Fostex FE  103 NV 2 - Fullrange Chassis

The cone paper of the NV models is made from a novel kenaf fiber blend. The mixture of long and short fibers made of non-wood pulp, with the addition of chemical fibers and mineral ores, provides increased rigidity and improved propagation speed.

Eliminating the metallic eyelets, which cause balance imbalance and result in non-uniform resonance distribution across the annular vibrations of the cone-shaped diaphragm, has reduced the undesirable harmonic distortion in the midrange.
The proven three-point bonding, in which the voice coil, the damper and the diaphragm are brought together in a ring, allows a direct power transmission.

The gold-plated Faston 205 connection terminal promises lossless signal transmission.
