Evaluation of the correct high frequency polarity
After the loudspeakers have been mounted in the automobile, they are connected with the
included crossover. At first the crossover should be placed in an easily accessible position,
preferably directly reachable from the driver's seat. To recognize the correct polarity as a
rule the operation of one channel (either left or right) is sufficient.
The correct polarity of the tweeter can be evaluated most simply from the volume.
Adjust the volume control so that the music can be clearly heard in its full band width (high,
mid and deep range).
Play a segment of music (about 20-30 seconds) and pay close attention to the
reproduction. Stop the music and reverse the poles of the tweeter on the crossover by
exchanging the connecting cables (plus / minus). Listen to the music segment again and
try to answer the question which of both connections was louder. Repeat the experiment
until you are completely sure.
The louder reproduction shows the correct polarity of the system!
After the polarity has been decided upon tweeter level adjustment should be reconsidered.
Tips:
* In the dark or with closed eyes the sound differences are usually more audible.
* Use a complex instrumental music segment with several acoustic instruments for the
evaluation.
