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.
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.
Proprietary « DRIM » structure with a triple attenuation slopes and phase control over the entire bandwidth.
High end components from Jantzen :
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.
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.
