How good is the Axiom speakers....

I'm interested in M22Ti...M3Ti...M40Ti which get positive reviews from users.
Can anybody describe their characteristics...their strength and their weakness.

I use PSB Image 8C as the center speaker which is really good.
Can these Axioms blend well with my PSB.
I intend to find a good pair as fronts to replace my MA Silver 3.

They will blend just fine until you hear your Axioms with a better center channel.

The PSB is a fine center speaker. Actually, any of the Axiom speakers you mentioned would be good choices. You didn't mention if you have a sub or not. If you don't, then the M40 and M3 would probably be the better options. If you do, than any would be fine. I auditioned some of the PSB line against axioms and I thought that they were excellent. The Axioms won hands down when it came to value however.
