JBL EON518S/230 18" Self-Powered Compact Subwoofer, 42Hz-100Hz Frequency Response, 230V

The JBL EON 518S is an 18-inch, direct radiating, high performance powered compact subwoofer system. Designed to extend low frequency performance of any EON system. It also offers the convenience of an integrated crossover and stereo loop-thru capability. The EON518S is comprised of a 460 mm (18") Differential Drive woofer is driven by a 500 watt Class-D digital amplifier. 

The amplifier input panel offers stereo or mono line level inputs via balanced XLR connectors as well as a single-channel speaker level input via a ¼" TS phone jack. Signal processing, crossover functionality and limiting for the system is integrated into the input section functionality. Overall, subwoofer input sensitivity is controlled by a single easy grip knob and a simple switch enables polarity reversal for sub/satellite system optimization. Signal present and limit lights indicate performance status. An additional switch is provided to defeat the illuminated logo in theatre applications. 

The enclosure has been engineered for maximum performance and absolute minimum size. Constructed of 18 mm plywood, it is coated in JBL's rugged DuraFlex finish. It also features a full screen-backed steel grille designed into a rugged copolymer bezel for maximum component protection. For comfortable portability, the EON518S features two large ergonomic rubber grip handles.
