I'm not the first to say that the basic premise of the 901 is fatally flawed. Bose determined that the sound reaching the audiences ears in a concert hall was 11% direct from the stage and 89% after reflecting off the walls, floor, and ceiling of the hall. So the 901 imitates that ratio with one forward facing driver and eight rear firing. Yeah, but a recording of a performance in a concert hall already contains the direct and reflected sound reaching the recording microphones, from different directions and at different times. It's more than a little simplistic to think you can simulate the 11%/89% concert hall direct/reflected ratio through two speakers playing recordings made in the type of room you're trying to simulate. You're actually doubling the direct/reflected effect with the 901, you see? You would need to make a recording in an anechoic chamber, one mic for the direct sound and multiples for the reflected. Then play the recordings on a system that mirror images the recording mics---one speaker facing the listener and eight firing from the sides, back, and ceiling.
And what about a recording made in a studio? Here, the direct/reflected premise is more than meaningless, it's completely wrong! Is it any wonder that the 901 does not, in fact can not,image?
Then there is the matter of trying to reproduce bass through 4-1/2" drivers! Not to mention high frequencies!! Nope, sorry---can not be done. One listen to a 901 will confirm that.
