FE168SS-HP

Cellulose nanofiber coated HP diaphragm
The latest technology, cellulose nanofiber coating, forms a coating layer consisting of cellulose nanofibers and mica on the surface of the base layer, which improves Young’s modulus, specific bending rigidity, and sound velocity while suppressing the reduction of internal loss. The HP (Hyperbolic Paraboloid) shape of the diaphragm, which has undergone this treatment, offers a high degree of rigidity and resonance dispersion at a low weight. The full-range diaphragm provides music enjoyment with its responsive and sharp low frequencies, full mid-low range, bright and taut midrange, naturally resonant mid-high range, and well-developed high frequency range.

Large ferrite magnetic circuit
Two large ferrite magnets are used in the magnetic circuit to ensure sufficient magnetic flux density. By adding a copper cap to the pole section, current distortion is reduced, resulting in powerful music reproduction and improved sound quality in the mid and high frequencies.

Highly rigid aluminum die-cast frame
A highly rigid aluminum die-cast frame is used to support the large ferrite magnetic circuit and eliminate unwanted resonance.

● UDRT damper/edge with excellent amplitude response
The UDRT (Up-Down Roll Tangential) shape is used for the damper and edge. This shape is composed of various surfaces, resulting in high rigidity of the overall shape, shifting resonance to higher frequencies and suppressing specific large peaks to obtain smooth characteristics.

Dovetail-less structure
The tinsel wire is pulled out from the voice coil by a direct lead without a dove on the diaphragm, thereby reducing the mass of the vibration system and equalizing the vibration. In addition, the direct lead is pulled out in the rotational direction from the 180-degree position in consideration of symmetry of mass distribution.

Faston 205 gold-plated terminals
Faston 205 type low-loss gold-plated terminals are used for input terminals. This ensures secure connection of speaker cables and prevents deterioration of sound quality.
