Overview The black Electro-Voice ELX200-18SP-US is an 18” 1200W powered subwoofer designed to provide dependable low-frequency amplification, easy installation, and convenient control for sound engineers and performers in live stage applications, theaters, DJ setups, and mobile rigs. It features 1200W of Class-D amplification, which drives an 18” woofer to produce a frequency range of 40 to 145 Hz. Route a balanced source such as a stereo mixer output via two XLR-1/4” combo jack inputs, then utilize the two XLR Link outputs to connect to full-range speakers. A rear-panel knob and LCD allow access to master volume and the on-board DSP functions, which include three easy-setup presets, five user-programmable presets, adjustable low-pass frequency, and metering. Adjust parameters via the single-knob interface and LCD, or control the subwoofer via Bluetooth.
