Product at a Glance

The Delta 18B, a powered 18" subwoofer by British Acoustics and is our most widely accepted product. Its self-powered feature makes it ideal for installations as it eliminates the need for amplifier racks and power long cable runs. The Delta 18B is also your best companion outdoors, delivering a 135 dB SPL with its integrated 1400W, Class D ÔøΩ DSP Amplifier, ensuring a stable, high SPL performance. Responding to frequencies between 35Hz ÔøΩ 120Hz, Delta 18B can handle high SPL levels with little to no distortion. The Delta 18B is stackable & scalable, and offers a threaded pole base for usage along with our mid-high cabinets


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.
