I use a GK 700rbII which is 480 watts @4 ohms. I have no need to play loud onstage as I have good PA support all the time. I play a 4 string bass and love the tone of my Avatar B210 cab which is rated at 500 watts. I actually like it better than my 212 which to me overpowers the b210 a little. So I am thinking of selling my B212 and replacing it w/ an Avatar 112, rated at 250 watts. That way I still have the lows, but not quite as much as the b212, and trade a 56 lb. cab for a 39lb. cab. I would probably never give either cab more than 200 watts. What do you guys think?
