I do not use it myself, but have already had occasion to hear many times.
This is a subwoofer that is done (I think) to operate at multiple, in large or medium sized rooms or outdoors. I've heard in a small room, one on each side of the DJ, the sound was crap. Hyper Dry, serious not descendants at all.
However on large dance floors, coupled with several sides, and associated with the heads of the same brand, there is virtually perfect. Yield enormous, and its non Processed not aggressive at all.
