JBL PRX918XLF 18-inch powered subwoofer

The PRX918XLF is the larger PRX900 subwoofer. An 918SG 18-inch ferrite woofer in an 18 mm braced birch cabinet with an FEA-designed flared port runs on 2,000 W peak of Class D power, reaching 30 Hz at -10 dB for a maximum of 134 dB. The crossover point is selectable at 80, 100 or 120 Hz.

The DSP suite is reached from an onboard colour LCD or from the JBL Pro Connect app over Bluetooth: 12-band parametric EQ, dbx DriveRack Automatic Feedback Suppression, a soft system limiter with a Soundcraft Overeasy option, and 180 ms of speaker delay in 100-microsecond steps. One app session controls up to ten cabinets and lines the PRX900 up with EON700, PRX ONE and EON ONE MK2 systems. Two combo inputs and two XLR pass-throughs handle daisy-chaining, and the top surface carries the pole mount for a PRX900 top.
