Last night at a gig the sound guy came up to me after the first set and says "Man, I love that cabinet." It's an Ampeg PR-something-or-other with an 18, 2x10's, 2x6's and HF driver. He shook his head at my amp (Peavey Nitrobass) and proceeded to tell me that I am damaging the voice coils because the cabinet isn't getting enough power. Frankly speaking, this sounds absolutely ridiculous. I can't take the amp past 4 and expect to hear the guitarist. My sound is clear, bright and thumpy. I can understand the potential of speaker damage if the signal was extremely over-driven and distorted pushing through the speaks at high volume, but I think the guy just doesn't know what he's talking about. I liken the argument to putting a Suzuki motor (the head) into a HumVee (the cabinet). The motor will eventually blow up but the Hummer will be fine. Who's right? Is there something I am missing here?
