Product at a Glance
The British Acoustics Alpha Club Sub S is a dual 18" horn-loaded subwoofer built for extreme low-frequency output in dance venues, festivals, and touring systems. Delivering 140 dB continuous and 146 dB peak SPL, it provides seismic bass reinforcement with 80–120 Hz crossover and cardioid presets for directional control. Its marine-grade birchply cabinet with polyurea coating withstands harsh use, while integrated handles, M10 inserts, and locking feet support flexible stacking or flying. A custom Triple Venting System ensures thermal stability, and perforated steel grilles offer protection. The Alpha Club Sub S delivers unmatched power, precision, and durability for high-demand applications.
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.
