Sleek aesthetics, non-reflective matte black grills, and British Acoustics' signature umber brown tone ensure it blends seamlessly into any professional audio system. Whether used standalone or as part of a larger rig, the OctaLine 18 FS delivers unmatched bass performance with precision and reliability.
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.
