Delta K40 LA
Powered dual 10" Line Array
Product at a Glance
The British Acoustics Delta K40 LA is a compact, self-powered dual 10" line array designed for professional audio applications demanding high performance and ease of use. Ideal for touring, live shows, and fixed installations, it offers a best-in-class size-to-SPL ratio, delivering powerful, room-filling sound without excessive bulk. Equipped with 3000W Class-D amplification, it provides exceptional clarity and output with high energy efficiency. Its built-in DSP enables plug-and-play operation, while the Delta Audio Controller supports advanced configuration and real-time monitoring for larger systems. Constructed from premium Baltic birchwood, the cabinet ensures durability, minimizes resonance, and maintains accurate sound reproduction at high SPL levels. Combining portability, power, and smart features, the Delta K40 LA sets a new standard for professional line arrays.
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.
