Work with corner horn speakers has led to a philosophy that there is a narrow range of optimum size limited by performance on the one hand and cohesion of bass and treble events on the other. In the design of a new speaker system of size smaller than these limits, the horn principle was abandoned for the bass section but continued to be used for the midrange-tweeter functions in the interest of lowest distortion. The bass section is of the enclosure type with a tubular back exhaust, corresponding in principle to the Bass Reflex but differing in the high inertance of the port. Adjusted empirically, the response of the new speaker resembles that of a three-way corner-horn reference system. The new speaker may be used against a wall, but as in all speakers affords best performance in a corner. It may be used for any of the two or three positions of a stereo array, including the bridged or derived center output.
