(1) The listening room should not be too small, otherwise a pair (or two pairs) of speakers will not be placed, and the sound image will not be wide enough when shaking. Of course, it is not suitable to put a pair of speakers too wide, which will cause audio and video Scattered. The room capacity is about 3 meters (width), 5 meters (length), 2.8 meters (height). If the output power of the amplifier is strong, the volume of the hall is better.

(2) Rectangular halls are preferred. Generally speaking, the distance between a pair of main speakers (L/R) and a pair of surrounding speakers (V/i) is 2.5-3 meters. The distance between the main speaker and the surrounding speakers speakers can be determined according to the size of the hall, and the ideal distance is 3-4 meters. Therefore, the position between the four speakers is the seat of the “emperor”.

(3) The decoration around the hall should be coordinated “as much as possible” to avoid inconsistent reflected waves and affect audiovisual positioning.

(4) The reverberation time in the listening room is long and the sound is turbid; the short stereo becomes dry. A reverb can of course be used for tuning, but not as good as a natural soundstage.

(5) In order not to affect others as much as possible when enjoying movies and music, and the activities of others will not affect oneself, the listening room must have sound insulation performance.
