hey fellas, i'm using a pod hd500 and im trying to find a PA speaker (or alternative) that can compete with a cranked half stack, bass, and heavy hitting drummer. i've tried out the several pa speakers that sounded great but i doubt it'd be loud enough without peaking at a loud practice. i've tried the alto ts112 and 115, mackie hd1221, and mackie srm550 and i'm pushing them right to the point of clipping to get the appropriate volume. it'd be nice to have some spare volume so im not driving the hell out of the speakers at all times. anybody have any suggestions? cheers!
