Lot's of different options, and it sounds like you've determined what size of setup you want. If your going to be doing small party's, I would recommend two powered speakers, since you already have the tables and mixer. And the powered speakers will help in the ease of setup also. If you can find them, there still may be some out there in Best Buy, but they are discontinued, I would look into getting two Thump15's by Tapco. They put out alot of volume and would be great for a DJ setup. And obviously you could upgrade from that to Mackies, or EV's. Just depends on the price range. Please give us a call if you have any more questions. Thanks! Randy Smith M.I. sup Tempe, AZ 480.303.7251
