easy fellas.. everyones perception of sound is different.. what one finds bright, someone else might find flat..
we all have our opinions, and we all dig our speakers.. thats a good thing. we dont need this to be a negative thing.
kenturkey- hopefully one of the guys that have M2's or M3's as centers will chime in. i would suggest to use the QS4's or QS8's for surrounds.. the quadpolar design makes for one of ther best sounding surrounds i think i have heard, regardless of price. and front firing speakers are usually considered better for rears, so an M2 or M3 would be perfect for your rear channel.
