With a pole receptacle that accepts a SS4-BK or SS4-BK24 on the top panel and integrated stereo pass-thru, this is the most powerful low-frequency complement to the PRX full-range systems. The addition of a polarity reverse option further enables system optimization. The low frequency driver used is the 2268FF 18" which has been used on many JBL subds in the past. It's a good sounding Neodymium speaker which is powered by a 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 custom 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. It's almost like having a mini Driverack system inside the sub itself.
The actual PRX618S-XLF cabinet is 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.
All in all, the PRX618XLF is a great lightweight sub Call or email RMC today to order yours.
