1. A waveguide for use in a loudspeaker having a driver and a front baffle, the waveguide comprising:
a frame having a first end region positionable adjacent to the driver in the loudspeaker and a second end region opposite the first end region and positionable adjacent to the front baffle of the loudspeaker when the first end region is adjacent to the driver, wherein the second end region of the frame is symmetric about orthogonal primary and secondary axes of the frame; and
a waveguide insert having:
a first half-horn couplable to a first longitudinal half of the frame, the first half-horn extending from the first end region to the second end region;
a second half-horn removably coupled to the first half-horn and couplable to a second longitudinal half of the frame opposite the first longitudinal half, the second half-horn extending from the first end region to the second end region; and
a divider positioned between the first half-horn and the second half-horn, the divider extending from the first end region to the second end region;
wherein the waveguide insert is asymmetric relative to the primary or secondary axis.
