Ehh, Depends on what you're doing with it
I have two of these, needed a small, more compact set up. Previously, i used one for a drum monitor, and for small dj gig's.. I bought another one thinking that two would hold up in a live band foh situation. No, just no. With about 40 people on the dance floor it couldn't throw a kick and can't have much bass guitar in the foh with these.. the bass players 300w amp was louder, deeper.. I use ONE LS801p usually, I realize its a different monster, but with all the specs and power ratings, I thought two DXS12's would come somewhat close... I was dead wrong.
In summary, great sub for small dj applications, power acoustic acts, fantastic Drum sub.. but for FOH, don't use it. Get EV, or jbl 15's for lighter/compact applications.
