I have posted a few questions here already and have gotten some pretty good feedback and opinions. Most of the people here seem to be unbiased and very knowledgeable. So, here is my dilema. I am trying to upgrade my speakers (Polk Audio RM6600). Would like something awesome for both Home Theater and Music. Would like to move up to floor standing fronts and di-pole rears. And, Yes, and SVS Sub. Currently leaning towards axiom. Mainly for one reason. Running system with a Pioneer Elite VSX-45TX. Manual says that I can adjust to 6ohm. Question is, would it be a serious problem running 4ohm speakers??? Reason I ask, is because for about the same price, I could get Swan Diva's or the Onix Rockets. Diva's di-poles are 4ohms and the Rocket center is 4ohms. Ideas, Help, and Opinions would be greatly Appreciated.
