There was a guy on here a while ago contemplating moving a Genz 600 head on for something bigger as it wasn't cutting the mustard with his 2x10 cab, I pointed out that my genz 300 head with a 2x12 would blow anything away that he puts through that 2x10 as the cab was the limiting factor, I said try it through a pair of 4x10s but he wasn't having it, more watts would have to be louder, I gave up in the end.
So what I'm saying is "why was my old 200 watt head and a pair of 4x12s louder than my 1000 watt head and a Barfaced one10?", speakers that's what's watt.
