Claim 0:
1. A loudspeaker, comprising:
a compression driver having a first diaphragm assembly including a first magnet, and a first diaphragm coupled to a first voice coil, and a second diaphragm assembly including a second magnet and a second diaphragm coupled to a second voice coil; and
a third diaphragm assembly including a third diaphragm coupled to a third voice coil,
wherein motion of the first voice coil generates a first electromagnetic field (EMF), motion of the second voice coil generates a second EMF, and motion of the third voice coil generates a third EMF;
wherein the first magnet generates a first magnetic field and the second magnet generates a second magnetic field; and
wherein interaction of the first EMF and the first magnetic field oscillate the first diaphragm, interaction of the second EMF and the second magnetic field oscillate the second diaphragm, and interaction of the third EMF and the second magnetic field oscillate the third diaphragm.
