I've been playing a mighty, bumblebee loaded 1980 G&L bass through my valve guitar amp with 2 x 12" speakers. I'm not cranking it or anything to be on the safe side. Still the 2 weber alnicos don't show the whole low end spectrum as they weren't designed for bass anyway but my question is... the speakers are very new and still sound a bit stiff... would the low end freqs coming from the bass at low volume help loose those speakers up?
