Disclaimer: Not to sound like a dick, but I prefer only those respond that are very solid in their answer. Opinions (guesses) I don't need, since they are probably about as much of a gut feeling as I have about it. I.E. 04, Zemo, and some others I'd much appreciate your advice. Thanks. I will be receiving a pair of infinity kappa perfect 6.1's within an hour that will replace my polk audio mm6 components. The problem I have is that currently I'm putting about 200w/channel to them, and they are rated for something like 150W RMS. No problems with that much power so far, and I don't turn them up loud enough to use all that power. The new Infinitys are only rated to 100W RMS, but have 400W peak power handling. Significantly more dynamic range than my Polks. So, the question: is it wise to run 200W RMS to these speakers? I know it's almost always better to overpower than underpower, but is this pushing the limit? I also want to use my Eclipse CD8053's internal x-over rather than the supplied one, which I would be forced to use if you guys say I should only run the 100 watts, making me run them off one channel of my amp. Currently I am bi-amping (or is it bi-wiring?) my mids and tweets (one channel to mid, one to tweet).
