Planar magnetic speakers use a thin diaphragm suspended between two sets of magnets. When an audio signal passes through the diaphragm, it vibrates, producing sound. This design allows for a more uniform sound dispersion and lower distortion compared to traditional dynamic speakers. These speakers are known for their clarity and detail, making them popular among audiophiles. They typically require more power to drive than conventional speakers, so a suitable amplifier is often necessary. Brands like Magnepan and MartinLogan are well-known for their high-quality planar magnetic models.
