Commentary
400 series speaker systems.
In the conventional design method of speaker systems, it is an orthodox method to raise the average sound pressure in the general mid-range by 2 to 5 dB. The shortage of the low-range has been compensated by the bass reflex effect. As a result, the sound quality was attractive when compared at the store, but sometimes it became audible when you brought it to your home for a long time.
The 400 Series is designed to provide rich and natural playback sound even if you listen to it for a long period of time by setting the average sound pressure to 3 to 4 dB lower than that of conventional orthodox speakers, in addition to making the low-frequency to high-frequency flat characteristics.
In addition, through a technical tie-up with bozak Co., Ltd., we have conducted repeated research on the materials and sound quality of bozak speaker corn paper. Based on the results of this research, we have adopted a speaker unit that uses a unique method and determined the degree of mixing and mass.
A 25 cm cone woofer is installed in the low range and a 16 cm cone squaker is installed in the middle range.
A horn type tweeter is installed in the high-frequency range.
A full-scale LC-type network is used in the network section.
In addition, it is equipped with a tone selector, and the sound quality can be adjusted in 4 stages.
The enclosure is sealed and has a walnut urethane finish on the exterior.
In addition, the speaker enclosure and the base part are designed to be separated so that it can be installed vertically or horizontally and can be used as a bookshelf type without the base part.
By combining the 400 Series and the Matching SR Series cabinets, you can use them with the same dimensions as a stereo set.
