Hey guys, I recently bought some RTR EXP-12 speakers. They’ve been sounding great so far. When I try to push em a little louder, the L pad on the back starts resonating on certain bass notes (which happens on a number of techno LP’s I play). It’s not a huge problem, as they’re loud enough even when it’s not happening. However, when I do want to push them, it gets a little jarring hearing that buzz. Is there anything I can do about it short of removing the L pad? Thanks.
