ABSTRACT:
A sound radiating loudspeaker and tubular enclosure combination wherein the tubular enclosure is either formed in a helical configuration or two or more straight tubular sections which interest each other at an angle. In either form the tube is capable of free standing on a supporting surface with a loudspeaker closing the upper end of the tube and angled generally toward a listening area. Also in either form, additional speakers enclosed in shorter tubes may be joined to the main tube with all speakers either in a common plane or in planes at a slight angle to one another.
