OctaLine 12 LA
12" Self-Powered, Constant Curvate Array
Product at a Glance
The OctaLine 82H LA is a 12" powered constant curvature array speaker, designed to deliver impeccable sound clarity and consistent coverage for professional audio applications. With its precise horizontal dispersion and array-dependent vertical pattern, it ensures balanced and immersive audio across a wide frequency range. Built for versatility, it excels in medium to large venue setups, offering seamless integration with subwoofers like the OctaLine 88S and OctaLine 84FS for a complete audio experience. The 3000W Class-H amplifier and built-in 24-bit DSP ensure superior voicing, system protection, and enhanced efficiency for demanding environments.
Engineered for durability and adaptability, the OctaLine 82H LA features a marine-grade birch plywood enclosure, scratch-resistant polyurea paint, and a robust rigging system with quick-lock pins for easy deployment. Its constant curvature design allows up to six units to be flown or ground-stacked without the need for an array frame. Aesthetic elements like non-reflective matte black grills and British Acoustics' signature brown tone ensure it complements any professional setting. Whether flown or stacked, the OctaLine 82H LA delivers unparalleled performance, making it an essential tool for live events, touring, and installations.
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.
