Field Coil Speakers & Full-Range Drivers
Field coil speakers represent the most advanced form of loudspeaker motor design, offering unmatched control, dynamics and tonal realism. Unlike permanent magnet drivers, field coil drivers use an external power supply to energize the magnetic field, resulting in superior precision and adjustability.
At Lii Audio, we design and manufacture high-efficiency field coil full-range drivers for audiophiles seeking natural, coherent and emotionally engaging sound.
What is a Field Coil Speaker?
A field coil speaker replaces the traditional permanent magnet with an electromagnet powered by an external supply. This allows precise control over magnetic flux, improving sensitivity, transient response and overall musical realism.
- Adjustable magnetic field
- Higher efficiency and dynamic range
- Improved tonal accuracy
- Superior micro-detail and presence
Why Choose Field Coil Drivers?
Field coil technology is often considered the ultimate solution for high-efficiency loudspeaker systems. It offers a level of control and musicality that conventional drivers cannot achieve.
- More natural and organic sound
- Better coherence across the frequency range
- Enhanced low-level detail
- Exceptional performance with tube amplifiers
