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.

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.

I have had mine for almost a year now and I love it. They hit so hard without even pushing them to the limits. I have only broke 2 mirrors with this. I am constantly adding to the playlist of songs that I want to hear with this cause of the deep base it puts out.

Great sub. It's large and powerful. Extremely loud. Not ideal of mobile DJ's. If you have a crew for setup this sub wouldn't be Hard to setup. But it does way a lot . Over all I give this a full 5 stars.
