  • Patent number: 5191177
    Abstract: A tube speaker system having a pair of cylinder bass speakers aligned end to end with closed or blind ends in mutual juxtaposition and with speakers mounted in the other open ends which are opposite each other. A support is secured beneath the coaxially aligned speaker cylinders to prevent the cylinders from rolling on their cylindrical walls. Also, the system is provided with means for forming a laterally enclosed sound tunnel that extends the lengths of the speakers in communication with radial openings in the cylindrical walls thereof. The support may take the form of channel-shaped stand atop the sides of which the tubular speakers are mounted. Alternatively, the sound tunnel may be formed by a larger diameter cylinder within which the cylindrical tube speakers are located. In this embodiment the stand may be formed by a flat slab atop which both the larger diameter cylinder and the cylindrical tube speakers are mounted.
