I've been using a pair of EV ZLX12P for weddings, corporate functions and the odd house party/gig.....they are reasonably priced and punch way above their weight (they've been compared to QCS K12s). Probably the best specs in their price range. Don't take my word for it. read the reviews and give them a listen. I think you'll be pleasantly surprised.
