I currently run a 220W solid state head(Crate BXH220) into a Crate BX810e cab. Even when using just stage volume, I never have the volume above half crank and I've always gotten complaints that I'm too loud in the mix(average of 120 people crowds). I mainly go through the PA. I've seen people using Yamaha CP2000 or QSC RMX1450 amps for medium gigs. Is it just the headroom? Or do you actually use that much power? It's almost confusing me of what to get for a power amp for my next rig(pair of Avatar B112s once the front port ones are available). I know I'll be using the Crate for a while though. Just a thought. and something I've been curious about for a while.
