As long as I've been researching speakers, most manufacturers websites give a recommended min/max amp rating. I think it is just a recommendation and you might be reading to much into it. Look at the 80's, they say 400w for max power. We all know they can handle amplification that far exceeds 400w. As I've mentioned before, in recent lab tests Axiom when testing the new amp drove a pair of m80's continuous for 2 weeks 24hr/day with 700 watts with peaks exceeding 1100 watts.
