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.
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.
