I've been searching high and low for some info about minimum wattage for bass cabs. I have a newly refurbished fender bassman 50w tube head, and I'm trying to find the right cabinet for it (it'll be my living room rig). I've heard that underpowering your cabinet can damage it over time. So how do I choose the right cab size? I'm thinking of 2X10 set-up-possibly a fender pro 2X10, but maybe an Avatar. Problem is, I can't even start to choose 'till I know what size I should be looking for, and everything out there shows max wattage not minimum. Any suggestions?
