As indicated in the title, is subwoofer is simply outstanding. SERTE it is not the height of a CPA, but it goes far beyond Martin Audio, Turbosound and many other yet so well known.
This sub simply worth every penny.
I recommend it to all of his passion.
I do not own but leases it when I need it, I can with my two head SP530V5 LSS (I generally use only) to fill a room of 1,000 people.
