Description
 
The 3 way speaker system developed as a succeeding model of Sandwich300.

A 20cm sandwich cone Woofer is adopted as low-pass.
In this unit, the off site of a voice coil is dumped using an adhesive substance, and the distorted occurrence is prevented.

A 10cm plastic cone type unit is adopted as a mid range, and adhesive dumping material is applied to the cone.
Moreover, the special-shaped hole was made in cone paper, and coloring of play sound is lost as much as possible.

The tweeter which used a 2.5cm polyester film dome is adopted as a high region.
Since the dimension of an oscillating object is small, the directivity is improving.
