My vote in this category (<$1000) is for the RCF J series. I previously had the Evox 8 in wood but the newer, cheaper, plastic J series definitely has more bass. It's important to note, I have found that with prerecorded music from a DJ controller into a line mixer that the entire Evox line are best run with the gain dial all the way up - assuming proper gain structure elsewhere in the system.
Looking at the Peavey, EV, Turbosound & Maui, offerings in this category I prefer the universal threaded speaker pole and Speakon cable of the RCF. The fewer propriety parts the better.
