What would a stereo sound like in here?
Well, given that there are no reflections, you would hear 2 individual sources with perhaps some middle fill. You would also hear just what your speakers sound like without room reenforcment and comb filtering. So, problably the closest to "flat" you'd ever hear. Now you may not like the "just the facts" presentation, but that's what you'd get.
As far as how would different speaker sound, dipoles would be half as loud, since the back wave is gone. There'd be no bass cancellation. Omnis would have problems, since again all of the "room energy" is absorbed.
Also, reports have stated that a person really can't stand the level of isolation for long periods, so I'm sure the room would wear on you.
