The black Electro-Voice ELX200-12SP-US is a 12 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 a 12 woofer to produce a frequency range of 41 to 165 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.
