JBL MRX528S Dual 18" Bass Reflex Subwoofer, 40-250Hz Frequency Response, 4 Ohms Impedance, 97dB Nominal Sensitivity

The JBL MRX528S is a compact, high-power subwoofer system, which contains dual 2044H 457 mm (18") woofer 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 JBL 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.
