Aura Sub 312S
12" Compact Installation Subwoofer
Product at a Glance
The British Acoustics Aura Sub 312S is a 12" compact installation subwoofer engineered for deep, defined bass in professional audio environments. With a 132 dB peak output and response down to 35 Hz, it delivers strong low-end reinforcement for small to mid-sized venues. An aluminium demodulating ring reduces distortion, while optimised airflow minimises compression. Housed in marine birchply with scratch-resistant polyurea coating, it offers lasting durability. Integrated handles, M10 flying inserts, and round feet allow flexible placement. Finished in the brand’s signature umber brown with RAL customisation options, the Aura Sub 312S merges clarity, strength, and installation-ready design.
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.
