A Helmholtz resonator loudspeaker having a capsule shape that may be truncated at one or both ends. When the housing is truncated, dampening material may be added at the truncated portion. Legs or a stand aid in the physical stability and to further assist the acoustics. The resonator tube is located on the interior of the housing chamber with one end opening into the interior concentric with an axis running along the length of the capsule and the other end exiting the housing below the speaker.
