ABSTRACT:
A mechanical two way loudspeaker includes a low frequency diaphragm arranged coaxially with one another which are driven by the same voice coil. In order to flatten the sound pressure versus frequency characteristic of the loud speaker in the high frequency range, the low frequency diaphragm is provided with a flat sound wave radiation surface. The flat surface may be of a honey-comb configuration, or may be made of a low density synthetic foam.
