Which manufacturer makes the voice actor speakers?

I am also using the Seiyu S2 speaker. This speaker is made in Shenzhen, China. The factory address seems to be Baoan District, Shenzhen. Objectively speaking, from my experience using this speaker, the sound quality is very good. It has a three-speaker design and two bass diaphragms on the back of the machine. The bass dives deep and is very comfortable for listening to music. The two metal adjustable frequency microphones can It prevents frequency channeling, has the function of canceling the original singing accompaniment, has the Bluetooth function, and can also use the National Karaoke software to link the speakers for National Karaoke. The machine itself is not very heavy and is easy to carry. It is not as bulky as a trolley case. I am personally very satisfied that I can buy such a speaker for a little over 1,000.
