SRX800 Passive: JBL's Touring and Event DNA in a Passive Subwoofer Version
The JBL SRX800 Passive series was designed to offer, in a transportable format, a level of sound quality, power, and reliability tailored for intensive use. The SRX818S fits this logic: an 18-inch passive subwoofer built around JBL components, with a field-oriented construction to meet the demands of mobile sound reinforcement and challenging configurations.
A Subwoofer for Providers, DJs, and Live Stages Seeking Controlled Bass
The JBL SRX818S targets users who prioritize external amplification and a system approach: providers, sound engineers, venues, bands, and DJs looking for a subwoofer capable of delivering a solid low end without sacrificing precision. It naturally integrates under front speakers to add impact on kick drums, synths, bass guitars, and electronic music, while maintaining a usable response for vocals and amplified instruments.
Design, Components, and Performance: The Efficiency of a Road-Ready 18-Inch Sub
JBL 2279H Driver: Efficiency and Power Handling
At the heart of the SRX818S, the JBL 2279H (18 inches) is sized to provide bass that is both energetic and controlled. With a sensitivity of 96 dB (1W/1m) and a maximum SPL rated at 135 dB, the subwoofer is designed to perform when levels rise, whether at front of house or as sub reinforcement at events.
System Management: Optimized Presets and Harman Professional Ecosystem
To get the best from the speaker in a playback context, the SRX800 series relies on an integration logic: optimized presets available in Crown amplifiers and dbx processors. This approach facilitates achieving a coherent sound (filtering, equalization, protection) and fits into a system controllable via Audi-Architect, convenient for installed setups or multi-speaker systems.
Build and Transport: 18 mm Plywood and Duraflex(TM) Finish
The 18 mm plywood enclosure and Duraflex(TM) finish meet the demands of handling, loading, and regular use. The format remains suitable for events where a good balance between impact, depth, and portability is sought, with a controlled weight for its category.
