General
The PRX718XLF is a compact, yet very powerful 18-inch subwoofer with bass-reflex technology and a built-in amplifier. Its crossover frequency is 30 Hz (-10 dB) and its maximum pressure level is 134 dB. In addition to a 1,500W amplifier, the digital amp module contains a DSP with all controller functions as well as a stereo crossover with 24 dB incline. Moreover, the PRX718XLF features a 180-degree phase switch and stereo outputs with switchable high-pass filters that allow you to connect top speakers like the PRX725 and PRX735 or satellite speakers like the PRX710, PRX712 and PRX715 directly to this subwoofer.
Immense power in a rugged housing
The PRX718XLF owes its relatively light weight of 36.8 kg to the specially designed Dual Coil Drive (DCD) woofer and the very efficient digital class-D power-amp circuit. Despite its light weight, this subwoofer is able to produce an immensely high continuous output of 1,500 watts. The sub's rectangular housing is made of sturdy plywood and covered with JBL's rugged Duraflex lacquer. There's a countersunk M20 threaded pole socket on the top for a distance rod to mount a top cabinet on. The grill is made of powder-coated steel and features an acoustically transparent fabric on the inside.
