Coiled Exponential Bass Midrange Horn Loudspeakers which are each characterized by a rigid cabinet of selected size having a sealed air chamber in the base thereof for receiving a low frequency speaker, or driver, and a coiled or convoluted, exponentially flared sound passage extending from the air chamber to the top of the cabinet. In a most preferred embodiment, a high frequency horn is mounted in the cabinet near the open top to extend the audio range of the loudspeaker system. The combination of a low frequency driver and a high frequency horn separated by a continuously exponentially expanding or flared, coiled or convoluted, multi-tapered sound passage chamber eliminates the need for a midrange speaker or horn.
