Abstract
Various implementations include loudspeakers. In some particular cases, a loudspeaker includes: a diaphragm; a basket; an electro-magnetic motor supported by the basket and coupled to the diaphragm for driving motion of the diaphragm relative to the basket along a motion axis; a surround coupling an outer peripheral edge of the diaphragm to the basket; and a waveguide coupled to the basket and surrounding the diaphragm. The waveguide has an arcuate inner surface that is complementary with an arcuate outer surface of the diaphragm and extends along a portion of the arcuate outer surface of the diaphragm.
