Summary: It was a very good choice to go for the polk rti10. The price/quality is very good. Harman Kardon HK3485 High Current Stereo Receiver with these speakers, i like the sound very much. It only lacks a little bit of bass. I was going to buy kef's, but now i saved money and i'm happy.
Summary: If these sold for around $400-500 instead of $600-700, I'd say they were pretty good. However at their usual retail prices around $600 you can do better with lesser known brands like Paradigms, Monitor Audio, Ascend Accoustics, and Axioms. But the RTi towers are much better than the RTi bookshelves.
