Gotcha. Now I'm picturing sitting in a 6000 cu ft room with my entire setup in a 1000 cu area and empty space all around. Lol.

In fact, given my front and rear boxes are setup with different response curves, I didn't notice my front stage was off until a familiar part of the song was a bit lacking in the mid-bass department. Other than that, I'd say my near field gives me 90% of my tactical feel...

Oh, and don't get me wrong... that 10% from my front stage is pretty intense. If I was to just play my front stage with no near field, that 10% would still be pretty impressive to some... <---Just basing that on the feedback I've received thus far from those that have demoed my space.

I'm in the same situation. My nearfield subs (FV15HPs) rule the tactile feeling and couch shake...particularly in the 12hz or so to 20hz if I had to guess. Above 20hz and ramping up to my crossover, I think the back subs and front subs slowly start to equally share the tactile 'punch/kick in the chest' feeling. However, the FTW21's provide a weight and heaviness throughout the band that the FV's don't provide nearly as well.

Meaning I required much less boost and power down low to reach lower in frequency. I have posted all my different rolloff profiles Of my drivers and my little guys were the best low frequency drivers of all! Not the most displacement but the best period! Now I have read good things about the Fi IB drivers and they seem to be much better than their other drivers but we will see. I know even if they rolloff more I will have plenty of displacement to boost them.

 

MK, what are the specs of those Fi drivers?

post #214 of 1882
Which ones? X-max 30mm.
post #215 of 1882
For those with AT screens. Are you counting your space behind your screens in size of your room?

I presume it makes sense to do so given the "acoustically transparent" nature of the screen. Just want to make sure I'm on the same page with everyone because I just finished framing one up this weekend.
post #216 of 1882
Yes, I did but with my new IB setup I am enclosing that area and sealing it off from the rest of the room. The screen will be in front of the new wall. Man, I am adding displacement and shrinking my room at the same time, I never even though about that until this thread. I had plenty before.

post #218 of 1882
I like this 'for fun' measurement of ULF capability. It's nice to put things in perspective and give some form of relative comparison - such as the output of some of the wild systems on AVS.


We recently moved into our new home, and as such I had to reconfigure everything in my setup. I am still weeks/months away from finishing, but I have had some fun in the meantime...

Subs I am currently using:

2 x LMS-U 18's sealed in 4cf each - powered with a clone FP14K (Thanks again MK)
2 x LMS-R 15"s dual opposed ~6cf - powered with an inuke 6000DSP

based on modeling the pair of 15's are very close to a single ultra, so I'll go with 3 DIY LMS-U as my 'si number'. Please correct me if I should use something else.

The current but temporary home for the system is in a 1500cf sealed office/room, which at 10Hz is 1500/5.7 so 263. It is pretty insane in there, even though I don't watch much due to the 42" tv. ULF is very apparent, much heavier and physical than my old room which was an L shaped mess of about 2000cf.

We are prepping and getting ready for the permanent room, a 3200cf area open to most of the basement and stairs. I will be using the LMS-U's or other sealed 18's nearfield, and adding another undetermined amount of sealed 18's until I'm either satisfied or my wife threatens to leave, with the dual opposed LMS-R's going into our living room. I guess I can add up some options using this ULF score, and at least have a good idea of the level of ULF output it will produce. I know it isn't entirely accurate, but it's a good place to start.

Assuming I have to live with my current setup in that large room for some time though, that makes my 10Hz score 561. Still pretty good I suppose.



Story time!

Earlier I said I had some fun - here is where it happened:


The week after we got our furniture delivered from the moving company (sidenote: it's stressful moving 2 beautifully finished Funk Audio 150lb boxes with lms-u's eek.gif) I decided I needed to test everything to ensure no damage, properly working etc. for claims purposes. The movers put all the (very heavy) subs and speakers in a small spare bedroom in the basement, even though we asked for it in the office area. Not a big deal, I'd just move it into the other room as I set it up. I decided to test everything in this room though, as it was all together already.

I unpacked the 3 subs and all the speakers, placing them around the room wherever they would fit. unpacked the Onkyo receiver and connected everything along with a 20" monitor. Everything looked good and worked fine, no issues at all cool.gif Big relief after the move.

Now the fun.

I decided to be an idiot with the wife gone for the day, so I hooked up the front three speakers and placed them in their approximate spot in the room. I made sure each sub amp had its own 20a line, and got out the mini dsp for some LMS-U protection. I put each LMS-U sub in a corner, and plopped a pillow on the dual opposed box and had a seat. Using my laptop I did some very quick and dirty eq, and watched some of my favorite scenes with ULF while pushing the volume up as high as I could tolerate. I almost got the clone to flash its clip light on some music, but couldn't quite do it - I was using ear plugs at this point. It wasn't even so much the volume of the sound that stopped me, as I was running the subs waaay hot, but the sheer pressure and physicality of it - especially anything ULF. Bass I love you was crazy. WotW was insane, FOTP too... F'n Irene was a blast. A scene from the Amazing Spiderman was almost nauseating, as it was only ULF eek.gif After that I was done, unhooked everything and started moving it out into the temporary space. I had forgot to get a pic before I moved out the subs frown.gif and I wasn't about to move them back...

