I have to say, I was not expecting this system to do so well. I am absolutely astounded at the quality of this line array system. Combine 4 of these units with a sub on top, hang them on either side of your venue and get ready to experience a loud and clean sound. I frequently work with dance groups using our venue and they never complain about the volume and I still have quite some room left on the fader. Those speakers produce crisp highs and have great low end response. One of the huge pluses for me at least is the fact that these units are powered. No more bulky amps clogging up your rack turning your work area into a mini furnace and a mess of wires!
