Description
 
The speaker system which adopted the Tallboy type enclosure as the base for SCN20.

a basic design and content volume are the same as SCN20, and the retreat zone equivalent to a stand is pure -- it places and sound tuning is given as a base.

The 18cm corn type Woofer is carried in low-pass.
IIn the magnetic circuit which set the length of the gap as 20mm, several usual times, this unit has the structure where the short voice coil of 8mm width moves, and has realized the high linearity and the low distortion.

The 2.5cm soft dome shape tweeter is carried in the high region.

The input terminal of a Woofer / tweeter independence is adopted, and bi-wiring connection and a by amplifier drive are possible.

The large-sized empty core coil and the high proof-pressure metallized polypropylene capacitor are used for the network part.

The aluminum plate of thick meat is stretched and put on the bottom of a cabinet, while preventing harmful resonance, the stability of an installation side is strengthened, and also it is considered as the structure which can also use a spike.
Moreover, an unnecessary vibration is eliminated using a 36-mm-thick baffle board.

The exterior serves as walnut finishing.