Forgot to mention, this ridiculous small room is 7' x 9.5' with a 7.5' ceiling... so 499cf. Using the ULF calculator I get less than 88. That doesn't account for the room being overstuffed with speakers, boxes, amps, and of course 14cf+ of subs. It was good times for sure. biggrin.gif


Summary relevant to this thread -

2 x LMS-U 18's FP14K clone
2 x LMS-R 15"s dual opposed inuke 6000DSP


My current score @10Hz - 263

Prospective score in larger room @10Hz - 561

Stupid score in stupid room @10Hz - 88
please don't put this one in your list dominguez1, as it only lasted a couple of hours tongue.gif

I will run your LMS the same way I do it and see if I gets better. I missed the clone after sellin it to you so I bought another!

Here are different drivers using a box to get close to .707 and power to reach X-max at 5hz. They go from most displacement to least.

Whats up dominguez1. Here is a link with some test results for the VTF-2 MK4. Scroll halfway down to find them. Graphs are 1m groundplane and then bellow them is some 2010 CEA2010 results. Im running both of mine 1 port open in EQ1 setting.

Yes!!! Thank you cubalis2. Exactly my thoughts. 

 

Nothing will replace a nice sweep of your room showing max output and THD...but, most don't have the equipment and if they do have it, might be hesitant to perform those tests. The ULF score is a great 'ballpark' type figure that will give you a general idea of how your HT ULF setup stacks up to other members.

 

Having said that, it's great to see members like bosso and ricci chiming in...giving hope that perhaps this score could become a science. But until then, it at least gives folks an idea of where they are at.

 

Like I've said before, I think the 'science backed' ULF score is plus or minus a 1/2 star...meaning some 4.5 star systems could be 5 stars, and some 5 stars systems could be 4.5 stars when you break out the measuring stick, but it's probably unlikely that a 4 star score could in actuality be a 5 star score.

Nice setup! You don't mess around with the SQ thing do you! LMS-U grads gotta stay true to their alma mater's! Please share a pic. Were all cabs made by Funk? Talk about art..

Awesome story. Particularly with the highlighted above! I LOL'd that one...

 

88 is crazy! You're right, probably lower than that. Not sure if you've been following along, but if Popa sealed his room, that's what it would be like... :eek:

MK, what's the significance with the .707?

post #225 of 1882
That is supposed to give you the flattest and true rolloff sealed subs provide I believe. As you can see all the box sizes change accordingly. The advantage of the LMS 5400 is that it requires a tiny box to do so which is nice in a living room! Also drivers may or may not be linear so that could change things. The SI performed very well at DB because the box Ricci used was close to ideal for it. Many drivers did not have a box big enough.

Only the 4cft cabs were Funk made. I actually picked up one of the original designs from a few years back. It was a prototype box with an Aura NS18. One night while I was away someone let loose on it for hours and fried the coil. Once I found out, I decided to replace the driver with the LMS-U... a year after that I asked Nathan if he could replicate the box and it was done - a perfect clone with another LMS-U.

The dual opposed 15" box is a very simple mdf box painted black, which was meant to be hidden at the time. I think I'll end up veneering it and finishing its empty twin box which sits in storage.



Here are some quick pics from moving things around and testing out the big room today.






With a bottle for size reference... blu-rays are still packed away so I substituted with something tastier biggrin.gif

About 45watts should be enough to reach Xmax so you probably did the sim. currect. 324points you say... Guess that puts me in the lead of the 4.5-star group then.

At the risk of sounding like a tape loop, it performed very well because it was driven by an absolute monster amplifier on a 220V-50A line. 12,000W bursts of shaped noise. eek.gif



You simply cannot have the top end output numbers and the low end output numbers in a single system without serious limiters. Even then, the SI would disintegrate if you opened that amp up. It's just not happening.

Model the SI-18 with 12KW and post the graph. wink.gif

I'd like to see the same test with a Berry, CV5K, IPR, iNuke, XLS, etc. on a 120V-20A line Amps DIYers use.
post #230 of 1882
Just to play devil's advocate, doesn't the same hold true to all the drivers? In that case, then one could say X driver performed well relative to the other drivers tested under the same condition. Once everyone recognizes that they won't see the performance the d-b shows, they can still compare one vs the other, no?
post #231 of 1882
What a cool thread Dom!!

I have four CHT VS18.1 passive subs along with a pair of JTR Captivator 1000s also passive. All powered with Crown XTI 4000s.

For the JTR SI I noticed others in the thread mentioning that DIY UXL 18 is a comparable reference so I went with that. I know my results are not "official" but that doesn't mean that I cannot join in on the fun!! smile.gif

My room is 1404 cubic ft so four CHTs @ 1.5 SI is 6 and two UXL @ 1.6 SI is 3.2 all @16hz = 1404/9.2 = 152.6 @16Hz.

I will gladly alter my results when newer information becomes available.

Correct.



Using the min voltage and associated watts as the max power supplied for all frequencies, the above chart shows the new spl output at those frequencies. Not perfect because compression is not linear, but should be pretty close.

