Alpine UTX-M08 Product Manual page 18

Conditions:
Farthest speaker - listening position: 2.25m (88-9/16")
Left front speaker - listening position: 0.5m (19-11/16")
Calculation: L = 2.25m-0.5m = 1.75m (68-7/8")
Time correction = 1.75 + 343 * X 1000 = 5.1 (ms)
* Sound speed: 20°. 343m / S (765mph)
In other words, setting the time correction value of the left front speaker to 5.1ms can make the distance between
the left front speaker and the listener be the same as that between the listener and the farthest speaker. Time
correction eliminates the difference in time required for the sound to reach the listening position.
The time of the left front speaker is corrected by 5.1ms so that its sound will reach the listening position at the
same time as the sound of other speakers.
