OctaLine 12 LA
12" Self-Powered, Constant Curvate Array
Product at a Glance
The British Acoustics OctaLine 12 LA is a 12" powered constant curvature array speaker engineered for consistent coverage and exceptional clarity in professional audio setups. With precise horizontal dispersion and array-based vertical pattern, it delivers balanced sound across venues. A 3000W Class-H amplifier and 24-bit DSP ensure efficient performance and protection. Housed in marine-grade birch plywood with polyurea coating, it features quick-lock rigging for easy deployment. Up to six units can be flown or stacked without an array frame. Finished with matte black grills and a signature brown tone, the OctaLine 12 LA excels in touring, installs, and live 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.
