Product Details

PRV Audio 18SW1800 18" High Power PA Subwoofer 8 Ohm

The PRV Audio 18SW1800 18" professional audio subwoofer is designed to be a perfect drop-in replacement for many popular PA subwoofer speaker cabinets and works equally well in ported or horn-loaded cabinets. In the motor, you'll find features not normally associated with other drivers at this price point: a 4" diameter voice coil with a Kapton® former and 5 mm of Xmax, relatively high sensitivity, and a fairly low free-air resonance that allows this driver to play down below 40 Hertz. A specially designed resin was been applied to the woven spider for increased longevity, and the cloth accordion surround ensures smooth, accurate sound.

A non-pressed pulp cone offers a natural classic tone found in most high-end PA speaker cabinets, making the 18W1800 driver an ideal replacement woofer or subwoofer in both ported and sealed speakers. A special compound is incorporated into the the woven cotton surround to resist against wear for years of use. Spring-loaded speaker terminals make quick connection a breeze.
