The MRX518S is a compact, high-power subwoofer containing a 2044G 18" woofer in a front-loaded, vented enclosure. The speaker 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 audio speaker is equipped with a top-mounted, 36mm polemount socket that can receive the optional SS3-BK pole. This can be used to mount speakers equipped with standard 35mm pole sockets and weighing up to 100 lbs. The enclosure is constructed of top-quality plywood, coated in JBL's rugged DuraFlex finish, and 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.
