P.A. bass bins

[frosty55]

Any suggestions for bass bins to partner a Behringer EP4000?

The most cost effective would be the Behringer B1800x. If you keep the limiters engaged in the amp the speakers keep on working.
I repaired a half blown system at a New York City Grenwich Village club that had the same combination and after I set it up with the limiters the DJs couldn't blow it up. I also put a Behringer compressor on the inputs before the EQs to keep the distortion down. The DJs will tend to push their mixer levels all the way up but there's nothing you can do about that.
