Picture of DS 203
Commentary

This speaker system inherits the design philosophy of the DS 205, which uses a large-capacity enclosure to stretch out a small-diameter woofer.

A 16 cm cone type woofer using an aramid cloth diaphragm is mounted in the low range.
The aramid cloth diaphragm is made of an aromatic polyamide organic fiber aramid as a cone material and has a two layer structure that eliminates resin and other binders, which were conventionally used in terms of moldability and airtightness. As a result, weight reduction and reduction of inherent sound are achieved.
In addition, the use of HD (High Damping) suspension and ADMC-m magnetic circuit realizes medium range reproduction with low distortion and thickness.

A 4 cm cone type tweeter is installed in the high range.
B for the diaphragm4Uses C (pure boron) and is shaped into a 4 cm cone shape that matches well with a 16 cm woofer.
Artificial leather is attached around the tweeter unit to suppress unnecessary vibration and primary reflection of sound waves.

The cabinet has a volume of 60 liters, the bass reflex port has a larger diameter, and the use of reinforcing bars has been eliminated as much as possible to achieve a smooth and relaxed sound.
Similar to the DS 205, the sides have a large round shape. The side plates are made of laminated R-plywood that goes around from both sides to the front and back. Thus, while ensuring high strength, vibration support points are distributed throughout the cabinet against vibration from the unit. Moreover, by minimizing the diffracted sound waves emitted, it is possible to reproduce sound without turbidity. These side plates are made of natural wood materials that are cross-laminated into a large diameter R-shape and are heated and molded over a long period of time. Strength and shape stability are improved.
In addition, by using Canadian maple for the inner joint part, it has acquired a beautiful sound.

A large gold-plated speaker terminal for banana plug is used for the rear terminal.
The DS 203 has a 4-input configuration for bi-amplifier and bi-wiring.
