HK Audio recently rolled out the largest product launch in the firm’s 35+ year history at this year’s Prolight + Sound in Germany. In the last year, HK Audio has taken on a number of new audio specialists, and this new team has been instrumental in the development of the new pro audio range.

The COSMO integrative line array system family, which is comprised of three different system models, was developed under the premise of offering a flexible and easily configurable solution in the professional PA sector. With horizontal directivities of 100°, 80°, and 60°, this family of loudspeakers will provide the bandwidth needed to cover the most diverse live scenarios.

CONTOUR X is a new point source PA flagship series designed to offer high sound pressure levels from compact solid birch multiplex enclosures. CONTOUR X features modern woofers, 24 dB crossovers and newly developed horns with extra wide mouths, which reduce unwanted distortion and increase the maximum usable SPL by several decibels.


The new C SUB subwoofer series – made up of the C SUB 118 and the C SUB 218 cabinets – fits seamlessly with all COSMO and CONTOUR X loudspeakers. The efficiency and high load capacity ensure large dynamic headroom down to the lowest frequency ranges.

HK Audio first released details of the new EN 54-24:2008-certified VORTIS 2 series at the Integrated Systems Europe trade show in Amsterdam in February 2018. For Prolight + Sound, the entire range of loudspeakers designed for demanding installation projects was on display.

Dipl. Ing. Lothar Stamer, HK Audio’s CEO, says: “With COSMO, CONTOUR X and VORTIS 2, we’re beginning a new chapter in the history of HK Audio, and we’re delighted to be able to unveil these multi-faceted audio solutions for the first time at Prolight + Sound.”

The COSMO C 8 top unit’s 80° horizontal directivity makes it the central building block for a set of mix-and-match systems designed to provide blanket coverage for the entire audience area, with the benefit of HK Audio’s proprietary Multicell Transformer technology. Matched 6.5, 8 and 10-inch loudspeakers will feature prominently in forthcoming COSMO modules to back up the Multicell Transformer’s HF performance with assertive low-mid range response.

COSMO components are not only tuned to harmonize acoustically; they are also engineered for a perfect physical and mechanical fit. Every top unit shares the same 60 cm x 45 cm footprint so individual components are easily connected without having to fuss with hardware adapters. These units fit right on top of one another, so there is no heavy lifting, twisting and turning to be done to set up a system. The array’s curvature can be adjusted in advance on the dolly, so rigging and flying a COSMO line array is as easy.
