HARMAN Professional Solutions has announced the introduction of the JBL Professional PRX900 Series that includes three powered two-way loudspeakers and two powered subwoofers with all-new proprietary driver systems powered by Class D amplifiers.
The PRX900 Series’ DSP package, accessible via onboard LCDs and the JBL Pro Connect app, includes 12-band parametric EQ for system tuning and more nuanced tonal control, and integrated dbx Drive Rack technology with live and fixed Automatic Feedback Suppression, soft system limiter with Soundcraft Overeasy option, and delay settings and presets.
Users can employ the JBL Pro Connect app to control up to 10 loudspeakers, integrate with JBL EON ONE MK2, PRX ONE, and EON700 systems, and access app-only functions including loudspeaker snapshots and grouping.
The rigid composite cabinets incorporate computer-modeled ribbing for more optimal acoustic performance and durability, while subwoofers are housed in 18 mm birch cabinets with optimized bracing. The PRX900 Series is subjected to the company’s test and validation protocols and is backed by a seven-year warranty.
“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 unrivaled control.”
Onboard the loudspeakers are patented JBL 2408H-2 1.5-inch compression drivers with poly-annular diaphragms and neodymium magnets that are designed to provide clear high-frequency response as well as new horns with updated JBL Image Control Waveguides designed to deliver consistent beamwidth and frequency dispersion. The woofers with ferrite magnets work with an FEA flared port design to help reduce air noise and distortion.
A bridged woofer amp is designed to keep current spikes out of the ground and lower crosstalk harmonics to the tweeter. High-linearity inductors are designed to enhance power efficiency and lower total harmonic distortion, and the input gain staging is designed to optimize range and headroom for diverse gain requirements.
The DAC and ADC are stated to provide near-lossless audio conversion. Maximum SPL is stated as 134 dB down to 30 Hz. Full-bandwidth CMRR (Common Mode Rejection Ratio) is specified as greater than 55 dB and THD (total harmonic distortion) rating is <32 dB.
Cabinets also include dual 36 mm pole sockets and six M10 suspension points; subwoofers offer M20 pole cups. Full-range models also include a built-in gyrosensor that is designed to automatically help optimize system tuning depending on monitor or mains placement.
