Purposeful product design Enclosure designs have been optimized for ideal acoustic resonance taking advantage of injection molding techniques and mechanical shaping of the enclosures. This results in tremendous increases in cabinet volumes which enable better acoustic performance while maintaining the same footprint. Two intelligently positioned handles make the 600 easy to carry and move around. Integrated hardware mounts, designed into the enclosures, allow each model to be flown when required. And indexed feet molded into the enclosures allow for convenient storage and transport, secure stacking for stage monitor and traditional stand up configurations, and unique acoustic configurations. JBL waveguide technology The EON615's extraordinary performance results from a breakthrough approach to waveguide design. JBL engineers examined the radiation characteristics of the EON's high and low frequency drivers at 36 different points employing JBL's exclusive, state of the art measurement techniques, then designed the Image Control Waveguide ensuring the sound radiation and coverage pattern match at the high frequencies, the crossover point and the low frequencies. The result is consistent response throughout its 110 degree coverage pattern. The quality and consistency between on axis and off axis response delivers uniform coverage and high intelligibility throughout the coverage area, which means the EON615's smooth, transparent sound is the same for the entire audience. Bluetooth integration Knowing that fine tuning your sound needs sophisticated yet convenient control, JBL engineers developed an iOS and Android supported Bluetooth v4.0 compliant interface for controlling master volume, adjusting the 5-way, user definable parametric EQ, and saving and recalling user presets.
