Commentary
This 3-way speaker system fully expresses Sansui's sound creation policy by making full use of new technology.
A 25 cm cone type woofer is installed in the low range.
This unit uses a magnetic circuit with a large 12 cm ferrite magnet and 100% kraft pulp corn paper with high Young's modulus.
The middle area is equipped with a 12.5 cm cone type squaker.
The large back cavity prevents interference with the woofer and suppresses the generation of cross modulation distortion.
A horn type tweeter is installed in the high frequency range.
An e-type ferrite core with a large gap is used for the network, and DC resistance is kept to 0.3 Ω or less.
In addition, it has 3-step level control for middle and high sound.
The enclosure -density particle board is used for the enclosure, and it is a bass reflex system with ダンプド pipe duct.
The exterior has a walnut finish.
