JBL PRX915XLF 15-inch powered subwoofer

The PRX915XLF is the compact subwoofer for a PRX900 rig: a 915SG 15-inch ferrite woofer on 2,000 W peak of Class D power, reaching 36 Hz at -10 dB and making 131 dB at one metre. The crossover is switchable at 80, 100 or 120 Hz, so it matches whichever PRX900 top sits on the pole above it.

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-through outputs feed the next cabinet, and the pole mount is on the top surface.
