Thanks, Scott. I'm located in South Point, OH. The very southern tip of Ohio on the Kentucky and WV border. I have definitely been scanning the local market and seeing a LOT of non-powered stuff. That's okay because I'd pull the trigger on that too, but the stuff seems really old and I can't make heads or tails of the quality. For example, these JBL subs: https://huntington.craigslist.org/msg/d/jbl-sr-2x15-trap-subs/6297125366.html. I came close to buying those last week, but I'm well aware there is a lot of worthless JBL stuff out there and I couldn't figure out which end of the spectrum these end up on. Same with other old used items, the specs aren't all widely available and without the speakers on review type sites it's hard for me to research.
Well hello there, fellow Tri-Stateian (Catlettsburg here) As far as that stuff on Craiglist, I know the guy that's selling his gear.. I'll talk to him and see if we can put you together a system, but don't count on it, trust me.
For metal in that small of a space, you would probably be better off just doing something strong for vocals, let the amps and drums run free.. maybe throw a little kick in if anything. Personally I like having more than enough.. if your budget is there, then I definitely would go with the JBL SRX800's for mains, and maybe the PRX800 for wedges (the SRX812P takes up too much space as a floor monitor IMHO)
My buddy owns a set of SRX815's and a bunch of SRX828's, so if you're interested we could set up a demo sometime when the stars align.
