Field coil technology dates back to the early 20th century, originating from a time when permanent magnet technology was not sufficiently advanced. Unlike modern permanent magnets, which are static and rely on materials like ferrite or alnico, field coil drivers use an electromagnet to generate the magnetic field. This electromagnet, powered by an external current, allows for a more controlled and dynamic magnetic field, resulting in superior audio performance.

The principle of operation revolves around the Lorentz Force, where the interaction between the magnetic field generated by the field coil and the voice coil current produces motion. This method provides a cleaner, more accurate sound as it reduces non-linearities and distortion commonly associated with permanent magnets.

Field coil technology might seem like an archaic concept, but its resurgence in high-end audio is due to the unmatched transparency and detail it offers. The magnetic field generated is more stable and less prone to variations, ensuring a purer sound reproduction.

Audio Note UK has resurrected this technology to bring audiophiles an unparalleled listening experience. By utilizing field coil drivers, Audio Note achieves a level of sound clarity and detail that traditional permanent magnet drivers simply cannot match. This technology, while complex, is worth the investment for those seeking the highest fidelity in audio reproduction.

Andy Grove, head of Research and Development at Audio Note UK, has been instrumental in reviving and refining this technology. His work focuses on the benefits of using electromagnets in speaker design, including reduced distortion and enhanced linearity, which contribute to a more natural and immersive listening experience.
