ARMONIA EVOLUTION

Armonia Evolution


The ARMONIA is the second model in the Apertura range that comes in an alternative and more performing version: The ARMONIA Evolution.

The concept remains unchanged : using the same basis but with the implementation of a bigger ribbon tweeter and a brand new cross-over, we are now able to offer a loudspeaker which surpass the performances of our best seller, ARMONIA.

Armonia Evolution has also a new cabinet design, making this new speaker even more elegant. And as for all other models, great attention is given to the smallest details.

SPECIFICATIONS

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.

  • 5 different standard finishes available: SSatin: cherry, High Gloss: Piano black, White, Rosewood, Figured maple. On demand : High gloss and metal high gloss.
