HK Audio is a German manufacturer of professional loudspeakers and PA systems, headquartered in St. Wendel, Germany. The company traces its origins to 1979, when brothers Hans and Lothar Stamer began building loudspeaker cabinets in a small workshop in the Saarland region under the name Stamer Musikanlagen. The HK Audio brand itself launched in 1989 with the release of the P1 system, created to focus specifically on live sound reinforcement separate from the Stamer family's other musical instrument ventures.

The product range spans from compact, battery-powered portable systems aimed at singer-songwriters and small venues to large line arrays used in concert touring and installed sound. Well-known product families include the LINEAR series of active cabinets for bands and mobile applications, the ELEMENTS modular column PA designed for easy transport and setup, the SI SERIES tailored for fixed-install work, and the VORTIS line of high-performance install loudspeakers.

HK Audio designs and engineers its products in St. Wendel, where it also operates an acoustics laboratory and handles most of its manufacturing. The brand is part of the broader Stamer group of companies, which also includes the guitar amplifier brand Hughes & Kettner.

HK Audio has 24 products cataloged on Equipboard, including PA Systems, Speakers & Accessories, and Subwoofers & Accessories.
