The FE168SS-HP is a limited release full-range speaker unit newly developed using a development philosophy and proprietary technology that is dedicated to the fundamentals of acoustics. The FE168SS-HP is a limited-edition, full-range speaker unit that has been developed based on a fundamental acoustic development philosophy and proprietary technologies. The powerful, low-distortion, external magnetic circuit consisting of two large ferrite layers and a newly developed cellulose nanofiber coated HP-shaped diaphragm provide powerful yet delicate and expressive music reproduction with a full low frequency range and a straightforward mid-high range sound quality with minimal coloration. Cellulose nanofiber coated HP-shaped 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 been subjected to this treatment, offers a high degree of rigidity and resonance dispersion at a low weight. The full-range diaphragm provides music enjoyment with its fast and sharp low frequency response, full mid-low range, bright and taut midrange, natural sounding mid-high range, and fully extended high frequency range. 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. 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 type low-loss gold-plated terminals are used for input terminals.
This ensures a secure connection of speaker cables and prevents deterioration of sound quality. Nominal Impedance: 8.0 ohm. Mms (M0): 9.54 g.Equivalent Diaphragm Radius (a): 60.0 mm. Voice Coil Diameter:30 mm. Reproduction Frequency Response: fs to 25k Hz. Baffle Hole Diameter: Ø151 mm.
