56 seems a little low. Definite risk of an underpowered setup.

With room gain the manufacturer said 125db at 7hz.
This was confirmed at Trinnov as ok , by the 2 Arnauds after modelling the final positions.
If a six by six configuration of double svs inwalls worked in Brazil how could this arsenal not be superior? Especially powered by so many 700 watt Elipson A270's?

Report back on the listener experience.
Personally I had a taiko drum performance damage my hearing. You can speak to an audiology professional on your plans for programming.

Domo Arigato my dear sir, as we are working hard at finishing the shop drawings. The floor is transparent to 150hz ( spaced Timbertech decking) With cooling M&E and isolation responsibilities too boot.

How low do those drums go? I have had experience with rotary subwoofer, our ears are not that sensitive sub 20 , in this video I filmed it felt like Hurricane Andrew was outside the house.

Are those Hushframe brackets on the walls facing the adjoining spaces? I'm imagining you'll need a lot more than that to keep that much bass from carrying through those walls.

This is a Garage conversion on a second home (limited budget) so no adjacent room per se.
Initially we were just going to going to use two layers of sheetrock 5/8" but then we realized that this method is lossy in the frequencies that Waveforming is working on.
So as a compromise we replaced the outer layer with Quietrock to add some stiffness at those frequencies. It is all a compromise the whole thing will be built for under $300k. The idea is to provide multimillion dollar value for a song. I will only do that once it has been a year worth of work largely pro-bono in the deign stage.
We placed the a/c outside of the room with the silencers as close as possible to the air handler. As you can see no contiguous rooms, THE BIG ISSUE are the rooms upstairs there is only so much we can do remotely.
The a/c ducts need to be augmented, not to the full capacity of the videowall heatload, but 66%, there is accounting BTU's for 12 people , the large windows are a big range variant but , being in Michigan with some shadows from the trees we are asking AI to be conservative on the window heat load. Let the HVAC contractor sign on the dotted line, but there will be 2.5X the ducting for sure.

And that's a great place to put the woofer...right next to the Revox and the tape...

I know right!And that's a great place to put the woofer...right next to the Revox and the tape...
-To be frank, it's merely sitting there for decoration these days; ReVox's current claim to fame is their innovative invisible speakers, complemented by an exceptionally high-quality center channel that I am eager to send to AMIR for review.The right reel demands a precise adjustment of its locking mechanism, and the unit is due for a comprehensive overhaul. Regrettably, I haven't had the spare funds to ship it to Switzerland, nor do I possess the relevant media content. It is conspicuously displayed on the kitchen bar, boldly declaring that there is no place for conventional two-channel audio content here. Instead, the space is filled with Atmos BDs, Pure Audio, DVD Audio, SACD hybrids, and multichannel downloads. This setup represents a 45-year personal crusade against the limitations of stereo sound.

Open reel decks are great for that!
20 something year olds (our son's friends) always ask "What the hell is that thing- it looks cool, but what does it do?" The look on their face when I say "this is how music was recorded..." is priceless- like I am from another planet or something. LOL.

@CINERAMAX Are those KEF in-walls? I'm shocked, what happened to Alcons, Quested and Starke? And for the subs, no more custom Geithains?

Hi,
Stephan,
First: The KEF Ci5160REFM-THX is an in-wall architectural speaker that is THX Certified Dominus, the largest and most powerful THX performance class. It is designed to provide a cinematic experience with its Metamaterial Absorption Technology (MAT) and four 160mm bass drivers that can produce clean, rich bass down to 32Hz. The speaker also features a 12th generation Uni-Q driver array for acoustic accuracy. The Ci5160REFM-THX is intended to be discreet in appearance
Yes it is Kef, this is a vacation second home, and I have a construction budget cap of $300k. Quested has dispersion issues. Starke owns a Klippel but won't share data. What happened with Alcons? You might recall a spat with a Tyrolean I brought to CEDIA as my assistant to handle Alcons. He ingratiated himself with the owners, despite needing 20 attempts to get a calibration right. The ingrate took credit for my California PH project while I was having a heart bypass, even publishing about it. I called him out, and he wouldn’t let me use his Zeedoo player at the CEDIA Alcons Booth for a moving bass test with the waveforming setup that belonged to Alcons. I got tired of dealing with such people.
Besides, the only Alcons worth their salt were verified with seven spinoramas from Pierre with seven speakers at The Infocomm booth. The Harman score correlation was extreme, which turned me into an objectivist. You can achieve prodigious levels with soft domes using the right waveguides; there is no substitute for the linearity of coaxial domes.
Speaking of coaxial domes, the Elipson Planet L are amazing for object audio and very inexpensive, playing very loud. The Marantz AV10 was amazing with four Perlisten D-15 in the directional bass modus. I heard some of the best claims from the Trinnov CEDIA Ascendo experience, such as hearing bass from the front wall with movie content and four-corner ping pong bass in multichannel FLAC music; you cannot get the later out of any other system, having both elements adds a new plateau of possibilities.
From now on, I will follow the next generation of driver and crossover changes in the Planet L very carefully and am tempted to start importing them, which perhaps offers the best imaging of all coaxial speakers. The spherical shape contributes to the flat on-axis response (except the coax dip), and the speakers are also radial diffusers. Positioned away from walls, the direct-to-reflected ratio is surprisingly effective in compensating for the untreated parts of the room retrofit. in this 60 grand system that beat all my 15 million dollars worth of previous work. I am enjoying my new high value business paradigm in Miami. If I could get Amir to measure the next generation....

quick and dirty Elipson Planet measurements
I recently purchased a pair of Elipson Planet Ls and again some Planet Ms. I got some for great prices and wanted to add surrounds that would be permitted by the wife. The Ls do look very nice in Mercury Ice on the dedicated floor stands! Given they are both concentric driver speakers I...

After releasing the shop drawings, the client requested an increase in the traffic flow in the utility room by moving the rack against the wall.. Additionally, after consulting with the house architect, the client decided against the larger windows. Designing a lounge from the waterside inward, when there are no neighbors to observe the window disparity, is too narrow-minded. Since the lounge is the most important room in the house, the larger windows should have prevailed. The only saving grace is slightly better acoustics, slightly.
The slide below addresses a problem that could have gone unaddressed when outfitting a theater with quad force cancelling subwoofers, they are pretty much inert except one form of potential vibration induction....GRAVITY. Shown below are the gravity vibration damper support.
without them as on the next slide where they were removed there would have been some minor vibration. You absolutely do not want that in a videowall general area.

Someone on Facebook was claiming that the kef ci5160thmrefm speakers needed to be toed in, absolutely no, that is the beauty of coaxial.
Looking at the cea 2034 dispersion plots for videowall usage I PREFER to deal with a narrow 30 degree dispersion window (in total 15+15) welcome to the wonderful world of videowalls and window based immersive spaces.
We got decent coverage at 30 degree for 3 individuals now that the rear surrounds were moved 5 inches closer than here:
