Main Construction Features

 

• The large diameter 28 mm voice coil is the right compromise between the lightness of the classic 25 mm coil and the great power management of 32 mm coils. A perfect combination of power and lightness, the necessary for a tweeter that must reproduce frequencies in a linear and faithful way even beyond the threshold of audibility. The coil uses aluminum support to better disperse the temperature.

• Body made of 7000 aluminum alloy and brass, entirely worked by numerical control (CNC). This makes the structure very rigid and with practically zero tolerances to the benefit of consistency of performance and maximum linearity of reproduction, free from any vibration and/or resonance.

• Torcon® soft dome, an exclusive Polyphenylene Sulfide (PPS) with a high-performance fiber that offers superb heat resistance, low weight, and excellent self-damping, gets a free resonance frequency response until over audible frequency. 

• O52 oversized high-quality neodymium magnet. This "engine" guarantees a perfectly linear and constant magnetic flux over the entire working range of the tweeter, guaranteeing an extremely linear and neutral response both at low and high volume. Furthermore, a pure copper ring was added to reduce the harmonic distortions.

• A careful study supported by FEM analysis has allowed us to design the metal parts of the magnet in order to maximize the flow exactly around the voice coil and make it linear throughout the entire excursion. Ventilation is ensured by a large opening on the bottom, protected by a sponge with calibrated holes. This solution also reduces the peak impedance to the resonance frequency making the tweeter easier to interface with any passive crossovers.
