It's very possible that the reason the JBL speaker blew out was due to lack of amplifier power which caused severe clipping distortion causing the woofer to distort.
In other words, the more dynamic range you have the more amplifier power you need... every time you increase volume just 3dB your amp has to double the power delivery to play without distortion or clipping. If it can't then you'll be blowing your speakers.
And as the dynamic range increases the average level decreases... so in order to maintain the same average level the volume will need to be raised... again necessitating more power.
I bet you thought this was going to be easy! Good Luck.
