Delta D3 LA
Flagship Powered 3-Way Dual 8" Line Array
Product at a Glance
The British Acoustics Delta D3 LA is a compact 3-way dual 8" line array system designed for small to mid-sized venues requiring high-performance audio in a space-efficient form. Offering impressive SPL for its size, it suits corporate events, houses of worship, and touring rigs. Built in Europe, it features robust construction and advanced DSP integration. Compatible with Delta Array Predictor and Delta Audio Controller, it allows precise coverage and real-time control. Lightweight and flexible, the D3 LA excels as a standalone or in larger Delta systems, delivering the clarity, durability, and portability expected from British Acoustics’ professional solutions.
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.
