DELTA 918 FS

18" High Performance Flying Subwoofer

Product at a Glance

The British Acoustics Delta 918 FS is a flying subwoofer designed to deliver powerful low-frequency performance in environments where floor space is at a premium. Ideal for live sound applications, the Delta 918 FS can be stacked or flown with the Delta 930 without the need for additional array frames, offering acoustic compatibility for seamless integration. This flexibility enables multiple configurations, addressing specific needs in a variety of setups.

Built with optimised brace positioning and minimised destructive nodal conditions, the Delta 918 FS benefits from advanced resonance mapping that results in a structurally robust housing. This design reduces unwanted cabinet coloration, leading to clearer sound output and improved overall performance, especially in demanding environments. As a front-loaded subwoofer, the Delta 918 FS provides deep, impactful low-end reproduction. Its rugged, perforated steel grille, combined with an acoustically transparent cloth backing, protects the driver while maintaining optimal audio quality.
Engineered for large-scale touring, the Delta 918 FS offers exceptional performance and flexibility.

CRAFTSMANSHIP

Painstakingly Perfect Production

Over the years, craftsmanship has been closely linked with small scale individualistic production. Back in 1972, we started the same way. As we grew in scale & size, it was difficult to build each speaker individually, but quality control was of utmost importance as so switching to a general assembly line was simply not an option. So we wrote up a code, one quite like enigma, to ensure quality control. We selected the right partners, got the right tools, and in cases where those weren't available, we invented them. We grew slower than most as our aim was to last longer than most.
