A Corner Loudspeaker with Coaxial Acoustical Line
A corner cabinet with the loudspeaker coupled to a quarter-wave coaxial re-entrant acoustical line exhibits full acoustical loading at a frequency as low as 38 cps with the volume reduced to less than 2.2 cu ft. The rigidity of the walls being assured by the shape of the acoustical line, the structure of the cabinet can be very light and inexpensive. The lateral resonances of the loudspeaker inherent to tuned loading devices are damped by a series acoustical resistance, which does not affect the power transfer at the desired low-frequency end. The system gives true 36-deg sound distribution in the horizontal plane, independent of frequency. At high frequencies, a large portion of the radiated power is sent to the upper parts of the listening room, enhancing the ratio of the reverberated to the direct sound and meeting more closely the acoustical atmosphere of a concert hall.
