Not really sure where to post this, or even how to ask the question, but I was wondering if drummers ever have their own amplification system (like a PA to amplify just the drums, instead of running through the general PA)? The reason I ask is that I'm thinking of trying my hand at building some kit-based PA speakers, and for my first attempt I was thinking of building something that my son could use in his band. Their PA is OK, but it really doesn't to a whole lot for the kick drum, and their amplifier can't handle subs in addition to the mains. I was thinking that I could pick up an amp, and build a speaker(s) to amplify the drums alone, and their existing PA could then handle vocals and guitars alone. Would this work? Does anyone do this?
