People do often assume some sort of proportionality between number of speaker channels and the volume of a listening room, but I think having more speaker channels is all about greater quality of sound, not filling up more volume. (I use "speaker channels" rather than "speakers" to allow for the case of theaters using multiple speakers for each channel, which does seem to be a matter of filling volume.)

I don't see why it should ever end. I'm at 7.1 masquerading as 9.3 -- it's not actually 9 since I can't play my back surrounds and front heights simultaneously, and it's not actually .3 since my 3 subs all play the same signal. I'm looking forward to getting a real 9.2 system, then 11.2, and onward from there.
