Altavoces Apertura Armonia Evolution

Descripción

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

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.

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.
