Reference K Series

The Reference K Series marks the beginning of a new age of sound. Characterised by the classic virtues of the Reference family, a constant drive for innovation and a focus on the fundamental elements of sound,
it strives for ever greater perfection. A perfection that is achieved in an impressively practical way.

Innovative driver technology

The drivers of the Reference K Series have been comprehensively redesigned. To maximise their rigidity while maintaining optimum internal damping, the woofer and midrange cone drivers are now also fitted with a ceramic-tungsten membrane. Not only does this enhance their outward appearance, but it also ensures a precisely controlled swing-in and swing-out behaviour across the whole transmission range. The natural resonance is therefore always outside the transmission range.

Ceramic-tungsten technology

The membranes of the K Series are manufactured in an elaborate process. Up to 20 % of the existing molecular structure of the aluminium cone is transformed into a ceramic structure and refined with tungsten particles. The result is a membrane with an optimum ratio of rigidity to weight and improved inner damping.

Connection terminal

The high quality connection area with four gold-plated screw clamp terminals is suitable for cable diameters up to 10 mm² and special cable shoes. This provides secure connections Crossovers with long-term stability.

Solid cabinet design

The acoustically optimised cabinet with its organic curved baffle offers significantly improved dispersion characteristics. The solid construction of high quality 50 mm multi-layer laminate sets new standards in terms of stability. The characteristic bow shape of the cabinet is created from solid material in a special process.


The crossovers of the Reference 1 K and 3 K speakers discreetly separate the bass, mid-range and treble ranges. Only selected components with no tolerance are used in the manufacture of their low-resonance circuit
