FiiO FX17

Advanced Driver Architecture The FX17 is built with an innovative per-side design featuring one dynamic driver, four custom balanced armature (BA) drivers, and eight high-performance electrostatic (EST) drivers. A meticulously tuned five-way crossover evenly distributes energy among all drivers, ensuring each component operates at its optimal state for a grander soundstage and natural, lifelike audio reproduction. Electrostatic Driver Innovation Eight carefully implemented electrostatic drivers per side deliver an exceptionally airy high-frequency extension—easily reaching up to 50kHz. Although their inherent sensitivity is only 99dB/mW (compared to the typical 110dB/mW of BA and dynamic drivers), the FX17’s design employs multiple electrostatic units to increase sound pressure levels. This strategic approach overcomes the natural “masking effect” (the ear’s reduced sensitivity to high-frequency sounds in the presence of powerful low frequencies), ensuring that the high and ultra-
