Product Details

PRV Audio 18FH2400 18" Folded Horn Pro Audio Subwoofer 8 Ohm

The 18FH2400 18" subwoofer, from PRV Audio, is purpose-built for use in folded horn subwoofer enclosures, but also features 7 mm of Xmax for use in vented bass reflex cabinets. A unique four-spoke, cast aluminum frame is used for rigidity and minimum backwave reflection. Dual spiders are combined with an M-Roll surround to keep the cone travel uniform throughout the driver's stroke. 

A high 1,200 watt power handling is achieved with the 4" voice coil that is cooled by the ported pole piece, and cone geometry is maintained by a layer of non-pressed paper on the underside. A high BL magnet assembly saturates the motor structure for a Qts of 0.35, making the 18FH2400 the ideal candidate for your horn-loaded subwoofer design.
