Dunno for sure. Pose the question to Definitive. My questions have usually been answered with a day or two.

My guess is that your answer will be be something to the effect the speakers are compatible with this range of watts.

It's not THAT important to be concerned with the number of watts that speakers can handle. Most can handle quite a lot of clean power. The rule of thumb is when the speakers start to make strange popping or clunking noises, it's too loud - turn it down (usually giving speakers too much power). Or, if the music starts to sound harsh and flat, it's too loud - turn it down (usually running out of amplifier power).

All that said, my Definitive BP-30s are rated up to 500 watts. Well, I can tell you that they would not stand up very long to the full continuous and peak output of a Crown K2 which is rated at 500wpc.
