Example 2: All seats
Adjust the time correction level of each loudspeaker to almost the same.
1. Sit in the listening position (driving position, etc.) and measure the distance (m) between the head and each
speaker.
2. Calculate the distance correction difference between the farthest speaker and other speakers.
L = (distance from farthest speaker) - (distance from other speakers)
These values are time corrected values for different loudspeakers. By setting these values, each sound can
reach the listening position at the same time as the sound from other speakers.
