Product at a Glance

The British Acoustics Delta D3 LA is a compact and versatile 3-way dual 8" line array speaker system, designed for small to mid-sized venues. As the younger twin of the Delta D2 LA, the D3 LA delivers the same exceptional clarity and performance while catering to applications requiring a more streamlined,space-conscious solution.With its lightweight design and impressive SPL-to-size ratio, the D3 LA is a powerful option for intimate performances, corporate events, houses of worship, and scalable configurations. Manufactured in Europe with advanced technology, it combines precision engineering and robust construction, ensuring consistent performance and durability in demanding environments.

The D3 LA is equipped with British Acoustics’ sophisticated software tools for comprehensive system design and management. The Delta Array Predictor enables precise sound coverage planning tailored to any venue, while the Delta Audio Controller (DAC) offers intuitive, real-time control for seamless integration into complex setups.Tailored for professionals who prioritize portability and flexibility, the Delta D3 LA excels as a standalone system or as part of a larger Delta configuration. Its compact form factor, coupled with its high-performance capabilities, makes it an ideal choice for achieving superior sound in smaller spaces.The Delta D3 LA embodies the hallmark precision and innovation of British Acoustics, providing a reliable, high-quality solution for small to mid-sized sound reinforcement needs.

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.
