JBL PRX908 8" Two-Way Powered PA Loudspeaker

The JBL PRX908, part of the PRX900 Series of powered loudspeakers and subwoofers, takes professional portable PA performance to a new level with advanced acoustics, comprehensive DSP, unrivaled power performance and durability and complete BLE control via the JBL Pro Connect app. 

This powered two-way 8-inch loudspeaker is built entirely from the ground up to leverage JBL’s most advanced acoustic innovations. A next-generation driver system—powered by an ultra-efficient Class D amplifier—delivers clarity and definition at maximum volume, with improved dispersion and smooth low-frequency extension.

PRX908’s class-leading DSP package, accessible via an onboard color LCD or the JBL Pro Connect app, features 12-band parametric EQ for system tuning and nuanced tonal control; integrated dbx DriveRack technology includes live and fixed Automatic Feedback Suppression, soft system limiter with Soundcraft Overeasy option and speaker delay settings and presets.

The JBL Pro Connect app provides complete hardware and DSP control of up to 10 speakers; integrate PRX900 Series models with JBL EON ONE MK2, PRX ONE and EON700 systems and access app-exclusive functions including speaker snapshots and grouping.

The PRX908 is designed to withstand the rigors of the road. Its composite cabinet features a computer-modeled internal ribbing design that increases overall cabinet rigidity, which improves acoustic performance and durability. Like with every JBL product, everything is reinforced by industry-leading test and validation protocols and backed by a seven-year warranty.

The PRX900 Series is a versatile solution for professional DJs and bands, music venues, rental houses, corporate A/V providers, or anyone who needs durable professional systems that deliver powerful, room-filling sound in any portable or installed scenario.

FEATURES:

All-New Acoustic Designs

From cone to cabinet, the PRX908 has been built from the ground up to leverage the latest JBL acoustic innovations. A patented JBL 2408H-2 1.5” compression driver with poly-annular diaphragm and neodymium magnet provides clear, detailed high-frequency response even at maximum volume. High-quality NTC thermistors protect transducers by reducing power sent to transducers when approaching thermal limit. Innovative new horns with updated JBL Image Control Waveguides provide optimum beamwidth and directivity. A next-generation woofer with ferrite magnet delivers smooth, natural bass and mids.

Power that Performs for You

PRX900 systems effortlessly support large performance spaces with high power and performance needs. Driven by a highly efficient 2,000W (peak) Class D power amp, PRX908 provides acoustic clarity and definition with minimal power compression, even at maximum volume. A bridged woofer amp keeps current spikes out of the ground and lowers crosstalk harmonics to the compression driver, and a power factor correction (PFC) power supply stabilizes voltage load sent to the amplifier. High-quality, high-linearity inductors deliver high power efficiency and low total harmonic distortion, and low-noise, low-distortion input gain staging optimizes range and headroom for a diverse gain requirements. A high-quality DAC and ADC provide near-lossless audio conversion. And with a full-bandwidth CMRR (Common Mode Rejection Ratio) greater than 55 dB and THD (total harmonic distortion) rating of <32 dB, system noise is virtually nonexistent.

Dial In Your Sound With Class-Leading DSP

PRX908 is fully loaded with comprehensive DSP, all accessible via the JBL Pro Connect app and onboard full-color LCD. Processing includes 12-band parametric EQ and optimized system presets. Onboard dbx DriveRack technology features live and fixed Automatic Feedback Suppression, soft system limiters and 180ms of speaker delay in 100-microsecond intervals for precise time-aligned systems.

Versatile and Scalable

Combine PRX900 Series loudspeakers and subwoofers in a range of configurations to meet the needs of both mobile scenarios and fixed installs. PRX908 features dual 36mm pole sockets and six M10 suspension points. A built-in gyrosensor automatically optimizes tuning depending on monitor or mains placement.

Part of the Pro Connect Ecosystem

JBL’s Pro Connect app offers BLE functionality for system control of up to 10 speakers and line integration with JBL EON ONE MK2, PRX ONE, and EON700 loudspeakers. The app provides full access to to the PRX900 Series' DSP package, and users can easily mute channels and speakers with the touch of a button and can change speaker names and flash all unit LEDs for ease of speaker identification. App-exclusive features include speaker snapshots and groupings.

Rugged and Road-Worthy

PRX908 components are housed in a strong, lightweight enclosure that maximizes both acoustic performance and durability. Its cabinet is constructed from a polypropylene/talcum blend that’s optimized for rigidity, with a computer-modeled internal ribbing design for maximum structural integrity and minimum cabinet noise.

In It for the Long Haul

Like every JBL product, the PRX908 undergoes an industry-leading 100-hour stress test of all components to ensure systems perform beyond expectations in real-world scenarios. It’s so reliable that it’s backed with an unprecedented seven-year warrant.
