AperturA FORTé

Apertura’s Forté loudspeaker finally provides an answer to the frustration of many owners of high quality, but limited power amplifiers, such as tube or Class A electronics.

It’s the end of compromise.
Forté has a high sensitivity, extension and control of the low register that has never been seen before.
It benefits also from the well-known Apertura qualities: timbre fidelity, very high linearity and three-dimensional recreation of the soundstage.
All this in a compact, understated and elegant design.

Forté is suitable for rooms of at least 25-30m².
As the large diameter vent tube is located on the rear panel, it is recommended to place the speaker 50-60cm away from the rear wall, if possible.

DRIVE UNIT

• Two 18 cm mid/woofer with light light paper cone, filled with reed fibers.
  Long voice coil for a high linear excursion.
• Fabric dome tweeter from the “Ring Radiator” family.
  Very powerful Neodymium magnet circuit for a high sensitivity.
  Very linear bandwidth thanks to the dome profile and the rear damping chamber.

CROSSOVER

• Proprietary « DRIM » structure with a triple attenuation slopes and phase control over the entire bandwidth.
• High end components from Jantzen :
  • Heavy gauge baked inductors
  • Polypropylene capacitors
• Each set of drive units (tweeter and mid/woofers) are individually measured and crossover values adjusted according to these sets’ measurements.
• Hand wired on a 140 µm copper thickness printed circuit board.
• Optimized crossover structure to avoid magnetic interference between components.
• Internal wiring with 2.5mm² OFC copper cable.

ENCLOSURE

• This 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.
• Panels minimum thickness : 25mm.
• Internal multi-cavity framework (4 heavy bracing panels) to stiffen the structure and create very specific areas where damping materials can be applied.
• Very extensive treatment of the internal volume to cancel any standing waves. Three different material are used for this.
• Mechanical grounding : a central cone positioned on the axis of the center of gravity improved vibrations transfer to the floor.

3 differents standard finishes available :

• • Satin : american walnut
  • High Gloss : piano black, white
