Electro-Voice ETX-18SP 18" Powered Subwoofer, 1800W

Built for pro audio professionals who need authoritative, tunable low-frequency performance, the Electro-Voice ETX-18SP powered subwoofer delivers controlled, high-impact bass for live sound, installed AV and security monitoring applications. This pro subwoofer pairs an 18" DVX transducer with an 1800W Class-D amplifier and EV's FIR-Drive DSP to produce clean, accurate low end with up to 135 dB peak SPL and a usable bandwidth from 33–150 Hz. Integrated true-cardioid DSP presets reduce stage and microphone bleed for better monitoring and intelligibility — a major benefit in crowded venues and surveillance/command centers. The intuitive LCD and lock-out mode simplify calibration while preventing unauthorized changes in permanent installs. Durable plywood construction with EVCoat, removable casters and a combo pole cup streamline transport and deployment for touring rigs or fixed AV/security paging systems. Whether you’re outfitting a concert stage, a corporate auditorium, or a monitoring room that requires reliable low-frequency performance, the ETX-18SP brings precision, power and installation-grade security.
