JBL PRX718XLF

The JBL PRX718XLF is an 18" 1500-watt powered active extended low frequency subwoofer system. The PRX718XLF is the next step in the highly successful PRX Series and introduces the first use of JBL’s patented Differential Drive® Technology with ferrite drivers. Differential Drive technology incorporates lower mass in the ferrite magnet for reduced weight while maximizing power amp efficiency for greater heat dissipation and increased power handling.

Powering the PRX718XLF is a 1500 Watt high performance, exceptionally low distortion biamplification system engineered to deliver clean power with maximum headroom to efficiently deliver rich, deep bass response even at very high sound power levels. Compact, ultra lightweight, the PRX718XLF uses JBL’s tour tested technology throughout so you can trust it to deliver a lifetime of reliable performance.

The tested Differential Drive™ technology delivers extended frequency response, high power output and low distortion in a dramatically lighter package. With the ferrite magnet positioned inside the dual-coil/dual-gap voice coil, heavy steel pole pieces are eliminated. The heat sink is the chassis itself, further lowering system weight while ensuring consistent, reliable performance.

Road tough construction: built from a combination of 25 mm (on the top and bottom for added rigidity) and 18 mm, strong, light-weight poplar plywood made structurally sound with tongue and groove joints. JBL’s tour proven DuraFlex™ finish, grilles from dent-resistant 16 gauge steel, and light-weight glass-filled nylon handles ensure strength and durability. All M10 suspension points are constructed from 14 gauge steel and have been tested with a yield-strength of 1000 lbs. each. A seriously rugged package that will withstand the brutality of constant road use.

The highly efficient Class-D amplification drives Maximum Sound Pressure Levels are the best indication of the performance of a powered speaker and all PRX700 Series excel in this critical specification. JBL’s ability to maximize the speaker and amplifier performance guarantees ample power, accurate dynamics and sonic purity.

The PRX700 Series is a platform technology with a full range of models that integrate seamlessly to create multiple system options that excel in challenging audio environments with loud volumes. excel in challenging audio environments and loud volumes. The PRX718XLF provides accurate, powerful sub-bass frequencies for sub/sat systems.
