I'm waiting to hear back from Bernie at BLT Sound, but in the meantime, thought I'd ask about this on TB to see if anyone has encountered this. Yesterday, I installed an Eminence Deltalite II 2512 12" driver in a cabinet to replace a Delta 12 LFA. I handled the driver with great care, connected the wires properly, then tightened in all screws carefully. So far, so good. When I connected things up and starting playing, I am hearing a buzzing. The notes are coming through the Deltalite fine, though. The buzzing was in the background, but persisted until the notes had nearly died out. Same thing happened with different basses and heads. I'm pretty sure it isn't because the speaker needs breaking in, because I bought a CH-2010 10" a while back, and it sounded good out of the box- no buzz. Has anybody encountered this? Could this be shipping damage? Thoughts?
