Commentary
This is a B5 size speaker system that uses a honeycomb flat diaphragm.
A 14 cm honeycomb plane woofer is installed in the low range and a 2.8 cm honeycomb plane tweeter is installed in the high range.
The front baffle has an oval cross section to eliminate the disturbance of frequency characteristics due to diffraction effect.
In addition, by adopting die-cast cabinets, we are taking thorough measures against magnetic shielding.
The woofer and tweeter units are equipped with anti-magnetic measures to prevent their impact on the TV screen.
The input terminal can be selected with impedance of 4 Ω or 8 Ω, and is designed not to impose excessive load on the amplifier even if it is connected in parallel with other speakers.
Equipped with an thermal relay protection circuit to prevent unit breakage due to excessive input.
There are 2 color variations, silver and black.
