JBL PRX 518S 18" Professional Self Powered Subwoofer System w/ Built-in CrownTM Amplifier, 0050036903172

Low-end punch!

Compact and powerful, the PRX518S offers the performance of an 18" subwoofer in a package not much larger than a typical 15" 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 PRX500 full-range systems. Configured with a PRX512M or 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 self-powered compact subwoofer system. The PRX518S is comprised of a 2044E 460 mm (18") 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
