Commentary
Ti series floor-type speaker system
LE14H-1, a 38 cmSFG woofer with Aqua Plus compound cone, is used for the low range.
13 cm special polypropylene cone unit 104H is mounted in the middle area.
Based on polypropylene, special fillers greatly enhance the synthesis while maintaining the same internal loss as polypropylene.
A 044 ti tweeter using a pure titanium diaphragm is mounted in the high frequency range.
The dome of 25 micron thickness has been realized by the unique technology of blowing the excess flow of high-pressure nitrogen gas. Excellent response has been obtained by combining the diamond edge pattern inspired by Japanese origami work and the reinforcing rib.
It is equipped with a two step switch-type level control for the middle and high frequencies respectively.
The enclosure uses a round baffle to account for diffraction effects, high-density particle board is used, and natural cheek finish is used for the surface finish.
In addition, in order to prevent disturbance of response due to reflection at the grill frame, we have adopted a flooring grill using a unique floating structure.
The input terminal is gold-plated, and the network circuit, parts, and custom wiring materials are designed with an emphasis on sound quality.
