Planar Magnetic Drivers

By

Definition: A planar magnetic driver is a type of speaker used for midrange and treble that is made of a thin-film diaphragm stretched over a frame and sandwiched between an array of very strong magnets. The thin-film is similar to Mylar, although various manufacturers use different materials. The voice coil is spread across the thin-film. The interaction between the thin-film and the magnets causes the diaphragm to move, thus creating sound. A planar magnetic driver is similar to a ribbon driver, although a ribbon driver is made of a thin-film of aluminum placed between two powerful magnets.
Pronunciation: plan'-are mag-net-ic drivers
Also Known As: PMD
Examples:
Planar magnetic drivers produce highly detailed sound and can handle lots of power.
