Description
Audio professionals in need of a subwoofer that's designed to complement the SRX900 Series full-range sound reinforcement systems will be impressed with the JBL SRX918S, a single 18" powered subwoofer well suited for rental companies, touring artists, DJs, and installations. The integrated DSP and amplification offer a true plug-and-play experience while providing consistency and optimum performance anywhere in the world. The 18" Differential Drive woofer is powered by the built-in Class-D amplifier and provide a frequency response of 35 to 90 Hz at 134 peak SPL. The SRX918S incorporates a large low-frequency port design that improves airflow and reduces audible turbulence, even at high output levels. A full-featured software package provides users control of the system on various platforms including Windows, Mac, and iOS for iPad. Performance The 2279-1 18-inch woofer delivers transparent, linear bass response down to 35 Hz. This driver uses dual 3" voice coils and leverages JBL's patented Differential Drive technology to deliver maximum sensitivity and power handling in a light, compact design. Compatibility SRX900 Series subwoofers are acoustically compatible with all SRX900 full-range speakers and support 60 and 80 Hz operating modes. SRX900 line arrays can be ground stacked with SRX900 subwoofers using the optional base plate accessories. Controlled Coverage SRX900 subwoofers can be used in omnidirectional or cardioid configurations simply by selecting the appropriate speaker preset and cabinet orientation. The preset can be accessed directly from the rear panel LCD or via software. Powered Solution The fully integrated built-in amplifier and DSP are based on proven JBL technologies and explicitly packaged to fit the needs of the SRX900 Series. The DSP includes everything needed to optimize a system, including 24 user-adjustable filters, 2000ms of delay, and advanced features like array size compensation and FIR-based throw-distance correction filters. Versatile and Scalable The SRX900 Series offers a complete system solution, including speakers, subwoofers, accessories, and software that support a variety of configurations and simplify storage, transport, and rigging. Because systems are scalable, it's easy to start with a small system and add components over time. All SRX900 products have been designed to work seamlessly together with other JBL tour sound products, with common voicing targets and phase characteristics that ensure systems combine coherently.

Support answered my question before I ordered, which made the decision easy. No regrets so far.
Sounds fantastic on stage
Marc L. ·
Does everything I need for mobile gigs. Compact enough to carry alone and tough enough for weekly transport.
Great for small venues
Renée D. ·

Build quality feels well above the price. Controls are laid out sensibly and nothing rattles or flexes.
Solid build, great value
Jasmine T. ·
Used it for three shows already and it has been rock solid. Setup took minutes and the sound is clean at high volume.
