D-307M
Commentary

The D-307 series small speaker system.

A 12 cm cone woofer with an OMF diaphragm is mounted in the lower range. This unit uses an integrally molded S-line edge with an organic connection to the diaphragm to reduce reflection of propagating waves.

A 2.5 cm soft dome type tweeter is installed in the high range.

MDF is used for the enclosure, and a trapezoidal form is adopted to ensure the internal volume while suppressing standing waves.
In addition, it is equipped with 60 mm pitch screw holes for brackets and wall mounting metal fittings on the back.

The input terminal uses a screw-type speaker terminal for banana plug.
