The EV1813M is a powered home theater subwoofer in a vented, ported enclosure. It uses a single front-firing 18-inch neodymium woofer from B&C in Italy, developed exclusively for Power Sound Audio. The woofer has a dual voice coil motor design.
A built-in ICEpower amplifier delivers 1920W RMS (4300W peak). A DSP-based feature board provides the controls for integrating the subwoofer into a system: gain, time delay (phase), crossover and room size. The amplifier has left and right RCA and XLR inputs and a 12V trigger.
The enclosure is heavily braced, CNC machined MDF with a non-reflective matte black finish. An acoustically transparent fabric grille covers the driver. The amplifier is mounted on the rear baffle, and a slot port design provides extension and laminar air flow.