As I understand it, to get to the output that josh measured at all those frequencies, you'll need that massive amp and have some sort of tailored voltage limiting curve to limit voltage at each frequency. I'm guessing that is the benefit of going commercial, as many have that built into their specific amp?

Wow, that is some Massive 16hz output!

Nfraso and others, we landed on an estimate for the subm@10hz, lets take a shot at the jtr cap.

On the road, or else I'd do some quick math...

Any thoughts? I would think 16hz would be the frequency we'd highlight.

The Cap1000 drivers are closer to the CHT drivers, the Cap2400 drivers are closer to the UXL-18 drivers.

Thanks MK! So using CHT instead of UXL for my comparison I get 1404/9 = 156 @ 16Hz.
post #236 of 1882
Yes, state of the art bass to 16hz! Your 20hz would be even better because that is the wheel house of those ported cabs! You hit 111 dBs at 20hz and you have 6! 104.2 for the SI so you at like 14 SI's with a 1404.2 cubic feet room! Close to 100 at 20hz! You will have about 3 dBs more than dual Cap 2400s!

Yes you are right it would be 106.4 @ 20Hz. That sure says a lot about the Cap 2400s though. They would have been worth the extra $600 it seems.

I am utterly befuddled by all this...


I understand that Josh Ricci is using a beast of an amp to test the absolute limits of each sub, and that they are controlled experiments that therefore don't result in the same rapid transients and combinations of wavelengths that a driver playing music would have to deal with, so the max outputs achieved and measured by Josh are effectively unachievable in 'real life' uses.

But... going from the post above and the previous posts on this, are we effectively saying that any 'normal' amp in 'normal' use is unable to control voltages enough to ensure that THD distortion levels are kept in check at certain frequencies in the driver's range, specifically focused at and around the peak impedance of the driver where only a minimal voltage / power is required for the driver output to reach the same level as those levels across the wider bandwidth that require a lot more power to achieve due to lower impedances?

Are we saying that, in this example, a 95v input across the bandwidth range is going to wreck the driver in the bottom of the range due to excessive THD levels, so we must therefore apply a limiter across its entire bandwidth so the driver does not 'see' more than the voltages required at the peak impedance point (53v), effectively limiting output?

Is such a limiter possible? And how are the various systems that are giving drivers around double their rated power (popalock's and carp's, for example) actually surviving this onslaught if the THD distortion rises so massively and they need so little power at the peak impedance point? Are the amps reducing the power at this point? Can they do this when they are playing multiple wavelengths that include these peak impedance points as well as other points further away from this? Or does the amp just react to the driver rather than the amp dictate what the driver is given?


I'm sure all the above are dumb questions but I need to get them clear in my head - having bought a CV5000 to run four SI18s @ 2Ohm (1250wRMS each at max power) I'm wondering if I've gone completely overkill, even though the WinISD modelling showing it's safe excursion-wise even under full power...

I'll try my best to answer...and I'm sure someone will jump in if I misspeak (this is AVS afterall :)):

 

Yes, a DIY amp paired with a DIY driver/box do not optimize each other by themselves. In order to do so, you need some sort of EQ. This is why commercial offerings are great...the amp is specifically paired to the box/driver capabilities. Additionally, the commercial sub has it's amp tailored to the box/driver specs to get its full potential within the limits of its weakest link (think of offerings like the SubM or Rythmik, etc.). I'm assuming this means being able to vary voltage with a tailored EQ.

 

This seemless integration is what you have to compensate for when you go DIY. In Josh's tests, 95v was the absolute limit for the SI before bottoming out for that frequency. Apply any more than that at that frequency, could potentially damage the driver...remember, 95v was the max limit to prevent driver damage, not THD. To keep under THD (without a tailored EQ), you'd have to go with the 53v as being the limit.

 

Also remember from a THD standpoint, we are talking about groundplane measurements. The room plays a part in THD, and as I understand, helps from a THD standpoint depending on the room. So although 53v may be the limit in a groundplane environment, it would likely be north of that when bringing it in-room.

 

Also know (as I understand it), bottoming out a driver is completely independent of the room. IOW, 95v will bottom out the driver in-room or anechoic. Also know that the power output in the chart was peak, not RMS. Someone correct me if I'm wrong...

I read that you picked up another, I feel bad that it ended up costing you extra, but I'm not sorry you sold it wink.gif

Only the 4cft cabs were Funk made. I actually picked up one of the original designs from a few years back. It was a prototype box with an Aura NS18. One night while I was away someone let loose on it for hours and fried the coil. Once I found out, I decided to replace the driver with the LMS-U... a year after that I asked Nathan if he could replicate the box and it was done - a perfect clone with another LMS-U.

The dual opposed 15" box is a very simple mdf box painted black, which was meant to be hidden at the time. I think I'll end up veneering it and finishing its empty twin box which sits in storage.



Here are some quick pics from moving things around and testing out the big room today.






With a bottle for size reference... blu-rays are still packed away so I substituted with something tastier biggrin.gif

The scotch I have but can only lust after those subs....
