Octa 85H
15" Powered, Two-Way Full Range Multi-Purpose Speaker
Product at a Glance
The British Acoustics Octa 85H is a 15" powered speaker designed for stage monitoring, side fills, and versatile audio applications. It delivers rich lows and crisp highs across 40 Hz to 20 kHz, with wide horizontal and vertical dispersion for consistent coverage in medium to large venues. Powered by a Class-H amplifier and 24-bit DSP, it provides precise voicing and system protection. Built with a durable birch plywood enclosure and scratch-resistant polyurea finish, it includes M10 flying inserts, a 35mm pole socket, and rubber feet. Its matte black grill and acoustic foam combine sleek aesthetics with optional weather covers and flight cases for portability and outdoor use.
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.
