If you are hearing a lot of distortion, you are pushing the amplifier too hard. That is one issue.
A 50 watt amplifier can put out more than 50 watts when it is distorting. Remember, the 50 watt rating is max output WITHOUT any significant distortion.
On the other hand, it is more likely that the speakers are not really able to take nearly as much CONTINUOUS POWER as you think,, because of the age of the cones.
If you get new drivers from Klipsch and install them, they will no doubt hold up better than the 10-year-old ones.
Klipsch does rate them at 100 watts RMS continuous power when new, and even with high distortion your amp can't quite do that much.
