The PRX618S 18" Portable Subwoofer is a high-performance powered compact subwoofer system. The PRX618S is comprised of a 268G 460mm (18") Differential Drive dual voice-coil and magnetic gap, neodymium woofer driven by a Crown Class-D power amplifier. The amplifier input panel offers stereo or mono line level inputs via balanced XLR connectors as well as a single channel speaker level input via a 1/4" TS phone jack. Signal processing, crossover functionality and limiting for the system is integrated into the input section functionality. Overall subwoofer input sensitivity is controlled by a single easy grip knob and a simple switch enables polarity reversal for sub/satellite system optimization. Signal present and limit lights indicate performance status.
Compact and powerful, the PRX618S 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 or SS3-BK24) on the top panel and integrated stereo pass-thru, with selectable HP filter, this is the perfect compliment to the PRX600 full-range systems. Configured with a PRX612M or PRX615M the result is a highly transportable, high-performance subs/satellite system. The addition of polarity reverse options further enables integration with any top cabinet.
All PRX600 cabinets are built from a combination of 1" (25mm) on the top and bottom for added rigidity, and 3/4" (18mm), strong, lightweight poplar plywood made structurally sound with tongue and groove joints. All PRX600 Series cabinets are protected by JBL's tour-proven DuraFlex finish. Grilles are made from dent-resistant 16-gauge steel and handles are made from lightweight glass-filled nylon for added strength and durability.
PRX600s have been certified "Green Edge" compliant by Harman Professional.
SPECIAL NOTE: JBL highly recommends that no more than 70 lb. of weight be placed on a speaker pole that is mounted to a PRX618S or PRX618S-XLF.
