HARMAN Professional Solutions has introduced the JBL PRX900 Series of loudspeakers and subwoofers, which feature ‘advanced acoustics, comprehensive DSP, unrivalled power performance’ says the maker, with additional BLE control via the JBL Pro Connect app.

The line, which includes three powered two-way loudspeakers and two powered subwoofers, is built from the ground up to leverage JBL’s acoustic innovations. All-new proprietary driver systems – powered by ultra-efficient Class D amplifiers – deliver clarity and definition at maximum volume, with improved dispersion and beam width and low-frequency extension.

The PRX900 Series’ DSP package, accessible via onboard LCDs and the JBL Pro Connect app, includes 12-band parametric EQ for system tuning and nuanced tonal control, and integrated dbx Drive Rack technology, featuring live and fixed automatic feedback suppression, soft system limiter with Soundcraft Overeasy option and speaker delay settings and presets.

The JBL Pro Connect app can be used to control up to 10 speakers, integrate with JBL EON ONE MK2, PRX ONE, and EON700 systems, and access app-only functions including speaker snapshots and grouping.

The PRX900 Series is designed to withstand the rigors of the road. Rigid composite loudspeaker cabinets feature computer-modelled ribbing for optimal acoustic performance and durability, while subwoofers are housed in 18mm birch cabinets with bracing for smooth, accurate low-frequency response.

“For years, our PRX800 Series loudspeakers have been first-call systems for bands, DJs, installers and houses of worship in large part thanks to their acoustic profile, their low end extension, and their volume,” says Brandon Knudsen, HARMAN Professional Product Manager, Portable PA Loudspeakers. “With the PRX900 Series, we’re taking things to the next level with next-gen acoustic innovations and an even brawnier power package to deliver clean, clear sound at any volume. Systems take advantage of the latest BLE technology and the JBL Pro Connect app ecosystem, for unrivalled control.”

The PRX900 Series is a versatile solution for DJs and bands, music venues, rental houses, corporate A/V providers, or anyone who seeks durable professional systems that deliver sound in any portable or installed scenario. Key innovations include:

All-new acoustic designs

From cones to cabinets, the PRX900 Series is designed for advanced acoustic performance. Patented JBL 2408H-2 1.5in compression drivers with poly-annular diaphragms and neodymium magnets provide clear, high-frequency response; new horns with updated JBL Image Control Waveguides have been designed to deliver consistent beamwidth and frequency dispersion. Next-generation woofers with ferrite magnets deliver a smooth bass response, and an FEA flared port design reduces air noise and distortion.

Power performance

Driven by highly efficient Class D power amps, the PRX900 Series 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 tweeter. High-linearity inductors deliver superior power efficiency and low total harmonic distortion, and low-noise, low-distortion input gain staging optimises range and headroom for gain requirements. DAC and ADC provides near-lossless audio conversion. Producing up to 134dB output down to 30Hz, systems support large performance spaces with power and performance requirements. And with a full-bandwidth CMRR (Common Mode Rejection Ratio) greater than 55dB and THD (total harmonic distortion) rating of <32 dB, noise is virtually non-existent, according to the maker.


The PRX900 Series is loaded with comprehensive DSP, all accessible via the JBL Pro Connect app or onboard full-colour LCD. Processing includes 12-band parametric EQ, plus optimised presets and snapshots. Onboard dbx DriveRack technology features live and fixed Automatic Feedback Suppression, hard and soft system limiters and 180ms of speaker delay in 100-microsecond intervals for full time-aligned systems.

Versatile and scalable

Combine PRX900 Series loudspeakers and subwoofers in a range of configurations to meet the requirements of both mobile scenarios and fixed installs. Speakers feature dual 36mm pole sockets and six M10 suspension points; subwoofers feature M20 pole cups. Full-range speakers feature a built-in gyrosensor that optimises system tuning depending on monitor or mains placement.

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. Access full DSP functions right from the app, including app-only features like speaker snapshots and speaker groupings.

Rugged and road-worthy

PRX900 components are housed in strong, lightweight cabinets that maximise both acoustic performance and durability. Loudspeaker cabinets are constructed from a polypropylene/talc blend that’s optimised for rigidity, with computer-modelled internal ribbing designed for maximum structural integrity and minimal cabinet noise. Subwoofer enclosures feature optimised bracing that smooths out low-frequency response.
