Performance of Loudspeaker Whizzers
The auxiliary loudspeaker cone known as a "whizzer" is used to gain high frequency amplitude response in applications where cost or weight constraints prohibit a separate, dedicated high frequency transducer. Usually attached to the front edge of a dynamic loudspeaker voice-coil former at the apex of the main cone, its target performance range is from 5 kilohertz (kHz) to 20 kHz. The functional mechanism of the whizzer is not particularly well understood. Performance prediction is difficult. Related here are test results, laser vibrometer images, anecdotes, and design directions that may aid future whizzer designs and stimulate the development of better design tools.
