Reply to New Club Owner looking for speaker help

I'm trying to design my DJ setup and its killing me. I'm no sound guy and the locals in my area are worthless.

My Club will average around 300 people and max out at 700. I'm looking for a simple system with a lot of power. The SQ FT of the room is around 2500 sq ft.I believe I can figure out my mixer, laptop, and all of that setup. I'm having a hard time deciding between amps and passive woofers vs active woofers. I see a lot DJs in my area using Cerwin Vega passive woofers. I was searching online and seen good reviews on the QSC KW181 and the JBL PRX618S-XLF Active Woofers. Which direction would you go in? I'm really looking for some serious bass
