Apertura Audio 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.

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 differents standard finishes available :
  • Satin : light oak, american walnut
  • High Gloss : rosewood, figured maple, piano black, white
