Infinity lineup: well, it's not a fair comparison 2000.6's to RS's, or Kappa 9's. Apples to rasins.
Maybe RS6b's, but Emit and Polydomes still have the edge.
I have two pair, Awesume 5.1/7.1 system, front mains. With a CC3 center, and a pair of 2000.1.s as surrounds, and a subwoofer. Truely stunning surround system, when driven w/ TrueHD/DTS-HD receiver.
For music, they are marginally ok, short on bass, due to the small 6.5" drivers.
My two cents Stu
