JBL announces the new PRX900 series of powered loudspeakers and subwoofers, professional portable PA speakers with newly designed acoustics, comprehensive DSP, and complete BLE control via the JBL Pro Connect ecosystem. The line, which includes three powered two-way loudspeakers and two powered subwoofers, has been built from the ground up to leverage JBL’s acoustic innovations. “Next-generation driver systems—powered by ultra-efficient 2,000-watt (peak) Class D amplifiers—deliver clarity and definition at maximum volume, with improved dispersion and smooth low-frequency extension,” according to the announcement. The PRX900 Series is designed to be portable or installed for house of worship, DJs and bands, music venues, rental houses, corporate A/V providers.
New Acoustic Design
Patented JBL 2408H-2 1.5” compression drivers with poly-annular diaphragms and neodymium magnets are designed to bring clear, detailed high-frequency response even at maximum volume. 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. Next-generation woofers with ferrite magnets are designed for smooth, natural bass response, and an FEA flared port design reduces air noise and distortion. Subwoofers feature proprietary voice coils for improved low-frequency response.
DSP and Control
The PRX900 Series features 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.
The JBL 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 the ability to change speaker names and flash all unit LEDs for ease of speaker identification in a full ecosystem. Users may access full DSP functions anywhere from the app, including app-only features like speaker snapshots and groupings.
Versatility and Scalability
PRX900 Series loudspeakers and subwoofers can be combined in a range of configurations to meet the needs of both mobile scenarios and fixed installs. PRX900 speakers feature dual 36mm pole sockets and six M10 suspension points; subwoofers feature M20 pole cups. A built-in G-Sensor gyrosensor automatically optimizes system tuning depending on monitor or mains placement.
Portability
PRX900 components are housed in cabinets designed for both acoustic performance and durability. Loudspeaker cabinets are constructed from a polypropylene/talcum blend for rigidity, with a computer-modeled internal ribbing design that improves strength and acoustic performance. Subwoofer enclosures are built from 18mm birch, with bracing that smooths out low-frequency response; cabinets have Duraflex coatings for durability.
All JBL products, including the new PRX900 Series loudspeakers and subwoofers undergo a 100-hour stress test of all components to ensure systems perform well in real-world scenarios. Each speaker is backed with a seven-year warranty.
Power
Driven by efficient 2,000W (peak) Class D power amps, the PRX900 Series is designed for acoustic clarity and definition with minimal power compression, even at maximum volume. It features a bridged woofer amp to keep current spikes out of the ground and lower crosstalk harmonics to the compression driver, and the power factor correction (PFC) power supply stabilizes voltage load sent to the amplifier. High-linearity inductors are included for power efficiency and low total harmonic distortion, and low-noise, as well as low-distortion input gain staging to optimize range and headroom for a diverse gain requirements. DAC and ADC provides near-lossless audio conversion. Producing up to 134 dB output down to 30 Hz, systems are designed to support large performance spaces with high power and performance needs. And with a full-bandwidth CMRR (Common Mode Rejection Ratio) greater than 55 dB and THD (total harmonic distortion) rating of 32 db.
Accessories
PRX900 system has essential accessories available including universal yoke mount, transport speaker bags and dependable high-quality mounting poles and tripod stands for quicker, more reliable setup. JBL offers durable speaker bags by Gator, and a variety of gas-assist and manual-adjust speaker stands built to match the PRX900 system.
