Unleashing the Power of Field Coil Purity

The Lii Audio FC-15 is a state-of-the-art 15-inch full-range field coil driver designed for uncompromising audio purists. With its hand-built field coil motor, exceptional 96.7 dB sensitivity, and extended frequency range from 30 Hz to 20 kHz, the FC-15 delivers unparalleled dynamics, speed, and detail. It redefines what a single driver can do—combining vintage field coil magic with modern precision engineering.

Featuring a 38 mm voice coil, ultra-light cone assembly, and large 120 mm field coil motor, the FC-15 offers remarkable tonal richness and lifelike imaging, all without the need for a crossover. Whether installed in open-baffle, horn, or transmission line enclosures, the FC-15 offers a breathtaking sense of scale, air, and immediacy that few drivers can match.
