Electro-Voice ETX-15SP - 15" (1,800 W) Active Subwoofer with FIR-Drive DSP and Cardioid Mode

The Electro-Voice ETX-15SP is a self-powered subwoofer module designed to reinforce the low frequency region of PA systems, specifically in conjunction with the full-range models of the ETX series . It features a 380 mm (15") DVX3159A woofer and a 1,800 W Class D amplifier with FIR-Drive , capable of delivering up to 134 dB SPL peak with fast, controlled response. The professional enclosure is constructed from 18 mm birch ply with EVCoat finish and a steel grille (16 AWG), and includes two handles and detachable wheels for easy transport. A combined pole cup (35 mm insert + M20 thread) is included on top for secure mounting of satellites.

The control panel offers DSP with LCD display and encoder for agile setup: presets by application and location (including cardioid mode for multi-sub arrays), selectable low-pass filter (80/100/120/150 Hz) optimized for matching with ETX tops, room EQ (1 band) , polarity switch and adjustable delay with a wide range for system alignment. With an operating range (-10 dB) of 32–180 Hz and a response (-3 dB) of 37–150 Hz , the ETX-15SP offers enough punch and extension for mobile events, rental, touring and fixed installation.
