Tour tested Differential Drive technology delivers extended frequency response, high power output and low distortion in a dramatically lighter package. With the ferrite magnet positioned inside the dual-coil/dual-gap voice coil, heavy steel pole pieces are eliminated. The heat sink is the chassis itself, further lowering system weight while ensuring consistent, reliable performance.
Highly efficient Class-D amplification drives Maximum Sound Pressure Levels are the best indication of the performance of a powered speaker and all PRX700 Series excel in this critical specification. JBL’s ability to maximize the speaker and amplifier performance guarantees ample power, accurate dynamics and sonic purity.
Road Tough Construction
Built from a combination of 25 mm (on the top and bottom for added rigidity) and 18 mm, strong, light-weight poplar plywood made structurally sound with tongue and groove joints. JBL’s tour proven DuraFlex finish, grilles from dent-resistant 16 gauge steel, and light-weight glass-filled nylon handles ensure strength and durability.
The PRX700 Series is a platform technology with a range of models that integrate seamlessly for multiple system options that excel in challenging audio environments and loud volumes. Compact and powerful, the JBL PRX718XLF offers exceptional sub/sat performance for its weight and size.
- Pole receptacle accepts a SS3-BK or SS3-BK24 on the top panel
- Integrated stereo pass-thru, with selectable HP filter, and polarity reverse
