Commentary
This large-scale floor-type speaker system was developed with the aim of providing sound that is so natural that speakers are not conscious of it.
A 30 cm cone type unit is used for the low range.
For the cone paper, we have developed a slightly thick and hard paper, and the edge uses a cross roll shape.
The magnetic circuit uses 8 magnets and achieves a magnetic flux density of 13,600 gauss.
A full-scale horn with a screwdriver unit using 8 magnets is adopted for the middle area.
Hard duralumin is used for the diaphragm.
Two square horn-type units are used for the high range.
The network uses a specially designed coil of 12dB/oct. utilizing SANSUI's transformer technology.
In addition, it is equipped with 3 point tap-type level control for high band and middle band respectively.
The enclosure is a bass-reflex system using a pipe duct, and a sound-absorbing material is placed inside to reduce interference.
The material is a chip board 21 mm thick with a walnut finish.
