ABSTRACT:
A speaker system includes a first, second and third sound radiators with the second sound radiator positioned medially between the first and third sound radiators. The radiators project first, second and third sound vectors respectively, with the second sound vector oriented vertically and the first and third sound vectors directed generally toward each other at angles above the horizontal so as to intersect at an inclusive angle between 90 and 170 degrees. Sound from the first and third radiators impinges on the second radiator so as to cause an echo effect improving sound spaciousness. The first and third radiators are placed at different angles relative to the listener and at different heights as well to improve time delays in the two radiated signals.
