Canton - Reference 7k - Tower Speaker (Pair)

Canton - Reference Series

Canton - Reference 7k - Tower Speaker (Pair)

For more than four decades of its history, Canton has become famous among audiophiles for not only their meticulous, true German approach to designing acoustics, but also for their bold experiments with non-obvious high-end materials. For years, Canton has relied on Aluminum diffusers for their speaker systems. The Reference K series relies on Tungsten and Ceramic to make the aperture for the medium and low frequency emitters. The result is a solid speaker that produces an entirely unique, bold sound.

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 aluminum 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.

Solid cabinet design

The acoustically optimized 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 elegant, high gloss, “piano finish” surface is applied and polished in a 12- stage process. It gives the cabinets of the Reference K Series a sensation of extraordinary depth. Acoustically optimized, two-part fabric covers with magnetic fastenings complete the exclusive look.

Exclusive cabling

Cabling is reduced to a minimum. The cables themselves are specially developed for the Reference K loudspeakers. The design, with its special core and six twisted individual conductors per phase, ensures optimum sound transmission from the connection terminal to the chassis.

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.
