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 an extremely low Qts of 0.32, making the 18FH2400 the ideal candidate for your horn-loaded subwoofer design.

Rated 5 out of 5 by from Very Good Sub Very EconomicThis Sub was used as replacements inside Cerwin Vega Folded Horn boxes Lines up perfectly Sound was very Monstrous in the box and Handles Power very well. When I got the sub out the box on the magnet it say 1200 watts Rms 2400 watts Continous 4800 Peak...... I am a bit concerned about the fact there is no recoil kit but if its true what the magnet says then i dont have a worry about that.

I will be putting this speaker in a JBL MRX528s, It is a ported box. The watts are the same as the 2044-h, but frequency responses are different. Will this effect the way this sub operates, shorten its life? I have my xover set at 40hz - 85hz for my subs.

ive got a cerwin vegan 18 in folded horn bass bin and just wondering how well they would go together but also my cutout diameter is at 16.56" is that going to be an issue if this sub is 16.2"?

Asked by: JOshh
This will work in a horn type enclosure. The cutout will also be ok although you may need to drill new mounting holes.
