Gena: just because you have a speaker rated for 100 watts does not necessarily mean that all the drivers in the speaker are rated for 100 watts. Somewhere I recently saw an article/ post on this. It could have been on this board. Bottom line, because of the actual musical power spectrum, the tweeters are rated quite a bit less than the actual speaker rating by most manufacturers. Wish I could remember how much.
