JBL SRX918S 18in Powered Subwoofer

About: JBL SRX918S 18in Powered Subwoofer

The SRX918S is a single 18-inch powered subwoofer designed to complement SRX900 Series full-range sound reinforcement systems. The subwoofer houses a JBL 2279G-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. A full-featured software package gives users control of the system on various platforms, including Windows, macOS, and iPad OS.

• High-performance, high-density system solution in a truck-pack friendly format

• Built-in, passively cooled Class D amplification with a universal power supply
• Dual Ethernet ports with Neutrik etherCON connectors
• Supports HARMAN HControl Ethernet
• User-controllable DSP
• LevelMax limiting uses sophisticated excursion-control algorithms to protect transducers
• Rear-panel LCD provides complete access to control features
• Reinforced 18mm plywood enclosures

PERFORMANCE 

The 2279G-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. 

COMPATIBILITY 

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. 

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, 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.
