The FT3's large dynamic driver also has other benefits. For example, due to its large size, the diaphragm is capable of bearing higher output power, leading to less distortion under large dynamic signals. Also, the larger driver is more easily able to produce lower frequencies for deeper reaching bass.
Features:
The diaphragm is one of the most important parts of a dynamic driver. And not just any diaphragm material can meet the demands of the FT3 due to the large driver size. After countless testing at FiiO, a beryllium-plated gasket + DLC diaphragm was chosen.
The FT3 driver gasket is plated with beryllium. This not only results in a lighter gasket (and thus a lighter driver), but also a more rigid gasket better able to
handle the movement of the large dynamic driver for less distortion.
The diaphragm of the FT3 is made of DLC (Diamond-Like Carbon), - which is both highly sturdy and lightweight compared to other diaphragm materials. This means that the FT3 driver is less prone to breakup and thus nonlinear distortion, while also having an extremely extended frequency response and
improved soundstage.
The FT3 was designed with great sound as the primary goal, and features 3500 impedance to achieve that Compared to lower impedance headphones, higher impedance headphones more effectively filter out noise to the listener resulting in a purer sound with higher signal-to-noise ratio performance
The voice coil is made of ultra-fine Japanese copper-clad aluminum only 0.035mm thick in diameter. This finer voice coil allows the driver to better and more quickly follow signals, has anti-interference capabilities, and allows for thunderous dynamics across a wide frequency response range
