@ Crossover frequency switch
Allows switching of the crossover frequency of the sub-
woofer speaker between the upper limit of the low range
(S.WOOFER) and the lower limit of the mid to high range
(FULL RANGE). Theoretically, this setting should be made
considering such factors as the acoustic characteristics of
the vehicle, the speaker being used, and the type of music
being listened to. In practice, experiment and find the
setting that sounds best.
