The JBL EON315 Portable Self-Powered 15" Two-Way Speaker is a 15-inch, two-way, powered, portable speaker system, perfect for a crisp sounding speaker wherever your gig takes you. 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 100Â° H by 60Â° 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.
