Oh yes, SQ, the pinnacle of SQ... but so much more. Hands down the loudest subs ever made... and they get loud while maintaining pristine sound quality.
I would be afraid to run more than one... I can't afford to replace all the glass in my Jeep.
At the competition I went to a guy was running one and he won every class, sq and spl, and never even had to turn it on because everyone else bowed out gracefully in imminate defeat....... Never seen anything like it.
Truth be told there has yet to be an amp or combination of amps that could use the full potential of this sub it would take approximately 2 nuclear power plants to provide adequate power.
These things have the most sought after motors in history. I once replaced the motors on a pair of Solo X 18's with the motors from the PUPS. I gained 6db! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
Bro you can't just going around selling weapons of mass destruction like this... Everybody within a 50 mile radius could go deaf if these fell into the wrong hands
