Odd speaker failure
Posted: Sun May 05, 2019 6:12 pm
Thought I cooked a LAB12 in a T39. My brother used part of my rig at a DJ gig for a wedding g reception.
He said he didnt run it that hard, but said halfway through the night, he assumed he lost a power amp because the subs lost some oomph.
Took the driver out to test, and found the coil former fell right out of the cone assembly. Looks like the epoxy joint failed.
No burned wires, no other obvious damage.
Anyone ever seen this, and could it be prevented?
