LUXMAN LX55 29,500yen(one set, the November, 1972 release)


The speaker system which miniaturized LX77 further and pursued the quality of sound.

The high compliance type unit of 25cm aperture is adopted as low-pass, and the long voice coil etc. has realized the firm light bass.

A 4cm dome shape unit is adopted as a mid range.
In this unit, while improving a directivity, the modification of a transient and a distorted property is aimed at by suppressing the splitting oscillation with an audio frequency band.
Moreover, it has tied to the bass region smoothly by having lowered fo to the edge sharply by adopting the thing made of cloth, and also carrying out a meltdown.

The direct ring type of the Lux scheme of 3.3cm aperture is adopted as the high region.
This tweeter drives away a splitting oscillation out of an audio frequency band, carries out only a perfect inertia control span, has it, and lengthens a frequency response for a flat to 22000Hz.
The directivity is also the fully examined diaphragm form and the thing which was excellent with the effect of the equalizer.

The network is made into -12 dB/oct.
Moreover, in order to carry out the work united with the impedance characteristic of the speaker unit, for example, to improve relation of a Woofer and a squawker,In order to solve the influence which it has on the peek of the shoulder property by the side of a low cut of the mid range which appears in a speaker load intensity, or the property of fo of a squawker, a network with a peculiar circuitry routing is adopted and relation of sound is made smooth.

Lauan plywood is adopted as an enclosure, the thing of 25mm thickness is used for a top plate and a lower board, and the thing of 18mm thickness is used for the front and the rear 、 sub-.
Reinforcement was put into a front and the back at T character type, it let the reinforcement stick pass on the sub-, the harmful vibration is prevented, and finish is the Shiraki finish.
Moreover, the bond acetate fiber which was excellent in the sound-absorption effect was fully put into acoustic material, and while dumping low-pass, the occurrence of the stationary wave is prevented.
