JBL PRX 518S Active Subwoofer

PRX 518S Active Subwoofer description:

The JBL PRX518S Powered PA Subwoofer 1 x 18 inch. Powerful and compact active subwoofer with Crown amplification.

The JBL PRX518S 18 inch Self-Powered Subwoofer System is compact and powerful, offering the performance of an 18 inch subwoofer in a package not much larger than a typical 15 inch sub. With a pole receptacle (that accepts a SS3-BK) on the top panel and integrated stereo pass-thru, with selectable HP filter, this is the perfect compliment to the JBL PRX500 full-range systems. Configured with a JBL PRX512M or JBL PRX515; the result is a highly transportable, high performance subsatellite system. The addition of a polarity reverse options further enables system optimization. The PRX518 is a high performance selfpowered compact subwoofer system. The PRX518S is comprised of a 2044E 460 mm (18 inch) VGC (Vented Gap Cooled) woofer driven by a Crown International Class-D digital power amplifier. A propriety DSP chip is at the core of a fully featured input section, providing user selectable crossover functionality, polarity optimization, protection, dynamic limiting and discrete component optimization. The enclosure is constructed of quality plywood and coated in JBL’s rugged DuraFlex finish. An integrated pole mount on the top enables an easy sub/satellite configuration. The CNC machined steel grille wraps around the sides of the enclosure so there are no protruding lips on the front of the box to create acoustical interference. The grille is also lined with an acoustically transparent foam to provide additional driver protection. The amplifier input panel offers stereo inputs with XLR or 1/4 inch jack compatibility. A user selectable crossover ensures a smooth transition to full-range system connected to the stereo outputs. Signal present and overload lights indicate the system status and assist in setting the optimum level, via the level control knob.
