Electro-Voice ETX-18SP 18" Active PA Subwoofer

Designed for discerning audiophiles, the ETX-18SP delivers a highly linear response across an extended frequency range, enabling powerful low-frequency reproduction from its 18” woofer. This ensures exceptional bass performance and maintains audio clarity even at maximum sound pressure levels of 135dB.

The system offers consistent coverage throughout the audience area. Its patented waveguide provides uniform bandwidth response and ultra-wide dispersion, ensuring detailed sound is experienced from all locations—front, sides, or back. Positioned at the front of the enclosure, the waveguide reduces latency correction, contributing to reliable and smooth audio in every application. The ETX-18SP sets a new standard for live sound reinforcement.

Installation and operation are straightforward with the integrated DSP, which includes presets for various speaker applications, crossover frequencies, and top/sub configurations. Boundary compensation filters enable consistent sonic performance whether the unit is deployed as a floor monitor, on a tripod, or in a suspended setup. Further sound customization is available through adjustable delay, a three-band EQ, and advanced high-crossover points, offering control options not commonly found in comparable loudspeakers.
