Aura Sub 312 S
12" COMPACT INSTALLATION SUBWOOFER
Product at a Glance
The Aura Sub 312S is a 12" compact installation subwoofer designed to deliver deep, impactful bass with precision. Offering a peak output of 132 dB and a frequency range extending down to 35 Hz, it provides powerful low-end reinforcement ideal for a variety of professional audio applications, including small to medium-sized venues and installations. Its aluminum demodulating ring reduces distortion, while optimized airflow minimizes power compression, ensuring consistent and reliable performance. Built from durable marine-grade birch plywood with a scratch-resistant polyurea coating, the Aura Sub 312S withstands demanding environments. Integrated handles, round bottom feet for stable stacking, and M10 flying inserts allow versatile deployment—whether horizontal, vertical, or stacked. Featuring British Acoustics’ signature umber brown finish and customizable RAL color options, it blends functionality, durability, and style for superior audio solutions.
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.
