Once your speaker is repaired you may want to download or purchase a sound level meter. Most music is mixed using 83db (C weighed, slow response) peaks as a reference. If you are playing louder you may be risking not only your speakers but your hearing as well.
How does a speaker blow out?
I don't understand how a speaker "blows" if the wattage of the amplifier is less than the upper limit of the speaker's limit. Then again, I guess I don't really understand what "clipping" is. The amp is 22w, I was listening at a moderately high level, there was a bass heavy section in the music, and then I heard the most painful noise coming from one the of woofers. Sad.
