Alpha Club Sub S
Dual 18" Horn Loaded High Power SUBWOOFER SYSTEM


Product at a Glance
The Alpha Club Sub S is a purpose-built, high-output subwoofer engineered to deliver immense low-frequency energy for high-capacity dance venues, outdoor festivals, and touring-grade sound systems. Its dual 18" ultra-high excursion drivers are precision-loaded into a horn-loaded cabinet, producing a thunderous 140 dB continuous SPL and peaking at a seismic 146 dB—making it the go-to choice when extreme bass reinforcement is non-negotiable. Designed for both horizontal and vertical deployment, the Sub S adapts easily to stack configurations in complex system setups.
The cabinet is constructed from marine-grade birchply and coated with granular scratch-resistant polyurea for unmatched durability in harsh touring conditions. Integrated handles, M10 flying inserts, and stackable locking feet ensure fast and secure rigging whether used ground-stacked or flown. With an 80–120 Hz active crossover, omnidirectional dispersion, and cardioid presets for directional bass control, the Alpha Club Sub S offers both brute force and acoustic precision. A custom-engineered Triple Venting System keeps internal temperatures stable during peak performance, maintaining driver reliability and sonic consistency. Finished with perforated black pressed steel grilles, this subwoofer is as tough as it sounds—ready to shake venues without breaking a sweat.
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.
