Example 2. Listening Position: All Seats

Adjust the time correction level of each speaker to almost the same level.

1Sit in the listening position (driver’s seat, etc.) and measure the distance (in meters) between your head and the various speakers.

2Calculate the difference between the distance to the farthest speaker and the other speakers.

L = (distance to farthest speaker) – (distance to other speakers)

3Divide the distances calculated for the speakers by the speed of sound (343 m/s (765 mph) at 20˚C).

These values are the time correction values for the different speakers.

Adjusting and Storing/Recalling the Bass Focus

The time difference between the front-rear/left-right speakers, can be adjusted at the same time. With an initial delay of 0.1 ms for each of the 0 to 99 steps, audible time correction can be done.
