Onyx 210 XTW
10" Outdoor Coaxial Speaker - IP67


Product at a Glance
The British Acoustics Onyx 210 XTW is a 10" outdoor coaxial speaker designed for powerful, balanced audio in demanding environments. With a high-output coaxial driver and 2" copper voice coil, it delivers 100° x 100° dispersion and clear on-axis response. Housed in an IP67-rated sealed aluminium enclosure with Onyx Terra-Coating, it offers full protection against dust, water, and corrosion. Perforated stainless steel grills, concealed inputs, and shielded screw terminals ensure long-term durability and clean installation. Ideal for commercial, entertainment, and public spaces, the Onyx 210 XTW combines clarity, coverage, and resilience for high-performance outdoor sound systems.
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.
