correction method
Connect an audio frequency signal generator
to a signal input on the subwoofer which has
a main loudspeaker connected to the corre-
sponding “OUT” connector. Set the generator
to 85 Hz. If a signal generator is not available,
then it is possible to use an audio test record-
ing which has a test frequency in the range
70 Hz to 100 Hz. Suitable test signals can be
downloaded at www.genelec.com.
