Product at a Glance

The British Acoustics Delta D3 LA is an advanced line array speaker system, designed for high-fidelity sound reproduction in professional settings. It offers a frequency response of 65 Hz to 22 kHz and a peak SPL of 141 dB, driven by a powerful 6kW multichannel Class-D amplifier. This model features dual 8” LF drivers with neodymium magnets and an 8” MF/HF coaxial planar wave driver, ensuring accurate and powerful sound delivery. The system is housed in a durable marine birchwood cabinet with a powder-coated grill, and is equipped with a 2.8” IPS control interface. Connectivity includes USB, dual Ethernet, and multiple audio inputs


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.
