DESCRIPTION
The JBL PRX918XLF is a self-powered 18-inch subwoofer built to extend the low-frequency reach of portable and semi-permanent PA systems. It is aimed at engineers, integrators and working musicians who need substantial output from a single box, with the DSP tools to time-align and tune it properly on site.
A 918SG ferrite-magnet woofer is loaded into an 18mm birch cabinet with optimised internal bracing, while an FEA-modelled flared port reduces air noise and port compression at high drive levels. Class D amplification keeps weight down and runs fanless, so the cabinet stays silent between programme material. Two XLR combo inputs and two pass-through outputs simplify daisy-chaining, and an M20 pole cup carries a full-range top. Setup is handled from the colour LCD screen or remotely through the JBL Pro Connect app.
- 2,000 W peak / 1,000 W RMS Class D amplification
- Maximum SPL of 134 dB
- Frequency response 30 Hz\-10 dB) at 2pi
- DriveRack DSP with 180 ms of delay in 100-microsecond steps for time-aligned systems
- Bluetooth control of up to 10 speakers via JBL Pro Connect, with system latency under 1 ms
Well suited to live events, touring rigs, houses of worship, corporate AV, hospitality venues and installation work where portable low-end extension is required.
