Abstract (en)
A symmetrical electroacoustical transducing apparatus includes a first electroacoustical transducing system (11,12,13,33) having first electroacoustical transducing structure (33) constructed and arranged to transduce spectral components in substantially the full range of audio frequencies. A second electroacoustical transducing system (14,15,31) has a second electroacoustical transducing structure (31) constructed and arranged to transduce spectral components only in the upper range of audio frequencies. The first and second electroacoustical transducing structures (33,31) are relatively displaced and coact to be capable of radiating a composite stereo sound signal when the first electrical transducing structure (33) receives a first electrical signal representative of a first stereo signal with spectral components in the upper frequency range and the second electroacoustical transducing structure (31) receives a second electrical signal representative of a second stereo signal with spectral components in the upper frequency range. <IMAGE>
