Apertura Edena Evolution 2-way floorstanding speakers

DRIVE UNITS

• 22cm mid/woofer « isotactic matrix » with 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 Edena 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 Evolution.
  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
• Binding post: Pure copper, silver -plated

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.
• Double thickness on the most critical panels
• Woofer frame mechanical locking
• 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 improves vibrations transfer to the floor.
• New aluminum stands and spikes available. Choice of 2 anodized colors: black or silver
