Commentary
Top model of floor type speaker system CT series.
A 31 cm cone type woofer is installed in the low range.
The frame of this unit is made of aluminum die-cast to improve the sound quality during large-amplitude reproduction. In addition, a corrugated damper with optimum compliance is used for the damper to greatly improve the linearity of cone amplitude.
Aluminum with excellent heat radiation effect is used for the voice coil bobbin, and heat radiation holes are provided in the bobbin so that it can withstand temperature rise up to 250 ℃.
The cone paper uses a material with an excellent damping effect to eliminate split vibrations that cause colorization of the playback sound. The edge uses a thoroughly examined material and structure to reduce unwanted resonance and improve cone stability.
It is equipped with 20 cm cone type midbus in the middle and low range.
The Midbus has a rear enclosure to eliminate interference with the woofer, and the dump material and special coated cone paper inside the enclosure improve linearity and transient characteristics.
Equipped with 3.8 cm aluminum dome type skoker in the middle area.
A 2.5 cm titanium dome type tweeter is installed in the high range.
The lightweight, high-rigidity 25 μ - thick titanium diaphragm has been adopted for the diaphragm. In addition, input resistance and machining accuracy have been greatly improved by the adoption of the bobbin integrated type. In addition, a special dump structure has been adopted for the diaphragm, yoke, diaphragm and diffuser to eliminate harmful resonance of titanium.
Parts with less error are used in the network section to achieve a more accurate crossover frequency. In addition, parts such as air core or ferrite core coil are laid out with space on the board to eliminate inter-part effects.
6 mm thick for the speaker terminal2Large terminals are used for speaker cables.
The enclosure is made of 42 mm thick high-density particleboards which are butt-plated on both sides to eliminate board deformation and the round corners are made of top-of-the-line wood.
Felt is attached to the front baffle to improve sound quality by absorbing the sound reflected by the tweeter.
There are 2 types of exterior, mahogany and piano lacquer finish.
