FOSTEX NF-1

Commentary

A compact monitor speaker system designed as a near-field monitor.

A 16 cm cone type woofer with FOSTEX-original HP (Hyperbolic Paraboloidal) diaphragm is mounted in the low range.
The HP diaphragm has a third order phase structure consisting of a hyperbola and paraboloid, which eliminates the natural resonance that cannot be avoided with conventional diaphragms, and realizes high-speed original sound tracking with high structural strength. The HP diaphragm also realizes wide-range playback.
The diaphragm is made of wood pulp as a base material combined with various new materials such as ultra-high modulus carbon fiber and super fiber PBO. By sublimating the characteristics of wood pulp to a higher dimension, we have achieved a fusion of propagation speed close to that of titanium and internal loss equal to that of PP material.
In addition to the excellent linearity achieved by the push-pull double damper, the UDR tangential edge eliminates the inverse resonance that previously occurred at the edge, making it possible to reproduce without turbidity.

A 2 cm soft dome type tweeter is installed in the high range.
This unit uses a UFLC diaphragm to achieve flat characteristics without peaks or dips and to eliminate unique characters.

Each unit has an anti-magnetic design.

The enclosure is designed for use at the console top with time alignment at the listening point, with the woofer and tweeter positioned in the optimal front-to-back position to achieve ideal phase characteristics, and with sound sources concentrated to accurately reproduce orientation.
In addition, 21 mmMDF material is used in order to eliminate noise turbidity caused by resonance of the enclosure, and a 33 mm thick front baffle is used for the woofer part.

It is equipped with a unique HP sound reflector to control standing waves inside the enclosure.
The HP Sound Reflector provides low-frequency playback by uniformly attenuating the standing wave across all frequencies.

Equipped with a bi-wireless speaker terminal.
