Commentary
A 3-way speaker system with the style and look of the 4312 Series but with a reduced desktop size.
A newly developed 13.3 cm white cone woofer is mounted in the low range.
This unit uses a paper cone diaphragm and an accordion pleated edge that increases the amplitude linearity of the cone. In addition, an aluminum die-cast frame is used for the frame.
The mid-range is equipped with a 5 cm cone type mid-range, and the high-range is equipped with a 1.9 cm dome type tweeter using a Lipsless pure titanium dome diaphragm.
The mid-range and high-range are equipped with three independently adjustable attenuators.
By adopting a magnetic shielding design, the effect on CRT is suppressed.
The enclosure uses a bass reflex system.
Can be mounted on walls or ceilings by using a separately sold mount Plaquette.
There was also a 4312M3 package with 3 units of 4312M (1 set of 3 units ¥ 96,000).
