I took out my new rig for the first time last night. It was in a scenario which is probably the loudest that I need to be with 2 loud guitarists and a mic'd drummer. I have a Superfly with (2) Yamaha BBT110s cabs. I was barely loud enough with the volume on 8. The amp is rated at 2x250 and I run a Yamaha 4 ohm cab on each side. I love the tone and flexibility of the amp but was wondering if the issue was just having the (2) 10" speakers. Would I see a increase with switching to 2x10 and a 12 or more efficient speakers.
