The Fostex FE103E is a 100 mm (4-inch) full-range speaker driver designed for a wide variety of enclosure types, including bass reflex, Transmission Line, Quarter Wavelength, and Back Loaded Horn. It is constructed with an 'ES cone' made from banana plant fiber, contributing to its light weight and responsiveness.
This driver offers a reproduction frequency response from approximately 80Hz to 20kHz, with a sensitivity of 89 dB/W(m). It has a rated input power of 5W RMS and a music power handling of 15W. The impedance is 8 Ohms.
The FE103E features a stamped steel frame, which the manufacturer suggests may benefit from damping. The magnet material is ferrite, and the voice coil diameter is 20 mm. Its Thiele/Small parameters include an Fs of 79.5 Hz, Vas of 6.90 L, and Qts of 0.36.
This driver has been discontinued and replaced by the Fostex FE103En. It is well-suited for DIY audio projects requiring a versatile and capable full-range driver.
