Axiom M22ti are very nice sounding! Axiom
The750THX system is a really nice setup. I have heard it and for the money would not disappoint. Here is a review: M&K Review
Properly set up, with decent room acoustics, good power, (you don't have to go overboard) and use 80Hz as a crossover, it is a dynamite system. I was running mine for almost a year using the internal 100Hz crossover of my receiver. I got the Outlaw ICBM and set up the front 3 speakers at 80Hz. It was like an upgrade.
(I only use the surrounds for 6 channel DVD-A or video, so those are set 'small' in my DVD player and cutoff at 100Hz. )
It sounded just fine before, now its sounds incredible, in 5.1 or 2 channel stereo. Mainly for rooms under 2500 cu ft. About the only thing I may change is adding another sub. Great speakers! Punchy, smooth, and accurate.
