Commentary

This is a limited production model with improved sound quality and texture of SX-LT55.
The details have been improved to adjust and improve the sound quality.

A 14.5 cm Almio Bricone type unit is used for the low range.
The surface is plated with pure gold for for sound quality. At first glance, it looks like the middle and low frequency band. However, the oblicorn section uses a thickness of 120 μ m with double strength, and the magnetic circuit uses an Alnico magnet with a 12000 Gauss pot yoke.

A 14.5 cm Almio Bricone type unit is used for the upper and lower part of the mid and low range.
The surface has tuning of sound quality by pure gold plating, the edge uses foam rubber (foam rubber) edge, spider suspension, etc., and the magnetic circuit uses an inner magnetic alnico magnet magnetic circuit with a 12000 Gauss pot yoke.
Natural characteristics are obtained by arranging the driving axes to face each other at the closest position, setting the tweeter between them, and arranging it called oblique omni array in which each does not interfere.

A 1.9 cm pure gold plated aluminum hard dome unit tuned based on the unit used for the Super Tweeter of SX-L7 is adopted for the high band.
For the magnetic circuit, an internal magnetic circuit of rare-earth neodymium magnet of up to 12000 Gauss is adopted.

Each unit has an aluminum die-cast frame.

Each cabinet has an independent structure. By staggering the tuning frequency of the twin woofer and bass reflex port, the low-frequency playback band is widened and the impedance peaks are dispersed.
In addition, the front baffle has a beautiful wood grain of White Sicmore sticking board, and the other side has a maple sticking board not only on the outside but also on the inside to adjust the sound quality, and the exterior is finished with a glossy coating.
In addition, in order to disperse resonance, the plate thickness has been changed to 25 mm for the front baffle, 21 mm for the top and bottom sides, and 18 mm for the back side to suppress unnecessary vibration.
Insert nuts are embedded so that insulators and spikes can be used as an option.

Each part of the network is carefully selected, and the crossover frequencies are set to emphasize the centrodesmus range of music.
The input terminal uses a bi-wiring method and can be driven by a bi-amplifier.

There is a brass plate with a number engraved on the back.
Also attached is the standard data with the signature of the laboratory technician.
