After going back and forth between the Axiom M22ti and the B&W DM602 speakers for up front I purchased the B&W at a great price. I really like the Axiom surrounds though- the QS4 or QS8 speakers seem like an ideal rear/surround channel set up. I have a 6.1 system so I'l need three. I know the center and front speakers need to be timbre matched and I've heard the raves of using five or six identical speakers too. Question: Would I take away from the balance and tone of my system by mismatching brands between the front and rear? I am not sure if the Axiom and B&W are audibly compatible. If I stick with B&W I'll probably use three rear 600 or 601s.
