Three-dimensional sound field expression is realized while maintaining the characteristic bright and taut tone.
Well-balanced sound from low to high frequencies and a three-dimensional sound field space are harmoniously combined for attractive music reproduction.


Scheduled to be released in late July 2022

Features

Product Overview

As a global company in the acoustic industry, we at Foster Group have set “contributing to the future society with sound” as our vision, and harmony between our activities and the environment is one of our top priorities. Our environmental philosophy is to contribute to the realization of a sustainable society in all of our corporate activities. The FE series of full-range speaker units, which have evolved with the times and are steeped in Fostex tradition, will be deepened into the FE-NV2 series in order to further promote environmental responsiveness in this era.

Changes from the FE-NV series

●Changed some adhesives to promote environmental responsiveness

Product specifications are now downloadable from our website to reduce paper resources.

Performance and specifications are the same as those of the FE-NV series.

Main Features

Cone paper made mainly from super beaten kenaf.
By mixing long and short fibers of non-wood pulp, it has moderate internal loss and rigidity, and by mixing chemical fibers and ores as auxiliary materials, it improves the propagation speed and achieves high rigidity.

Low distortion in the midrange due to dove-less design
The FE-NV series is now pigeonholed in all bore diameters to reduce harmonic distortion in the midrange.

Pocket-neck damper
The pocket-neck damper system is used to bond the three vibration system components (voice coil, damper and cone paper) on the same circumference. The shape and material of the damper also provide highly linear amplitude characteristics.

● Gold-plated terminals
Faston 205 type low-loss gold-plated terminals are used for input terminals. In addition to providing a secure joint for speaker cables, it prevents sound quality degradation.
