Alan: I'm interested in learning your take on the 2 models. Advantages of M80s paired with a sub over the M22s paired with a sub? And vice versa? Obvious would be the fact that one would certainly expect the M80s to produce greater SPL. Given that someone has a THX-Ultra-sized room (around 3200 cubic feet), and given that a sub is always in the mix whether listening to 2-channel (50% of the time) or multichannel DVDs (50%), what would you recommend, and why?

What are those subtle differences, if any, in the range 200Hz and up?

Thanks!
