Abstract: A highly compact loudspeaker which produces high fidelity, omnidirectionally propagated sound from only two sound drivers. The loudspeaker has a cylindrical, sound tight housing in which are mounted a relatively high frequency sound driver and a relatively low frequency sound driver, and optionally, an intermediate frequency sound driver. The high frequency driver is fixed at the top of the cylindrical housing, and is oriented to direct sound upwardly, away from the housing. The low frequency driver is fixed to the housing at the interior thereof, thereby dividing the housing into two sound resonating chambers. The low frequency driver directs sound downwardly into the lower of the two chambers. The bottom of the lower chamber is closed by a floor which bears a crossover network conventionally connected to the two sound drivers. The sound drivers are both coaxially centered within the housing. The loudspeaker optionally has two pairs of input signal terminals and a switch for selecting between the two pairs.
