Product at a Glance

The Delta 15 LA is the all new Self Powered High Performance Line Array System from British Acoustics. Leveraging from the success of Delta 40 LA, the new Delta 15 LA has enhanced efficiency, voicing and control parameters. Our signature 8" Low-Frequency Drivers now feature an aluminium demodulation ring for better harmonics and minimal distortion. The amplifier module can now handle 3600W of peak amplification energy and house the new DSP with FIR presets. The Delta 15 LA is here to change the way you tour with your powered Line Array System


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.
