The SRX918S is a single 18-inch active subwoofer designed to complement SRX900 Series full-range sound reinforcement systems.
The subwoofer houses a JBL 2279-1 18-inch woofer 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 SRX918S
incorporates a large low frequency port design that improves airflow and reduces audible turbulence, even at high output levels.
full-featured software package gives users control of the system on various platforms, including Windows, macOS, and iPad OS.
The 2279-1 18-inch woofer delivers transparent, linear bass response down to 35 Hz. This driver uses dual three-inch voice coils
and leverages JBL’s patented Differential Drive technology to deliver
maximum sensitivity and power handling in a light, compact design.
SRX900 Series subwoofers are acoustically compatible with all
SRX900 full-range speakers and support 60 Hz and 80 Hz operating modes. SRX900 line arrays can be ground stacked with SRX900
subwoofers using the optional base plate accessories.
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.
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, 2,000 ms 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.
