Alpha Club One
2 X 11.25", 3-Way Horn Loaded Club System
Product at a Glance
The Alpha Club One is a powerful and intelligently engineered 3-way horn-loaded loudspeaker system designed for high-performance club installations. Featuring two 11.25" Delta Drive low-frequency drivers with copper voice coils and Fortex™ weather-resistant cones, it delivers 500W AES of ultra-tight bass per driver, ensuring commanding low-end impact across the dancefloor. The system integrates a 1.4" MF compression driver and dual 1.25" HF compression tweeters, offering exceptional midrange clarity and sparkling highs.
The passive crossover network operates at 630 Hz and 6.3 kHz, optimally aligning the LF, MF, and HF components for seamless audio reproduction. With selectable dispersion patterns (70° × 40° or 90° × 50°), the Alpha Club One adapts effortlessly to different venue geometries. Built with a marine birchply enclosure and protected by a stainless steel grille, the cabinet is as rugged as it is refined, finished in British Acoustics’ signature umber brown tone with blue decal accents.
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.
