I am looking to upgrade to more powerful active speakers that can reach 200-300 people. I am currently considering the Behringer B215D, B615D, Mackie Thump 15 and JBL EON 615's. However, I am looking to see which is the most powerful in terms of wattage and decible's from a distance. I recently played at an outdoor event with 200+ people with 10" Rockville RPG10 (Obviously horrible speakers) and they just barely covered the area I wanted to. I was originally going to upgrade to the Behringer B215's, but they are only ranked at 550 watts PEAK, which I don't think will be loud enough. What i'm looking for is advice on powered speakers, and what would be the best bang for my buck.
