Commentary
As an audio-visual system, this speaker system was developed as a familiar speaker that does not adversely affect the TV screen or videotape.
A 23 cm ceramic compound cone woofer is used for the low range.
The diaphragm is a composite structure combining high-rigidity ceramic material and paper cone with moderate internal loss.
A 7 cm cone type skoker made of ceramic, olefin made of ceramic, olefin, and cone is adopted.
JVC's unique W & D technology has been introduced to improve responsiveness and dynamic range in the middle and high range.
A 1.5 cm dome type tweeter with metalized olefin dome is adopted for the high band.
The magnetic circuit of Woofer and midrange is equipped with a canceling magnet. In addition, it is shielded with a showering cover to carefully suppress leakage magnetic flux.
In addition, the tweeter is an internal magnetic circuit to contain magnetic flux.
As a result, we are able to prevent adverse effects on TV sets, video cassettes and other products.
The enclosure is a symmetrical unit configuration with controlled phase characteristics.
