  • The MRX518S is a compact, high power subwoofer system containing a 2044G 457 mm (18") woofer in a front-loaded, vented enclosure. The enclosure is designed to present a minimum frontal area. The system offers complete input connection flexibility for compatibility with a variety of cabling schemes.
  • The input panel incorporates a pair of Neutrik® Speakon® NL-4 connectors wired in parallel. The MRX518S is supplied with pins +1/-1 connected to the woofer. This may be easily reconfigured to work with cabling systems intended to drive subwoofers on pins +2/-2. For "Subwoofer/Satellite" configurations, the MRX518S is equipped with a top-mounted, 36 mm pole mount socket that can receive the optional SS3-BK pole.

The enclosure is constructed of top quality plywood, coated in JBL's rugged DuraFlexT finish and is braced to maximize low-frequency performance. The attractive CNC-machined, 16-gauge steel grille is internally lined with an acoustically transparent screen to provide additional driver protection and give a very professional appearance.
