A good listening room should be rectangular or rectangular, and the larger the area, the better. Square room? No problem, just put the angular symmetry in the center.
finishing material
Non-woven wallpaper or embossed wallpaper are good choices. They are beautiful and sound-absorbing. But remember not to use it too much, otherwise the sound will become dry and lose the mellow and pleasant sense of space.
Speaker position
The main speaker should be symmetrical. The distance between the two main speakers should not be less than 2m. An isosceles or equilateral triangle is best, slightly bent inward into a figure of eight. The outside and back should be more than 0.3m away from the wall, and the height of the tweeter should be slightly higher than the height of people's ears when sitting.
Power supply problem
Power problems have a huge impact on sound! To use power lines, change the household watt-hour meter to more than 5 amps. Audio, kitchen, lighting, air conditioning and other electricity should be set up completely. Install at least one dedicated line for audio equipment to avoid simultaneous use with other household appliances, reduce clutter and noise, and make the audio-visual effect more perfect.
