DRIVE UNITS

  • 18 cm mid/woofer “isotactic matrix” – a woven polypropylene composite cone. This material combines stiffness, lightness and good damping properties.
    Long voice coil for a high linear excursion
  • New generation of ribbon tweeter, using a flat metalized polymer diaphragm.
    Its emissive area is twice that of the Armonia tweeter. A double surface will reduce the movements of the ribbon, and thus the distortion.
    The result is an increase dynamic capacity and a higher resolution

CROSSOVER

  • Proprietary « DRIM » structure with a triple attenuation slopes and phase control over the entire bandwidth.
  • A brand new crossover for the Armonia Evolution with two independent circuits boards for low-pass and High-pass sections.
    Selection of very high end capacitors.
  • Each set of drive units (tweeter and mid/woofer) are individually measured and crossover values adjusted according to these sets measurements.
  • Hand wiring on a 140 µm copper printed circuit board.
  • Optimized crossover structure to avoid magnetic interference between components
  • Bornier en cuivre pur, plaqué argent.

ENCLOSURE

  • This new model uses the Apertura very specific cabinet shape: two curved sides of different length and no parallel front and back panels.
  • Laminar structure based on multiple thin layers pressure molded.
    Such process creates breaking modes and limit propagation of vibrations.
  • Internal multi-cavity framework to stiffen the structure and create very specific areas where damping materials can be applied.
  • Importance is given to damping treatment to cancel any standing waves. We are using 3 different types of dumping materials.
  • Mechanical grounding: a central cone positioned on the axis of the center of gravity improved vibrations transfer to the floor.
  • New aluminum stands and spikes available. Choice of 2 anodized colors: black or silver.
