d&b audiotechnik is a German manufacturer of professional loudspeakers, amplifiers, and audio system software, founded in 1981 by Jürgen Daubert and Rolf Belz in Korb, near Stuttgart. The company is now headquartered in Backnang, Baden-Württemberg, where it operates out of a converted spinning mill that houses its research, development, and production. d&b is known primarily in the rental, touring, and fixed-installation markets, and its systems are designed around the principle that loudspeakers and the amplifiers that drive them should be engineered as a single integrated whole.

The product catalog spans large-format line arrays such as the GSL/KSL (SL-Series) and the long-running J-Series and T-Series, point source cabinets including the Q-Series, V-Series, and A-Series, the xC column-speaker line, and a family of cardioid and infra subwoofers. These are paired with d&b's own amplifier platforms — the D-Series (D6, D12, D20, D40, D80, D90) — which incorporate DSP, loudspeaker management, and network control. The company also develops software tools like ArrayCalc for system prediction and R1 for remote control, along with the Soundscape object-based mixing platform built around the DS100 signal-processing engine.

d&b systems are widely used at touring concerts, festivals such as Wacken Open Air, theaters, houses of worship, and stadium installations including the Johan Cruyff Arena in Amsterdam. The company's reputation rests on consistent voicing across its product lines, predictable coverage modeling, and the tight integration between hardware and software, which makes it a common specification choice for production rental houses and venue integrators worldwide.
