I purchased an Ampeg 410 HLF cabinet and a GK 400 RB-IV amp just over a year ago, and I've just blown a speaker for the second time in just over a year. Right after I picked up the rig, I used it for recording in a home studio. The engineer really cranked the amp to get a huge sound that shook the whole house. It sounds great on record, but I have a sneaking suspicion that that shortened the life of my speakers considerably. Is it possible that the damage done almost a year ago could be just cropping up now? Or is it something else I'm doing wrong? I've been playing bass for over a decade, but I'm still remarkably ignorant when it comes to technical stuff, so any help you can provide would be great.
