Active subwoofer with unprecedented power.

Ultra deep low-end reinforcement is what the JBL PRX718XLF 18" powered subwoofer delivers in spades thanks to its 1500 watts of Class D power. JBL's Differential Drive technology incorporates lower mass in the ferrite magnet for reduced weight while maximizing power amp efficiency for greater heat dissipation and increased power handling. The clarity of this enclosure relative to its volume is simply revolutionary. The PRX718XLF punches above its weight class with its strong and clean lows.

The PRX700 Series represents an evolutionary step in powered speaker design. Efficient amplifier power, rugged durability and enhanced versatility combine together in a self-powered loudspeaker designed from the ground up to perform in the real world of sound reinforcement. Inconvenient audio environments, high ambient noise levels and loud volumes are typical features of performing, and the PRX700 series is adept at meeting all of these challenges. They are the first systems to use JBL's patented Differential Drive technology with ferrite drivers featuring high power, wide bandwidth and low distortion. Versatile, scalable, easy-to-transport and set up, the PRX700 Series use JBL's tour tested technology throughout for a lifetime of reliable performance you can trust.
