Fostex GX100BJ Bookshelf Speaker

The Fostex GX-series features a pure magnesium diaphragm tweeter and HR-shaped aluminum alloy diaphragm woofer to deliver pure audio reproduction for a supreme listening experience. The bookshelf GX100Limited features a 4” pure magnesium woofer unit and a 4/5” pure magnesium tweeter for natural sound stage reproduction. 99.9% pure magnesium has lighter gravity and larger internal loss than other metals, which is ideal for the tweeter diaphragm. The ridge dome shape ideally disperses amplitude vibration. World first 4” HR shaped 99.9% pure magnesium diaphragm used for the woofer unit disperses unwanted resonance and maximizes the original features of metal such as high rigidity and fast propagation velocity. CE plywood is used for the front baffle, top and sides and was specially developed for acoustic use, bonding two different boards (Camphor and Eucalyptus) of different stiffness and density. Hand finished Black piano gloss enclosure featuring magnetically attached front grille. Unique MID Controller adjusts the most sensitive range of 1.6kHz to 6kHz with 1dB to -2dB variable level. The signal going through the MID Controller is separated from the tweeter to avoid deterioration of sound quality. OFC (Oxygen-Free Copper) wire is used for internal wiring and the connecting points are covered with gold plated sleeve. Input terminal is machined copper with gold plating.
