oops...see all you have is a non powered mixer...sorry 'bout that. Not sure how big of a club you're doing. But i'd try these, light, great reviews, and great customer service. Which is so important.

I current run 4 front of house speakers. 2 Carvin LM15 two ways, and 2 LM153 three ways. I traded out the standard neo's, and loaded mine with 15" kappalites. The stock speakers are also good in these. They are built by B&C a top shelf italian speaker manufacture. I just happen to prefer a cast fram transducer is all, like the kappalites. Good Luck. George
