My room is 1500 cu ft but I'm running it at 1/3 of its capabilities. The LVX12 should be fine (for most people) in rooms up to 3000 cu ft.

I think $30 millions is not even close to real price. As today there are only four of those fully functional and two are at the Ferrari Gallery

Pretty remarkable considering they didnt build many more than that to begin with.
Most I can remember seeing for any car was a 1962 Ferrari 250 GTO. $67 million.

We have to materials for the grills. The one I showed first is the most transparent and it's usually the one we use for piano gloss finish subwoofers. But when the grill is on it doesn't look that transparent.

Can you buy the more transparent grill for the non piano gloss models separate?

So I have a big problem (I think). I popped in Edge of Tomorrow this morning since I heard it was a good movie to watch for the LFE. At the beginning, before the movie really started, there was a crazy sound that came out of the LV12R that did not sound right at all. When I got up to switch it over to High (it was on Low) i noticed it wasnt on, and it wont turn on - even when plugged in. If I put the switch to On or Auto, no lights. Any idea what happened here?

Not sure but that movie is known for a very loud 10Hz sound in the very beginning.

My 2 guesses would be either the driver bottomed out OR, more likely, the amp received too hot of a signal and a protection circuit kicked in.

Was the amp hot after this happened? And did you try turning it on again a few hours later?

You should probably email or call Brian for the fastest resolution.

This happened right before I wrote the message so it hasn't been too long. The receiver was not very hot. The power plug into the back of the LV12R seems very loose - which is weird. Regardless if it's plugged in, no power to the subwoofer. I'll contact Brian, any idea the phone number and hours he's available?

The 10 Hz tone would not have been the issue for the LV12R as it is rolling off most of the signal by then. The 15 Hz tone is right below tune and would likely have caused extreme excursion.

Most probably the thermal protection circuit went off. Unplug the subwoofer power cord and wait a few mins then plug the power cord again and turn the subwoofer on. EOT is a killing subwoofer movie. If you are running the subwoofer hot then you have to bring the level on the subwoofer to Audyssey calibration original level for the subwoofer in order to not damage the subwoofer. Also make sure your center channel speaker is set to 80Hz. There is a lot of reports of center channel speakers damaged due to this movie.

Figured it out. The fuse under where the power cord is plugged in (found the pull out compartment) was blown. Luckily you good folks not only protected the sub from destroying itself, but you also provided an extra fuse within the pull out chamber. Fixed it. Recalibrating using MCACC now and I'll leave the sub at -6 for the duration of the movie. Crossover is 80hz for all speakers. Cheers!

I see, forgot about the rumble filter and natural rolloff of the LV12R.

Just to clarify, this thermal protection circuit is different from the limiter, right?

I had the sub about 6db hot. I always calibrate to -6 and then boost it up to 0. So it was at 0 and I had the volume pretty loud. My receiver counts up from 0 and I had it at 55. Not sure where that is in relation to reference though. The sub sounded a bit rattly during MCACC. I'll check it with a movie in a min to see if I did any real damage. Why would sound producers put such low frequency sounds at such high volumes in a sound track. Seems stupid to me. The vast majority of people don't have the equipment capable of reproducing those tones. Some to the point of damage like may be the case for me.

EDIT: So far movie sounds fine - no rattling in sub - probably just the test tones of the MCACC playing jokes on me. The receiver goes from 0-80 and i listen at 50-55.

Hope everything is alright with the sub. I noticed that when using the LFE input on the sub, the YPAO test tones had a rattling or clattering type sound. Not with Line In, though. Probably has to do with LFE bypassing any sub LPF.

What is sub LPF?
The low pass filter (crossover knob and lpf slope switch)

By the way, when you get REW you can do compression sweeps (carefully) and determine at what volume setting on the AVR the sub starts compressing at 20Hz.

Also, keep in mind that MCACC could be setting the sub a bit hot all on its own (YPAO sets mine 6-7 dB hot all on its own) AND that bass management adds to the LFE too. And the more speaker channels you have the more bass management is sent to the sub. All these things can make the sub play louder than it would otherwise.

So, how loud the sub plays is based on whether the sw trim is running hot and by how much, the number of bass managed speaker channels, and obviously the AVR master volume (MV).

And regarding bass management, if you don't use upmixing, 2.0 has 2 channels of bass management, 5.1 has 5, 7.1 has 7, etc.

So, a 5.1.signal will have the sub playing more softly than a 7.1 signal by a few dB.

Got it - I'm playing in 5.1 with PLIIz on to power the front heights - so 7 channels. Just got to the scene where they crash and he is floating under water. The sub made some not so nice sounds. Sounded low, so not clipping or anything, but possibly was just a frequency too low to hear. Besides that part and the one at the beginning, the sub has handled the movie wonderfully. The whole system sounded great. I'm at 55 now and im assuming this is close to reference as it is very loud - just below unpleasantly so haha.

First Ive heard that. You confirm that with REW?

When I got up to switch it over to High (it was on Low) i noticed it wasnt on, and it wont turn on - even when plugged in. If I put the switch to On or Auto, no lights. Any idea what happened here?
Woops. Might not wanna do that again.
Its a Rhythmik but its the entry level Rhythmik. Adjust your standards accordingly.

Well I wasn't searching out that scene - just read that it was a good movie for LFE so decided to pop it in this morning. It's a bit scary that at the normal volume I listen to movies with my EQ as it is, there's a chance that some random scene in a movie could do that to the sub. Guess from now on before I watch a movie I will look it up online to see if there are any watch-out moments like that one. So far I've seen just Edge of Tomorrow and Django have Subwoofer killing parts. Any others off the top of anyones head they could think of?

Theres no way thats the case.
Youre either listening way too loud or have the sub way too hot.
Ive had the LV12r for 6 years and have never had any problem.
