The PRX618S-XLF, extended low frequency subwoofer was designed and engineered to provide sub bass frequencies with accuracy and power. Used as a single sub in a sub/sat system or in multiples as part of a scalable, large format sound reinforcement system, the PRX618S-XLF performs with extreme efficiency and control.
The PRX618S-XLF is a high performance self-powered subwoofer system. The PRX618S-XLF is comprised of a powerful 2268FF Differential Drive dual voice-coil and magnetic gap, neodymium woofer driven by a 1000 Watt (dual 500 watt) Crown Class-D power amplifier. Dual-Bridge Technology directly links discrete amplifier channel outputs to each voice coil in the Differential Drive woofer. Electrical power transfer to the transducer is optimized for more power performance. A proprietary DSP chip is at the core of a fully featured input section, providing user selectable cross-over functionality, polarity optimization, protection, dynamic limiting and discrete component optimization.
The amplifier input panel offers stereo inputs with XLR or 1/4-inch jack compatibility. A user selectable crossover ensures a smooth transition to full-range system connected to the stereo outputs. Signal present and limiter lights indicate the system status and assist in setting the optimum level, via the level control knob.
All PRX600 cabinets are built from a combination of 25mm (on the top and bottom for added rigidity) and 18mm, strong, light-weight 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 light-weight glass-filled nylon for added strength and durability.
JBL highly recommends that no more than 70 pounds of weight be placed on a speaker pole that is mounted to a PRX618S-XLF.
JBL's history is rooted in that of its namesake and founder, James B. Lansing. A true pioneer in Professional sound technology, Lansing developed many processes and products from the earliest motion picture sound systems in the 1930s to some of the first drivers in Leo Fender's guitar amps in the mid 1940s.
Today, JBL produces a wide variety of audio equipment, from consumer electronics to portable loudspeakers and subwoofers to high-end installed line arrays. Their commitment to innovative design is evident in everything they produce, with an emphasis on affordable, reliable gear for the working musician.
