The Essence of Field Coil
The Lii Audio FC-10 brings the legendary field coil sound into a more compact 10-inch format, delivering the same purity, immediacy, and dynamic expression that define our larger FC series. With a 34.6 Hz resonant frequency, 96.7 dB sensitivity, and an extended response up to 18 kHz, the FC-10 combines vintage-inspired field coil technology with modern precision for breathtaking tonal accuracy.
Engineered with a 38 mm voice coil and 120 mm field coil motor, the FC-10 achieves remarkable control, low distortion, and effortless transient response. It is ideally suited for audiophile-grade open baffle, horn, or transmission line enclosures, where it offers a natural sense of air, texture, and realism—without the need for a crossover.
