[Home Theater Network HDAV.com.cn] With the continuous improvement of audio and video technology, multi-channel home theater systems are increasingly entering our lives, and 7.1-channel home theater is currently more popular among high-end home theater enthusiasts. Accepted multi-channel mode system, but how to correctly and scientifically position up to 8 speakers in a 7.1-channel cinema system may plague many home theater enthusiasts. Let us introduce one of the most convenient Positioning calculation method.
Positioning of the left front speaker:
Distance from the Y axis = length of the X axis × 0.18
Distance from the X axis = Y axis length × 0.15
Positioning of the center speaker:
Distance from the Y axis = (X axis length × 0.18) / 2
Distance to the X axis = Y axis/2
Positioning of the right front speaker:
Distance from the Y axis = length of the X axis × 0.18
Distance to the X axis = Y axis - (Y axis length × 0.15)
Left surround speaker position:
Distance from the Y axis = length of the X axis × 0.535
Distance to the ground = Z axis × 0.75
Note: This position must use two-way or one-way sound surround speakers, three-way sound speakers are not applicable
Right surround speaker position:
Distance from the Y axis = length of the X axis × 0.535
Distance to the ground = Z axis × 0.75
Note: This position must use two-way or one-way sound surround speakers, three-way sound speakers are not applicable
Rear surround speaker position:
The distance between the two rear surround speakers is 30cm and is based on the Y-axis/2
Distance to the ground = Z axis × 0.75
Note: This position must use two-way or one-way sound surround speakers, three-way sound speakers are not applicable
Subwoofer placement:
Distance between subwoofer and X-axis (left or right wall) = Y-axis length × 0.039
Distance from the Y axis = length of the X axis × 0.738
The emperor listened to the location:
Distance from the Y axis = length of the X axis × 0.535
Distance from the X axis = Y axis length / 2
The above is the 7.1-channel placement calculation. This result can provide an acoustic-aligned position reference in different spatial directions. After the horn is placed in position, it can be adjusted according to the actual sense of hearing, because our space is impossible. There is no furniture, and sometimes because of the placement of furniture, it may be necessary to sacrifice the best position of the horn.
