The process of choosing nearfield monitors should be easy. - After all, they only have one job to do. The job of monitoring. Not enhancing, not diminishing, not in any way altering the source material.

Enter the Fostex NF-Series. A range of nearfield monitors which deliver a sound completely lacking in those ‘enhancements’ and ‘characteristics’ often found in other studio speakers.

A natural sound, uncoloured and accurately defined, even at high sound pressure levels, allowing you to accurately pinpoint and analyse all aspects of your creative output whilst minimise listening fatigue.

Features NF-4A

  • 10 cm woofer unit that uses the next-generation shape "HR diaphragm" to suppress unnecessary resonance. Equipped with the largest magnetic circuit in its class, reproducing low frequencies that exceed the size of high speed / low distortion.
  • Pure magnesium tweeter, excellent responsiveness without the peculiar habit of metal. The "ridge dome" shaped diaphragm suppresses unnecessary peaks by distributed resonance naturally reproducing the mid-high range with a large amount of information.
  • High-rigidity enclosure using 24mm (baffle) / 18mm thick plywood. In order to eliminate the adverse effect of the internal sound pressure, the amplifier part is rigidly mounted on the backboard of 18mm thickness.
  • Equipped with a high output amplifier with a total output of 95W (low range 60W, high range 35W). The ideal drive system is realized by the digital / analog composite Bi-AMP.
  • Built-in low-cut filter considering low-frequency fog when using a subwoofer, it can be widely used for various installations / uses.
  • EQ dip switch which can adjust high region correction, low region correction, attenuation characteristic of a low cut filter, etc. is carried.
  • The tweeter level can be adjusted within a range of ± 3 dB.
  • AC 240V Power Only
