  • dramatic, energetic sound with a very wide soundstage
  • hear every detail, but no fatigue
  • very easy to listen to

Ribbon Tweeter

Has a Planar Magnetic Tweeter due to the tracks in the foil.  The foil is only 20 milligram and 11 mikron thick, so it has 50 times less mass in comparison to a conventional dome tweeter.  This means virtually no resonances or distortion.  The breakup point is at 82 KHz.  The result is a clear, natural sound.

TD mid- and bass drivers

The membrane is a 5 layer sandwich construction: aluminium cone, ceramic, tantalum, diamon and diamond on the back.  All these materials bring in their own strengths to the mix, making this a truly unique and revolutionary drive unit.  1.5 carat of diamond on each drive unit, yet only 10 microns thick.  The TD layers reduce resonance with 36dB over ceramic and is 50 times stiffer than ceramic only membrane.  The breakup mode has been elevated to 20KHz.

The motor comprises of a very strong magnet (N52 Neodymium) with an unseen even magnet field, coupled with an underhung titanium voice coil.  This gies perfect transient response with no measurable distortion.

The turbine shape with excellent aero dynamic capabilityies results in very clean and uncoloured sound.  All edges in the nearby hasket are rounded to eliminate reflections and direct the waves into the dampening material also the complete driver construction is open around the membrane to let it "breathe".

The Crossover

Hard, direct wiring is used with integrated Nordost cables in the crossover itself.  All internal wiring is done with Nordost Norse cables which builds on Valhalla technology with a possible updgrade to TSC from Odin.  The simplest crossover design was made to ensure a direct and pure signal path.
