Gut-pounding bass

You'll add real impact to your performance when you add a JBL PRX718XLF subwoofer or two to your PA system. A single PRX718XLF powered sub delivers up to 1,500 watts to its 18" woofer, producing 134 dB of sound pressure — that's enough power to fill a small club or auditorium with wall-shaking bass. If you're a church performer, a working band, or a DJ, you can create a compact full-range PA system capable of handling medium-sized clubs and venues by adding a pair of these powerful subs to a set of PRX710, PRX712, or PRX715 powered speakers.

Rugged road-tested components

The 18" low-frequency driver in the PRX718XLF is the same one that JBL uses in its top-of-the-line concert arrays. This Differential Drive® subwoofer puts out high-powered bass with low distortion, having proven its toughness on the road by standing up to years of touring.  A built-in dynamic limiter by dbx ensures that an unexpected overload won't damage the sub.

JBL used tongue-and-groove construction to build this solid poplar enclosure, then coated it with their tough DuraFlex™ finish. You can be sure this sub will survive the normal bumps and bangs of life on the road and play reliably on the job every night. The enclosure even features a pole socket so you can mount your mid/high PA speaker above the sub on a standard speaker pole, for a smaller onstage footprint and better audience coverage.
