I'm currently running a TerrorBass 500 into two Acoustic 4x10mkIIs. I've noticed a serious lack of bottom end. It cuts through ok seeing as we only have one guitar player and we play standard tuning radio friendly rock. However, it seems to lack some booty. Even if I boost the lows, there is just never the table shaking bass that I feel should be there. So basically, I need some cabinet suggestions. HELP ME.. I don't want to just keep buying cabs until I'm happy. Somebody has have to have a good suggestion or two.
