EKX-18SP features high-efficiency Class-D power amplifiers (up to 1300 W) with integrated QuickSmartDSP, and delivers up to 134 dB SPL utilizing high-sensitivity transducers designed and engineered by EV (18-inch EVS-18C subwoofer). The EKX amplifier incorporates intelligent thermal management (with a variable-speed fan controlled by multiple onboard sensors) which ensures superior performance and reliability in demanding environmental conditions. Powered subwoofer models allow easy setup via three (3) presets (Music, Live, Club), sub/top system-match crossovers, five (5) user-programmable presets (Store and Recall settings), visual monitoring of limiter status, input level meters, and master volume control to ensure optimal gain structure. Adapted from our touring systems, EV’s exclusive Cardioid Control Technology allows output to be steered towards the audience with up to 35 dB reduction on stage when multiple subs are deployed.
