This is a marvelous invention. If you always wanted the effect and directivity of a limited line-array but only had money for conventional 2-3 way speakers, this is the perfect compromise. All you need is a good stand (or a heavy subwoofer with a pole, for that matter) and you can point the top speakers at an angle, to the ring floor and no longer horizontally, above the heads of your audience.
No more wasted power to the back of the room where no one cares about the band/DJ playing. This has multiple advantages: less mic feedback, less unwanted reverb, a more directional sound which means, in turn, higher volumes on the ring floor and less music in the rest of the room.(for those of us who just want to have a conversation). All in all, a great product. I definitely recommend it as I use it with my JBL PRX 735 with good results.
