JBL SRX928S
Dual 18-inch Powered Subwoofer
The SRX900 Series embodies the advanced performance principles that drive JBL’s development of audio products that make a real difference in the world of professional audio. This next-generation family of powered line arrays and subwoofers addresses the growing need for scalable small and medium-format professional sound-reinforcement solutions for rental companies, fixed installations and musicians seeking the ultimate combination of performance and portability.
The SRX928S is a dual 18-inch active subwoofer designed to complement SRX900 full-range sound reinforcement systems. The sub¬woofer 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. Learn more about JBL Performance here.

Footnotes:
1: Based on speaker preset selection and cabinet orientation/configuration.
2: Peak, unweighted SPL, measured under half-space conditions at 1 meter using broadband pink noise with a 12 dB crest factor and specified preset.
3: Bench power: ≥1 sec, 1 kHz, 120 VAC, no DSP, all channels driven.
4: Burst power: ≥20 ms, 1 kHz, 120 VAC, no DSP, all channels driven.
5: System test using IEC shaped pink noise with 9 dB crest factor. System at maximum output without clipping or limiting. Ambient temperature: 20° C. Duration: 5 sec. 6: Two-tone, all channels driven, IMD test at maximum power and a duration of 200 ms.
7: Measured RMS inrush current for a 50 ms window.
8: With use of SRX900 RC1 rain cover (JBL-P3239MX ) and front face at 0 degrees or greater down angle to allow the cabinet to drain water. Components fully weather rated for indoor or covered outdoor conditions where humidity is nominally under 50% and not local to bodies of corrosive materials.
