The HiFi Five Episode 29:  Field Coil Loudspeakers GUESTS Frank Doris --  Editor of Copper Magazine, Senior Associate Editor at Positive Feedback Rich Pinto -- Founder and Designer, Treehaus Audio Peter Qvortrup -- Founder and Managing Director, Audio Note UK Ken Songer -- Founder and Designer, Songer Audio TOPICS Why are field coil drivers something special sonically? Permanent magnets and electromagnets both generate a magnetic field.  Why does the sound coming off the cone sound different when it's moved by one type of magnet versus the other? What is the technical advantage of using an electromagnet?Are most field coil drivers fabricated in-house or bought off the shelf? Does the type of power supply — tube or solid-state — affect the sound of the driver? How does the sound change as you change the power supply voltage to the electromagnet?  Why? Is there any scenario where a permanent magnet driver is the better engineering choice than a field coil driver for a loudspeaker? Are there any specific objective measurements which demonstrate the technical superiority of field coil drivers? Can you imagine traditional loudspeakers manufacturers like Magico or Wilson moving to field coil drivers?
