The JBL EON15 G2 boasts far more power than its predecessor with 300 watts of power dedicated to the low-end and 100 watts going to the high frequencies. The EON15 G2 performs powerfully and effeciently thanks to JBL's exclusive Thermomaster technology. This unique design uses a single cast aluminum baffle to draw heat away from heat producing elements. The heat then dissipates out of the finned ports thanks to the forced air created by the woofer.
