000 projector so I can have the auto zoom/focus function. I bought some acoustic panels - OC 703, and rock wool stuff on craigslist. The cloth coverings were not to my taste, so I'll have to recover, but at least I have some absorption panels to play with.




Baffle wall....Baffle wall....


hmmm how to proceed....

https://www.google.com/search?q=baffle+wall&source=lnms&tbm=isch&sa=X&ei=14U9U6ahIMXN2wWN3IGgAw&sqi=2&ved=0CAcQ_AUoAg&biw=1264&bih=710#q=audio+baffle+wall&tbm=isch

 

[Conspiracy*]

Subbed. You've always given good info on audio, can't wait to see what you do with the new space.


Also...When I was last looking a Panny AE8000 could be had for under $2000 with specials direct from Panasonic.

 

[coolgeek]

If you're sitting at least 11-12 feet away, then I would recommend the XD. It's brighter than the Falcon by about 10-15% (when compared side to side), although the Falcon disappears at about 8 feet.


BTW: Are you going to build a riser? If so, how high do you want to build it? I too am now trying to figure out sceen height (so as not to see my feet when reclined), and also how high the second row's riser should be.

 

[Archaea]

Thanks for the info coolgeek.


The calculator in the second post of this thread has some tools that let you help determine seat heights - scroll to the bottom of the first tab.




I put my Epson 8350 and 106" diagonal 16x9 screen up on craigslist two days ago. A guy already contacted me and said he thinks he'll take the package - screen, projector, and mount, but wants to see them first. If it sells I'll probably either buy a JVC or Panasonic AE8000U (only options I'm aware of with autolens memory in the budget projector range) and get a 2:35:1 screen. I'm thinking about a CIH acoustic transparent screen with about 54" or 56" of height is going to be about right in my room from my seating space --- after playing around with a lot of different sizes (taping borders and watching movie clips) over the last couple weeks.

Subbed! The room has so many options. Can't wait to see what you do with it.

Thanks for the info coolgeek.


The calculator in the second post of this thread has some tools that let you help determine seat heights - scroll to the bottom of the first tab.

Ah, thanks.. will check out the calculator...


Can't wait to see what you end up doing with your basement! My house renovation have now taken close to 2 years and it's not even done yet.. and totally over budget...

I've been wondering which surround speakers I'm going to go with in this room. I'd like matching JTRs for all surround channels, (ideally I'd put 228HT everywhere) but I really can't afford to finish up my setup with JTR unfortunately, and I'm really just happy I was able to purchae the front sound stage of JTR equipment (three 228HT, and two Captivator subs). The surround 'quality' isn't as important to me as my front sound stage.


I currently have a set of Klipsh RS-3, but they fall behind the JTR 228HT quickly as the volume goes towards reference. So I'm wanting to explore options for six high sensitivity speakers to use as front wides, surround, and rear surround.


If eD was still around I'd probably pick up six of the eD cinema 6 speakers or something along those lines.


Recommendations?

Have you considered any of the SEOS offerings?

I thought someone talked about the pro jbls for surrounds with some of the jtr speakers. In fact the featured ht this month has them for surrounds I think.

First 2 things I'd look at, personally.

 

[Archaea]

Sold Epson 8350, 106" 16x9 screen, and Chief mount for $1150 on craigslist.



Purchased a Panasonic AE8000U for $1900 after rebate from B&H

Purchased a 144" diagonal 2.35:1 Jamestown AT screen with Seymour XD material for $400ish on classified. (new is $650ish)

Purchased a third Infinity Kappa Perfect 10.1 (still looking for one more) to make nearfield subwoofer transducers immediately behind my berklines. I really like the effect. It beats the buttkicker transducers hands down. eBay is running 25% off some of their subwoofer enclosures - spent a bit of time looking for a good pre-made match to stand up with a slant and aim into the rear of the berklines. I want to use sealed, because ported 10" enclosures are typically tuned way too high for my preferences in home theater. The Infinity Kappa Perfect 10.1 is a beefy driver, so it oughta handle sealed nearfield duty fine with some boost applied from my inuke DSP 3000. If this works out well I'll be selling the four LFE mini buttkicker transducers.



Need to purchase a projector mount for the AE8000U and I want a nice solid one.


I would like to purchase a set of matching surrounds. I've been watching ebay for some used JBL cinema stuff. I don't think most of the Klipsch stuff could keep pace with my JTR 228HT front soundstage.


I still need to figure out how to do front wall. Probably doing a baffle --- which type of wall cover is still to be determined. I'm going to try to go dead front, live rear model for my room.

I highly recommend the OmniMount 3N1-PJT.

[Archaea]

I'm going to try to stay away from any ball mount type projectors this time. I'm tired of them slowly moving with bass vibrations and requiring re-adjustment. I want one with set screws. Probably something like one of the chief mounts is my target.

My old mount has set screws. I will find it after work and send you some pics if you are interested. I still think the OmniMount works way better though.

 

[Archaea]

Bought four of these to house the four Infinity Kappa Perfect 10.1 Subwoofers

Will stand them up on end firing into the back of the Berkline chairs at an angle to introduce more tactile feedback into my chairs.


two subs will be powered on each channel of an iNuke DSP 3000. Dynamic boost will be used to boost the lower frequencies more at lower volumes.
