The 18FH2400V2 18" subwoofer, from PRV Audio, is purpose-built for use in folded horn subwoofer enclosures, but also features 10 mm of Xmax a qts of 0.48 for use in vented cabinets. A rugged six-spoke, cast aluminum frame is used for rigidity and minimum back wave reflection. The large diameter spider is combined with an accordion surround to keep the cone travel uniform throughout the driver's stroke.
The high 1,200 watt power handling is achieved with the 4" voice coil that is cooled by the vented pole piece, gap vents, and frame venting. A high BL magnet assembly saturates the motor structure for a Qts of 0.48, making the 18FH2400V2 the ideal candidate for your horn-loaded subwoofer design.
