Description
 
It is the compact speaker system which prevented leakage flux with the magnet sealed system.

The 20cm corn type Woofer is carried in low-pass.
Urethane rubber is adopted as an edge part and input-proof [ high ] nature and an exact piston motion are realized. Moreover, the material which performed special dumping processing by butyl is adopted as a dust cap, and the improvement of a mid-high-range ingredient is aimed at.

The 5cm corn type tweeter is carried in the high region.
In order to cut low-pass [ unnecessary ], the special rubber damper is used. The treatment cap excellent in the high region characteristic is adopted as a center cap.

The 1.6cm dome shape super tweeter is carried as an object for super-wide areas.

In order to prevent the leakage flux of the speaker which has a bad influence on TV footage, the magnet sealed system which equipped the Woofer and the tweeter with the magnet for magnetic shields is adopted.
Furthermore, also paying attention to the bad influence which the magnetism of television has on a speaker, examination is added also in the position and the direction of a network coil.

AV equalizer which prepared the usual HiFi position and the sound quality compensation function corresponding to visual software etc. is carried.

The enclosure serves as a bass-reflex type which used high rigidity distribution vibration structure.
