Price is right to get you some fairly OK self powered 15" PA speakers...sound is so subjective, I'd say just hit up a Store DJ/Sound and lighting place with some of your fav tracks loaded up on your phone ready to play and have a listen to what's on offer.

Plenty of options on that price range, but you'll never know which ones you personally like until you get in there and hear them
Pete Gordon - Deep and Low

Slower tempo but still with balls, deephouse, slow-mo, futurehouse, nudeep, indie, nudisco, hints of progressive, whatever the fuck you want to call it, just good shit! Get on it
