Marants LS-6 35,800yen(one-set, around the 1978 time)

The bookshelf type speaker system which Edmond A. May who dealt with LE8T of JBL developed.

A 10 inches (about 25cm) cone type Woofer is carried in low-pass.
Aiming at the cone paper which was equipped with the hardness which can offer an exact oscillation in any cases, the cone Hawley famous as a special manufacture of molding of cone paper was specially ordered to perform is adopted as this unit. The cone of the outstanding hardness which bears 100G is realized by mixing special dye in ten kinds of different fibroid materials, and applying fixed pressure and heat to them simultaneously.
Moreover, the foaming roll edge excellent in flattery nature is adopted as an edge.

The cone type tweeter of 1.75 inches (about 4.5cm) is carried in the high region.
The original phenol resin material is used and the loud sound which stopped the jarring high-end peek is realized.

Considering that a speaker is a compound of a resistor and an inductance, in the network part, the original Kongju gate circuit which considers the impedance characteristic of the network itself as an important point is included, and the flat impedance characteristic is realized in it.

The high-density particle board adoption s Is in the enclosure, and native wood finish is given.

The speaker table lamp was attached as standard.

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. 

Scheme	2 ways, 2 speakers, a sealing scheme, and a bookshelf type
Using unit	For low-pass: 10cm cone type For high regions: 2.5cm dome shape
Impedance	6ohms
Play frequency band	80Hz - 22000Hz
Rated input	40W
The maximum input	80W
Output sound pressure level	84dB/W/m
Cross over frequency	2000Hz
Dimensions	Width 128x height 204x depth of 121mm

Marants LS-5 25,800yen(one-set, around the 1978 time)

The bookshelf type speaker system which Edmond A. May who dealt with LE8T of JBL developed.
A basic design is the same as LS-6, a Woofer is small-caliber-ized, and the enclosure serves as closed mold.

An 8 inches (about 20cm) cone type Woofer is carried in low-pass.
