It isn't something you would really "notice" in a straightforward way, but there has been research to this effect. I'm sure in some cases the effect is neglible, and as above in some extreme cases...

Surprisingly the brain will pull the image down quite easily to match the perceived L and R height. But there are of course extreme cases, especially when using a big 16 x 9 screen, or a very high...

That makes no sense. Based on your suggested bracing scheme, and explanations of it, I cannot help but conclude you simply have no idea what your talking about.

Single speaker above.

Placing two, one above and one below, will cause serious lobing artifacts in the vertical plane.

Placing one below, while OK, is much easier to localize (if you're an...

If you had a known problem mode of narrow bandwidth, you could attempt to turn it into a pressure/resonant/membrane absorber. Perhaps using pegboard covered in fabric. Would have to identify a...

Strength isn't required in a speaker panel. The forces are quite small. Stiffness, mass, and damping are needed, probably in that order. MDF is particularly good when it comes to mass and damping....

Your idea will work. The suggestion made in this thread is better. Noise isn't really the problem. Well, at least its only part of the problem. Its best to think about this in terms of distortion....

Well, some, but not all are complimentary.

I guess that might work. But at >$5k for the pair, it isn't exactly a cost effective solution. For the same money, a stack of miniDSP products could provide 20 digital or analog inputs and up to...

BTW Bassthathz,

The motu products are pretty cool. I'm probably still not entirely clear on what function they would serve in your system. I was thinking it would need to handle crossover...

It is designed for commercial cinemas. Doesn't mean it can't be used in a home environment. Has already been installed in a couple of LA/Hollywood producers homes from what I understand.

No direct experience, but if I had the cash right now I'd seriously look at the Lexicon QLi-32 in the chain, which would of course require a BOB-32 or two to convert output channels. Would be...

I found a few 4 channel proaudio options that seem reasonable, all coming in at or a little below $100/channel. The Art SLA4, the Carvin DCM2000L4, and especially a couple of models from the German...

As another reference point, using the behringer epq europower series, for those 100 channels would probably come in around $10,600, a decent savings, but in 40 (smallish) boxes. Probably take up the...

What would you do? Lots of amp channels.

Let's say you want to pack a lot of amplification channels into a theater build. Let's say 100 channels to give a round number and make for easy calculations/comparisons. Ignore for a moment the...
