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

With fine craftsmanship and technical innovation, respecting the ideal continuity, Ktêma embraces the past in a new way, making a further contribution to enhance 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.

  1. Just had a chance to listen to these beautiful speakers at SOS and boy do they produce such a wonderful and expansive soundstage. Deep and wide and they totally disappear. We did compare them to his Joseph Audio Perspectives, which are an incredible bargain IMO. For the right room the JA would be my choice but if you have a BIG room then the Franco Serblin Ktema’s should be on your short list to hear.

  2. OMG what amazing loudspeakers! Top to bottom just so detailed and FULL sounding. Still out of my budget but I now know what GREAT sound is all about.

  3. Best sound I’ve ever heard PERIOD! I’ve been an electrostatic guy for most of my life but have now been converted.
