Ktema Loudspeaker

“Ktêma eis aei”

The Greeks said, “Ktêma eis aei”:
a possession for ever - something that,
over time, cannot be disputed.



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.
