Muscular, workhorse subwoofer for pros. Practical size and weight and a tuned, vented cabinet which throws in a cardioid pattern, making for a much tighter stage. At home on the road or as a permanent installation. They make a tidy cart/cover roll-around to go with. Long warrantee and good customer service. Industry leading technology.

I WANTED to hate this sub, I wanted it to be sub par, I wanted it to fail and sound like every other dual 12 out there. But holy mother of god this thing exceeded all of my expectations. When they said "3600 W" I thought they meant 900 rms, 3600 peak. I actually took the amplifier out of the sub and hooked it up to an amp dyno. Power to each of the cones (to 1% THD) is a solid 1200w with dynamic peaks up to 1800w per cone. So in reality the program power is about 2400w which is a LOT of power. The cardioid pattern is NO JOKE either, all of the bass energy is reflected forward. I had this sub set up at a gig (a rave in a 200 person room) under a table cloth paired with two qsc k12.2 tops (which I would also recommend) and one of my friends asked me what I was ... MoreI WANTED to hate this sub, I wanted it to be sub par, I wanted it to fail and sound like every other dual 12 out there.

When I showed him the one qsc his jaw just about hit the floor. I then had him step into the booth and he became further amazed at the lack of bass energy on stage. We could have a conversation without raising out voices at all. Cannot stress how good this sub is.

I bought one of this sub in 11/18 while playing It for about an hour it smells like a burnt iron and the limit light will trip on. I also had the gain at 12 0: clock my set up are as follows pioneer SZ2 and QSCk10.2 tops with one KS212c sub I also have 2 QSC KW181 and the limit light never trip on. I called QSC about the problem and they told me probably I am over driving the sub which I am not. I tried another Dj controller and the same thing happened I have to turn the gain on the back of the sub to 10:o clock for the sub not to limit
