Notes The additional cone acts as a speaker up to 10 kHz, this frequency than the small cone gradually replacing the large membrane, and the latter acts as a reflector for the high tone frequencies.
Detail of this speaker is the high efficiency factor corresponding to 14% (normal range 4-6), the lower resonant frequency in air (45 Hz), and the particular impedance (for the time) 7-Ohm voice coil.

Il cono supplementare agisce come diffusore fino a 10 kHz, oltre questa frequenza il piccolo cono sostituisce gradualmente la grande menbrana, e quest'ultima agisce come riflettore per le note alte.
Particolare di questo altoparlante è l'elevato rendimento corrispondente al 14% (valore normale 4-6), la bassa frequenza di risonanza in aria (45 Hz), e la particolare impedenza (per l'epoca) della bobina mobile di 7 Ohm.
