Abstract
A coaxial loudspeaker comprises a low frequency driver, a high frequency driver, and a magnetic circuit. The low frequency driver is configured to generate low frequency sounds and includes a first voice coil. The high frequency driver, coaxially aligned with the low frequency driver, is configured to generate high frequency sounds relative to the low frequency driver and includes a second voice coil. The magnetic circuit includes a first magnet configured to generate a first magnetic field, a second magnet configured to generate a second magnetic field, a first magnetic gap including magnetic flux from the first magnet and the second magnet in which the first voice coil is positioned, and a second magnetic gap including magnetic flux from the first magnet and the second magnet in which the second voice coil is positioned.
