First, for high-grade private rooms: the sound must be clean, clear, bright, rich in details, soft and elastic. Because the space in the private room is relatively small and the seats are close to the speakers, if the sound quality of the speakers is rough, it will be harsh, making it impossible for people to sit in the room for a long time, and it will be very difficult to talk and communicate.
Secondly, for small rooms, 8-inch and 6-and-a-half-inch stereos are better, and the speaker unit with this caliber has sufficient intermediate frequency energy to highlight human voice, but the single bass power of 8-inch and 6-and-a-half-inch speakers is lower, which can only meet the needs of small rooms.
Third, for a large private room: If the room space is relatively large and the bass of the music is not deep enough, you can add ultra bass. However, the sound (microphone sound) is best not to enter the subwoofer, because the amplified sound of the subwoofer will be rich, but it lacks a rounded and bright sense of reality, becomes unclear and has no penetrating power, and makes people feel breathless when singing. In addition, if human voice (microphone sound) enters the subwoofer, the low frequency may also howl (commonly known as flying microphone), and the low frequency howling may make the bass unit "retire" in advance.
