The birth of Ktêma

To be able to communicate, using the language of music, those feelings that cannot be narrated with the most private of words – this is my task.

I am Ktêma, a loudspeaker.

I am a fusion of the old, enduring experience with the light, free, searching spirit. My birth came about by chance, by the strange destiny of the simplest things that fascinating us – the things that give life to great passions and enthusiasm.

It was because of a mysterious string of events that a simple phrase – written in pen along the margin of a wiring diagram – began to represent the inception of an arduous project. Little by little, it took form and depth, generating my conception.


With fine craftsmanship and technical innovation, respecting the ideal continuity, Ktêma embraces the past in a new way, making a further contribution to enhancing the ecstasy of the musical experience.

Geometry: four-way topology, five units. The two low-frequency radiators are compression-loaded and room-interfaced at the lower part of the rear of the enclosure. Above the “fusion” frequency, the mid-high cardioid radiators reproduce the significant part of the spectrum, at the top section of the front of the cabinet.

The cabinet is a rigid, triple arch-shaped structure. The two lateral front cheeks are concave, while the woofer compressor is convex.

The tweeter is a well-established and time-proven 28mm soft-dome unit, created by Ragnar Lian, one of the greatest Danish masters of transducer design.

The midrange array consists of two custom-made 4in units in a stepcompensated baffle, in a cardioid acoustic-resistance configuration, for the most accurate reproduction of the musical perspective.

The woofers are custom-made 9in metal cone, piston performanceoptimised units, in a compression-controlled and room-interfaced configuration.

The crossover is a mutational variable slope, coherent spatial radiation design.

Yter pure Silver-Palladium mono-wiring used throughout.
