So I found the Quantum and it ticked off all the feature boxes for me, and the price was right. Check the connectivity guide for compatibility. The JBL's are nothing but hollow plastic with no sound deadening or dampening. Frequency Response. This replacement pair will have the same structural issue, and will suffer the same fate. From the tiniest footsteps to the loudest explosions.
