Question about Velodyne DLS4000R Subwoofer Speaker
I've encountered the same problem with the subs popping at high
volumes. Being an electronic hobbyist myself, I've open up the power amp module
( the rear side with a enormous heat sink ).
I managed to identified my problem due to 1 of the 2pcs of 4700 / 63V uF capacitor leaked ( aka reservoir caps ) and that leads to shorting of an NPN transistor D669A. I've since replaced both the 4700uF / 63V uF capacitors ( advisable to replaced a pair ) and the faulty D669A transistor. So far, my subs is working like new again...lol.

Popping ????? if popping sounds mechanical: chek for speaker blowned (replace or repair speaker)
if popping sounds electronic: chek circuitry.
