It is the speaker system which improved DS- 34B from sound quality, the ease of using, and the field of a design.

The unit of the 30cm high compliance type which adopted the carved corn is adopted as low-pass.

A 10cm corn type unit is adopted as the inside region.
This unit seals the diaphragm rear completely, serves as an acoustic load type which filled up that air cell with the sound-absorbing material, and is suppressing interference with a Woofer.
Moreover, electromagnetism braking of 85000maxwell is applied to the magnetic circuit.

A 5cm corn type unit is adopted as the high region.
By the suspension of the special synthetic rubber, it has mechanical load type to which machine braking was applied enough.

The level control is carried in an inside region and high regions, and it can be operated from the front.
