Commentary
Imperial Series speaker system.
The Imperial series Imperial I, Imperial II, Imperial III, and Imperial IV were OEM products of Mitsubishi, so they are very similar in appearance and composition to the diamond tone at that time.
Only Imperial III was distributed in Japan, but this model is configured as if the Super Tweeter was removed from Diatone DS 301.
A 30 cm cone type woofer is installed in the low range.
The mid-range is equipped with a dome type mid-range, and the high-range is equipped with a dome type tweeter.
The network section is equipped with level controls for the middle and high frequencies.
The enclosure uses an acoustic suspension system.
The exterior is finished with a French lacquer using a walnut veneer. In addition, the Sa RUNNET is made with a lattice weave.
