Ok, so here's the deal. My PA does fairly well considering the medium venues that we use it in. We're playing in a bigger auditorium later in the year, though, and we're worried that our existing PA might not provide that punch that the room requires. For that matter, I've been wanting to upgrade to some subwoofers for a while. I like to be able to provide a little punch in the chest, you know what I mean? Money is tight, as is storage room. So ultimately, we're looking for something relatively compact and inexpensive. FWIW, we're running 1500W into 4 500W main cabs - two of which are 4x12 mains and are carrying the bulk of the bass response right now. Like I said, they work well for the venues we play most of the time, but we're running very near the peak of what we can expect out of them. Has anybody had any experience with the Peavey PR subs or the Behringer 18" subs? I figured I'd pick up a Behringer EP2500 and bridge it to push whatever sub (or subs) I end up getting. Otherwise, I'll swap the Behr amp into my PA mains and use my QSC 1450 bridged for the subs, but I'd rather keep the better amp pushing important things like vocals and such. I dunno. Any ideas? The big gig is in October, but we might have some other large gigs pop up this summer, so I'd like to be shopping and saving while we can. Let's set budget at $1000 or less. Go.
