This large, heavy sub is quite powerful. It's an extended frequency model compared to most PA subs. The response is not deep compared to high-end home audio subs that can hit 20hz at -3dB such as HSU and SVS subs (such as used for movies) but that’s unnecessary or wanted for live sound.

UNBELIEVABLE BASS RESPONSE! Does not break a sweat when cranked up. Stays cool all night. Cannot ask for a better sub. Just buy it.

This thing is bad to the bone. Nothing but clean very deep bass. Can't wait to take it to a gig. It is heavy but nothing I can't manage with a hand truck.
