Hi, I did a gig last night that turned to shit, half way through someone decided to spray a chemical fire hydrant inside right above where i was setup and im pretty sure it fucked my speakers up and on top of that i had the three speakers running off one powerboard with lasers, laptop etc plugged into the same socket, anyways the speakers are 15" powered audioline's. The Horns on them still work perfectly but i dont get any output from the subs. Are the subs blown or is this just a minor problem that i can fix?
