JBL SRX828SP - 2000W 2 x 18-inch Powered Portable Subwoofer in Black Finish

The JBL Professional SRX828SP is a high-performance, self-powered dual 18-inch subwoofer designed to deliver deep, extended low frequencies and high output for a wide range of applications. Whether used in small or medium-sized installations, touring setups, or as part of a larger SRX800 system, the SRX828SP excels in producing exceptional bass and low-frequency response. This powerful subwoofer is designed to integrate seamlessly with other SRX800 full-range systems and subwoofers, making it an integral component of a fully customizable, high-performance audio system.

The SRX828SP uses two 18-inch woofers with JBL's patented Differential Drive technology. This technology reduces weight while maximizing amplifier efficiency, ensuring the subwoofer delivers high power with minimal distortion. Equipped with 3-inch voice coils and dual ferrite drivers, the SRX828SP provides exceptionally low distortion and extended low-frequency output. This combination of features ensures that the subwoofer can handle extremely high SPL levels, producing up to 141 dB peak output, making it ideal for large-scale events and performances.

One of the standout features of the SRX828SP is its comprehensive user-configurable DSP (digital signal processing) suite. The subwoofer offers 20 parametric equalizers (PEQs), 2 seconds of delay, signal generators, input mixing, amplifier monitoring, and 50 recallable preset slots, including several JBL-engineered application presets. This level of customization ensures that the SRX828SP can be optimized for a variety of sound environments, from concert halls to outdoor festivals. Additionally, the system is compatible with V5 JBL Tunings, 96kHz FIR filters, and LevelMax Limiting, which provides compatibility with JBL's flagship Vertec and VTX touring systems. The SRX828SP can be controlled via Audio Architect or a standalone app for iOS and Android devices, allowing for easy system management and network control. Wired control is also available through an Ethercon connector, and wireless control is possible using a standard off-the-shelf wireless router.

The SRX828SP is built with durability in mind. The lightweight poplar plywood enclosure is made structurally sound with tongue-and-groove joints, and is coated with JBL's rugged DuraFlex finish for added protection against wear and tear, making it perfect for touring environments. The subwoofer's enclosure also features a powder-coated 14-gauge perforated steel grille with acoustically transparent black cloth backing for added durability while ensuring sound clarity. To ensure maximum versatility, the SRX828SP comes with 8 handles for easy transport, and it is compatible with the JBL WK-4S caster kit for added mobility on stage or in installations.
