DELTA 925 FS

Dual 15" Flying Subwoofer

Product at a Glance

The British Acoustics Delta 925 FS is a flying subwoofer designed to deliver powerful, high-output low-frequency performance in environments where floor space is at a premium. Ideal for live sound applications, the Delta 925 FS can be stacked or flown with the Delta 920 LA and Delta 915 LA, offering acoustic compatibility for seamless integration into a wide range of setups. Featuring a horn-loaded design with dual 15" drivers, the Delta 925 FS provides exceptional bass response with enhanced efficiency and minimal distortion. This design ensures that it delivers deeper, cleaner low-end performance, perfectly complementing the Delta 920 LA and Delta 915 LA in terms of both output and frequency response. With a wider frequency range, it ensures smooth integration with the mid-high frequency line arrays.

Built for high SPL, the Delta 925 FS matches the output capabilities of the Delta 915 LA, providing powerful, consistent low-end coverage for large venues or touring setups. Its rugged, perforated steel grille, combined with an acoustically transparent cloth backing, offers reliable protection for the drivers while preserving optimal sound quality. Designed for large-scale touring and professional sound reinforcement, the Delta 925 FS is compact, versatile, and engineered to deliver impactful low-end performance, making it the perfect solution for space-constrained venues or large, high-output sound systems.

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.
