Description
JBL SRX928S Dual 18-inch Active Subwoofer
The JBL SRX928S Dual 18-inch Active Subwoofer is engineered to complement SRX900 full-range sound reinforcement systems, delivering high-impact low-frequency performance for professional touring, rental, and installation applications. Designed for maximum output and reliability, this active subwoofer integrates advanced transducer technology, onboard DSP, and built-in amplification into a powerful, plug-and-play solution.
The system houses two JBL 2279-1 18-inch woofers featuring Differential Drive technology. This dual voice coil, dual gap design improves heat dissipation, reduces power compression, and expands dynamic range compared to conventional single-coil designs. The result is consistent, high-output bass performance with enhanced clarity and reliability, even under demanding operating conditions.
With a frequency range of 31 Hz to 100 Hz (-10 dB) and a maximum peak SPL of 140 dB, the SRX928S delivers deep, controlled bass suitable for large-scale sound reinforcement environments. Built-in DSP and amplification provide optimized system performance worldwide, ensuring consistent tonal balance and system protection.
The enclosure incorporates a large central low-frequency port design that improves airflow efficiency and minimizes audible turbulence at high output levels. System configuration and monitoring are supported through a full-featured software package compatible with Windows, macOS, and iPad OS platforms, offering flexible control for professional deployments. The JBL SRX928S provides scalable, high-output bass reinforcement for demanding SRX900 applications.
