Delta K15 X
Self Powered 15" Co-axial Wedge Monitor
Product at a Glance
The British Acoustics Delta K15 X is a 15" self-powered coaxial wedge monitor delivering 3000W of Class-D amplification for precise, full-range sound from 50 Hz to 22 kHz. Featuring a neodymium woofer with a 3.5" Duo Copper Voice Coil, it offers deep lows, detailed mids, and crisp highs. Its flat amplitude and phase response with 60° dispersion ensures natural sound on stage. Housed in a compact birch ply enclosure with Fortex™ cones and sloped input plates, it’s built for touring. DSP limiters, Delta Audio Controller, and Delta Array Predictor support reliable, controlled performance for professional stage monitoring environments.
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.
