OK, these have some power. Not only that, they sound great. They are a bit heavy on the highs and lows - but after a bit if tweaking you will have a perfect sounding system. Did I mention the power? Let's just say it will make your ears ring if you live in a single family house - and your neighbors hate you if you live in an apartment.One complaint (which is the sole reason for the 4 stars)...since I installed the speakers I have been picking up some radio/TV sounds in the rear speakers. I've changed the wires...still there. Changed the power supply, installed a filter for the power supply - still there, still there. I guess I'll invest in some pricy shielded speaker wire and see how that works....This is more than likely the result of living next to the many radio broadcast, and TV stations in D.C., so unless you live near me, you may not experience the same problem.All in all, these speakers are worth it.
