Illustrated is an articulated, dual coaxial speaker system, shown in cutaway form to reveal its unusual design. It is the standard equipment on every Fisher instrument and combines a 15'' bass speaker with a horn-type high frequency speaker, both equipped with Alnico-5 magnets. This system features smooth response, minimum distortion and exceptional polar distribution and presence. A dividing network is provided to channel the upper treble and overtones to the high frequency unit and middle and low tones to the massive bass speaker. A multicellular horn system is available optionally at additional cost.
Illustrated is the greatest development of the last ten years in fine sound reproduction for the home. It is a multicellular-horn coaxial speaker utilizing two driving units. The larger is designed to handle with exceptional efficiency the first 5-1/2 octaves of he scale. The second unit, small in size, is built with the microscopic accuracy of a fine watch. This mechanism converts to acoustic energy the rapid and delicate pulses of the higher tones and overtones. A nest of eight\ exponential horns diffuses the ordinarily bullet-like higher tones over an angle of eighty degrees! This speaker system is optional equipment on the Fisher.
