The JBL Eon 315 is a lower powered version of the Eon 515. At 280w output (per speaker), a pair of these will still be more than adequate for bands doing small to medium sized venues. The 15" driver will cope with pretty much anything, but you'll need to add the bass bin if you want to start mic'ing drums.

Here's what JBL say about the Eon 315 
 

The EON315 is a 15-inch, two-way, powered, portable speaker system. It is a complete self contained sound reinforcement system, capable of full-bandwidth reproduction at high levels with the added benefit of a microphone pre-amp enabling the direct connection of a dynamic microphone. The EON315 is comprised of a 380 mm (15 in) JBL woofer, a 25.4 mm (1 in) neodymium high frequency compression driver coupled to a 100 H by 60 V waveguide. Both components are driven by the discrete channels of a 280 watt Class-D integrated power amplifier. The input section contains all cross-over functions, protection, and system EQ functionality.
