Description
The JBL PRX915XLF is a 15-inch powered subwoofer from the PRX900 Series, built for professional portable PA – DJ shows, bands and events – as well as fixed installs. It pairs with JBL's PRX900 full-range speakers and is set up from its own colour screen or a phone app.
Highlights
- 915SG 15″ ferrite-magnet woofer with a 3″ voice coil, in an 18 mm birch plywood cabinet with optimised bracing.
- Class D amplifier rated 2,000 W peak / 1,000 W RMS; 131 dB maximum SPL at 1 m.
- Extends to 36 Hz (−10 dB); crossover selectable at 80, 100 or 120 Hz.
- DSP with 6-band parametric EQ, limiter, speaker delay for time alignment and presets for pairing with full-range tops.
- JBL Pro Connect app controls up to 10 speakers over Bluetooth LE, including EON ONE MK2, PRX ONE and EON700.
- Fanless cooling, latency under 1 ms and a flared port that reduces air noise.
In your setup
Feed the mixer's main outputs into the two combo inputs and send the signal on to the tops from the two XLR thru outputs. The M20 pole cup on top takes a speaker pole for a PRX900 full-range cabinet. A polarity switch and the onboard delay help line up sub and tops. The cabinet weighs 28.6 kg; JBL offers an optional caster board, the PRX915XLF-CASTERBRD, for moving it.
