You got 22 watts, you can't play loud on most loudspeakers with 22 watts. Low power is bad for loudspeakers because the waveform comes to a sudden stop and the driver goes out of control. Damage happens long before you hear the distortion. Turn it down and live within your system's capabilities.
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.
