JBL’s new SRX900 Series of powered line arrays and subwoofers offers affordable, scalable small and medium-format sound-reinforcement for rental companies, fixed installations and musicians.

The SRX900 Series offers a complete system solution, including speakers, subwoofers and accessories that support a variety of configurations and simplify storage, transport and rigging. The family includes dual 6.5-inch and dual 10-inch powered line array loudspeakers, and 18-inch and dual 18-inch powered subwoofers. Their scalability allows users to start with a small investment and expand as required – all SRX900 models work with other JBL touring PA systems.

Taking inspiration from JBL’s flagship VTX line, the SRX900 Series’ custom-designed and manufactured transducers, coupled with JBL horn and waveguide designs, claim to challenge the performance of more expensive three-way systems.

JBL SRX900 SeriesSRX900 woofers are based on JBL’s proprietary Differential Drive dual-voicecoil, dual-gap arrangement design, which claims better heat dissipation, lower power compression and wider dynamic range over conventional single-coil designs. Transducers feature neodymium magnet structures, and heat sinks are integrated into driver frames.

The SRX900’s 2432H-3 compression driver features a neodymium magnet structure, 3-inch titanium diaphragm and a 1.5-inch exit, offering extended sensitivity beyond 10kHz. SRX900 Series line arrays are based on JBL’s Radiation Boundary Integrator design, first introduced in the VTX Series. The patented RBI device mounts both the high- and low-frequency transducers on a single horn, improving horizontal dispersion while minimising cabinet size. A precision waveguide provides cabinet-to-cabinet summation for front-to-back coverage, and a large horn extends low-frequency control and reduces unwanted energy behind the array.

SRX900 models feature a DSP package that provides everything needed to optimise and tune systems, including 24-band parametric EQ, 2,000ms of delay and gain control. JBL’s proprietary Array Size Compensation (ASC) filter corrects for different array sizes, while the FIR-based Throw Distance Compensation (TDC) filter compensates air-imposed sound loss. An internal noise generator can be used to test the system without the need for a console.

The SRX900 Series’ LevelMax limiter suite, developed for Crown’s I-Tech HD professional touring amplifiers, uses excursion-control algorithms to protect transducers from mechanical damage. RMS limiting and long-term thermal protection keep transducer temperatures under control, ensuring reliable operation under any conditions.

The SRX900 Series supports Harman’s new HControl ethernet protocol, which brings advances in stability, reduces network traffic load and removes the need for complex IP addresses; users set a numerical value to each device for easy identification. Two switched network ports offer simplified networking for daisychaining. SRX900 products are equipped with Ethernet ports to facilitate monitoring and configuring the system over the network. Because SRX products use standard Ethernet protocols, customers can take advantage of inexpensive networking products such as Ethernet switches and Wi-Fi access points.

The SRX900 Series’ unified software suite lets users manage system design, control and deployment functions on Windows, macOS, and iOS. Use JBL LAC-3 simulation software for system design and the new, cross-platform JBL Performance application for system management; transfer rigging information via the Array Link iOS/Android companion app. A rear-panel LCD screen provides full on-speaker access to control features, making it easy for users to troubleshoot large systems or configure small systems onscreen.

The series’ custom class-D amplifiers are designed from the ground up for optimal performance alongside matched SRX900 transducers; amplifiers are passively cooled, with no open holes that could allow water or dust to enter the electronics. A universal switch mode power supply works on any voltage between 100V and 250V, and a low power mode kicks in when no audio is detected, saving energy. Up to eight SRX906 speakers and four SRX910 speakers can be connected to the same power circuit (depending on region), minimising cable complexities and cost.

SRX900 Series systems are designed for both portable and installed applications and can be deployed in a variety of configurations, from pole-mounted to groundstacked to flown arrays of up to 16 cabinets. A three-point rigging system, adapted from VTX technologies, makes suspending systems safe and easy, regardless of system size or user experience level. Splay angles are set on the ground, and cabinets lock into place as the system is lifted. The rear rigging spine serves as an additional heat sink for cooling. Available accessories include array frames, base plates, pole-mount and truss-clamp adapters, cases, carts and covers.

SRX900 Series line array loudspeakers are housed in reinforced composite enclosures while subwoofers feature 18mm plywood enclosures. FEA-optimised cabinets offer excellent size-to-weight ratio and are acoustically optimised for performance: Four large, double-flared low-frequency ports allow airflow even when driving the system to the limit; flares control air velocity at the ports’ exit, eliminating interference noise at the grille, and CAD-optimised stiffeners minimise flex. The cabinets are designed for a clean look, with enclosed side panels and integrated handles.
