The MRX528S is a compact, portable high-power subwoofer with dual 2044H 18" woofers in a front-loaded, vented enclosure. The enclosure is designed to present a minimum frontal area. It is also configured in an upright format to permit the convenient stacking of full-range enclosures on top without the need for an additional pole. 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 MRX528S 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. The enclosure is constructed of quality plywood, coated in JBL's rugged DuraFlex 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.
