Description
 
The speaker system of the compact size which has improved the low-pass play by adopting a pssiveradiator scheme.

The 10cm cone type Woofer is carried in low-pass.
To the diaphragm, the material which mixed two sorts of softwood pulp was adopted as cone paper, and the lightness and intensity of 0.6g are realized simultaneously. Moreover, the magnet of 9,000gauss is carried in the magnetic circuit.

In order to improve the low-pass play which poses a problem with a small speaker, a 10cm pssiveradiator is carried.
The same cone paper as a Woofer is adopted also as the diaphragm of this unit.

The 2.54cm soft dome shape tweeter is carried in the high region.
The cloth of a polyesters system which has moderate softness and hardness in a diaphragm is used, the dumping agent of an acrylics system is applied, and S/N is raised. Furthermore, the high region play is improved by work of a magnetic circuit with the flux density of 9,000gauss and the equalizer which equalizes an oscillation.

LC parallel-type network which chose the coil and the capacitor by tone-quality serious consideration is adopted as a network part.

The aluminum extrusion material which was excellent in the corrosion resistant and the intensity is adopted as a cabinet, and hairline finish and an alumite manipulation are performed.
Moreover, the interior is equipped with the special dumping material which suppresses a harmful vibration.

Since the receiving window of the hook for wall tapestries sticks, a surface-of-a-wall setting is possible.
