Aluminum Die-cast Frame
This speaker unit, the "FE208SS-HP", is an 20cm Fullrange Limited Unit Released in November 2018 under the FOSTEX brand as a Limited-edition model, priced at ¥55,000(tax included)/1pc. Its main specifications include an Impedance of 8ohm, a Sound Pressure Level (sensitivity) of 94.5dB/W (1m), and a rated power handling of 35W,
To provide reference values for enclosure design, the Lowest Resonance Frequency (fs, f0) is 32Hz, and the Reproduction Frequency Response range is ensured from fs to 23k Hz. Designed as a component for back-loaded horn enclosures, an Mms (m0) of 15.1g, and a Vas of 96.38L. The manufacturer-recommended enclosure type is a Back-loaded Horn.
The frame is made of Aluminum Die-cast Frame, the required baffle hole diameter is Φ186mm, it requires 8 mounting holes, the total net weight is 8260g, the overall diameter of the unit is 230mm,
The FOSTEX FE-SS-HP series is a limited-edition full-range speaker unit developed with FOSTEX's foundational acoustic philosophy and advanced proprietary technology. It features a powerful, low-distortion external magnetic circuit with dual ferrite magnets and an HP-shaped diaphragm with a cellulose nanofiber-coated surface. The diaphragm's coating improves Young's modulus, specific bending rigidity, and sound velocity while minimizing internal loss. The HP (Hyperbolic Paraboloid) diaphragm disperses resonances and ensures both lightweight and high rigidity. This series offers fast transient response, robust low frequencies, rich midrange, and extended high frequencies, providing a highly expressive and enjoyable musical experience.
