Alpha Club Twelve S
Dual 12" Compact Subwoofer - Twelve S
Product at a Glance
The Alpha Club Twelve S is a high-powered, compact subwoofer engineered for maximum low-end delivery in high-energy environments. Equipped with dual 12” low-frequency Delta transducers and rated at 1000W AES (4000W peak), it delivers extended bass response from 45 Hz to 100 Hz, with a peak SPL of 136 dB. Featuring omni-directional dispersion, cardioid presets, and an 8Ω impedance, it integrates seamlessly into large-scale systems and offers flexible deployment options. The active crossover (80–120 Hz) and SpeakOn input/thru facilitate streamlined connectivity for professional setups. Built with a marine birchply cabinet coated in granular, scratch-resistant polyurea paint, the Alpha Club Twelve S combines durability with power. Its design includes sloped input plates for improved cable management, perforated stainless steel grills backed by acoustic foam for protection, and M10 flying inserts for secure rigging. Finished in British Acoustics’ signature umber brown tone with optional blue grill decals, it is visually distinctive. IP42-rated components provide reliability for demanding indoor or outdoor use. Whether stacked horizontally or flown vertically, the Alpha Club Twelve S delivers clarity, depth, and impact, making it ideal for clubs and high-energy events.
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.
