I use it for night club events that play electronic music to an audience of up to 70 people, and and it seems to me like this sub was made for less bass heavy music, because it limits at a lower volume than what I expected. But as long as the volume is low enough, it sounds pretty good when I pair them with my 2x EV ELX 115p, and it has a built in low pass filter setting that is optimized for those speakers, so I didn't have to do much tweaking. And the app is very useful for adjusting the volume while I'm in the crowd.
In hindsight, I probably should have bought the 18 inch sub to avoid the limiting issue.
