Field Coils

An adjustable magnetic system for loudspeakers built around texture, sensitivity, and the presence of live music.

The principle

Magnetic energy, made adjustable.

Field coils were the original magnetic implementations for loudspeakers, before fixed magnets were strong enough to do the job.

Adjustable flux

Adjusted to taste.

Powered by their own supplies, they are ready for the signal and allow the magnetic flux of each driver to be adjusted to taste.

Driver and horn

Ready for the signal.

Correctly implemented field coils can bring higher sensitivity and musical advantages that make even the most exotic low-powered single-ended triodes feel at home.

112 dB

Vista, at the sweet spot

The Vista Field Coil Loudspeaker

The Vista moves from 107 dB sensitivity to 112 dB—the sweet spot—bringing more texture, dynamics, spaciousness, and intimacy as the music dictates.

107 dB

Nika, at 8 ohms

Nika and Ruby Field Coil Loudspeakers

Field-coil Nika designs raise sensitivity to 107 dB at 8 ohms, opening the door to reference-grade low-power tube amplification in real rooms.

High sensitivity is what lets amplifiers this small drive horns this large.
