Marants LS-5A 20,000yen( It is 1 set in two sets, around the 1988 time)

The full-scale 2 way speaker system of a compact size.
Since it is small, it is a setting free type which can be used for various destinations.

A 10cm cone type Woofer is adopted as low-pass.
The pulp cone of a special process is adopted as a diaphragm, and the roll edge of high compliance is adopted as an edge.
Moreover, the large-sized magnet and the four-layers volume voice coil were adopted as the magnetic circuit, and the input-proof [ high ] which is not obtained is realized in a two-layer volume.

The soft dome shape tweeter of 2.5cm is adopted as a high region.
The Dacron cross was used for the shape of a dome shape, having carried out heat molding, two coats of an acrylics system dumping agent was twice given on the diaphragm from on the, and uniform form has been acquired.
Moreover, with the Woofer, the big single-layer winding of a merit is conversely adopted as a voice coil, and the strontium ferrite magnet is adopted as a magnetic circuit.
By cutting to a top plate, the high flux density of 11000 gauss is gained.

The high-density particle board by the walnut Veneer-Sheet finish from a north american is adopted as the material of an enclosure.
The R-shaped walnut is collectively used for a corner part.

The screw type is adopted as a speaker termination and the quality speaker cable is also supported.
