I'm glad you posted that Feanor. It's become tedious to respond to these kinds of questions about wattage ratings on speakers. Only those who are relatively new in this hobby pay much attention those types of ratings. Unfortunately for "newbies" they get caught up in those kinds of figures.

It seems to take a while before some folks realize that speaker wattage ratings are essentially worthless. They have nothing to do with how a speaker sounds or how loud it will play.

If you don't have enough power and try to get high volumes your amp/receiver will clip and distort and maybe blow a tweeter. If you have too much power and try to get very high volumes your speaker will get overdriven and distort and maybe blow a voice coil. Either way you get distortion and possibly blown speakers. If you pay attention to how things sound neither one of these scenarios will occur.

IOW: When it starts to sound harsh and/or distorted turn the volume down!
