It is the speaker system which determined sound quality fully supposing the amplifier and room which are used and with which production of a decent sound was given.

The high compliance type 20cm corn type Woofer is carried in low-pass.

The corn type tweeter of 5cm is carried in the high region.
By applying mechanical braking by adopting a special fabrication rubber damper, and improving fo point, the distorted reduction near a crossover and the instability of impedance were suppressed, and clearer sound quality has been obtained.

The edgeless cabinet is adopted as the enclosure and the directive dip generated in the tweeter part in the conventional enclosure is improved.
Moreover, it is making to become boomy in a port using the sound-absorbing material of the optimum amount into the prevented damped bass-reflex system.
