Dual 18-inch Powered Subwoofer
- Open Box -
Description
The SRX928S is a dual 18-inch active subwoofer designed to complement SRX900 full-range sound reinforcement systems. The subwoofer houses two JBL 2279-1 18-inch woofers, featuring Differential Drive® – JBL’s dual voice coil, dual gap technology – to deliver better heat dissipation, lower power compression, and wider dynamic range than conventional single-coil designs. Built-in DSP and amplification offer a plug and play experience, while providing consistency and optimum performance anywhere in the world. The SRX928S incorporates a large central low frequency port design that improves airflow and reduces audible turbulence, even at high output levels. A new, full-featured software package gives users control of the system on various platforms, including Windows, macOS, and iPad OS.
