As far as the "axiom sound"...details, details, details. You'll hear things you've never heard before in recordings that you THOUGHT you knew very well! Crystal clean clarity in the midrange. Voices sound like they're in the room with you. Bass...tight. Not huge, not boomy, but tight and fast.
If you like these qualities, then Axiom is THE speaker for you. If you prefer laid back, smoother, mellower sounding speakers, you'll HATE Axioms (at least their M2, M22, M60 and M80's). It's really all up to your taste in sound.
When you listen in multi-channel is it going to be mainly for movies - with 2channel listening for music? Or do you generally listen to your music in multi-channel as well?
If you are a 2 channel music listener, as most people are, you really should get the QS8's for surrounds. They're designed for the dispersion used in movie surround channels.
If you do happen to listen to most of your music in multi-channel - using DSP modes, etc...then yes, the M22ti's being used in the surround postion would be a good pick.
Lastly...unless you're going to be in a REALLY big room, the M80's are overkill. Even Ian (Axiom founder) has said that the M60's and M80's sound virtually the same. The M80's can just go deeper and louder. If you're really going to be getting that moster SVS sub, you certainly have the deeper end covered. And unless you're in a cavernous room - the M60 will more than meet your loudness needs.
Lastly I need to plug Hsu Subwoofers. They ROCK. Be sure to research them as well before you make the SVS jump. Though I'm sure you'd be happy with either one.
Good luck, and start that "Upgrade" fund now!
