The PRV Audio 15W700 15" professional audio woofer is designed to be a perfect drop-in replacement for many popular PA speaker cabinets and works equally well in ported or sealed cabinets. A ribbed paper cone is employed to give you the classic tone associated with many high-end speakers.
Moving to the motor, you'll find features not normally associated with other drivers at this price point: a 3" diameter voice coil with a Kapton® former and 5.5 mm of Xmax, 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.
