Overview
FE103NV2 is a speaker unit developed as a successor to the FE103EN. A three-dimensional sound field expression has been achieved while maintaining the bright and strong tone characteristic of the FE-En series. The small caliber blends rich bass and gorgeous mid-high range to make music stand out.

The FE series full-range speaker units, where the tradition of Fostex is alive, are renewed to FE-NV2 series in order to further promote environmental friendliness in this era.
Points changed from FE-NV series
・ To promote environmental responses, changed some adhesives
・ To reduce paper resources, the product specification sheet is to download from homepage
Performances and specifications are the same as prior FE-NV series models.
New cone paper is based on vigorously beaten kenaf fiber. Mixing long and short fibers of non-wood pulp maintains appropriate internal loss and stiffness. By mixing chemical fiber and mineral ore as secondary material, it improves propagation speed and rigidity.
The metallic eyelets used to be added to the diaphragm result in uneven weight balance, causing unequal split resonance in addition to the annular vibration mode possessed by the cone-shaped diaphragm,which causes distortion in the midrange. By eliminating the metallic eyelets new FE-NV series offer reduced harmonic distortion in the midrange.
The pocket neck damper developed in the FF-WK series has been adopted to continue the three-point bonding of the voice coil and the damper and cone paper on the same circumference. The shape and material of the dampers have been reviewed for more linear amplitude characteristic than the current FE-En series.
A low-loss gold-plated terminal with Faston 205 type has been adopted as input connector.
