Effective Combination of
Subwoofer and Satellite
Speakers
• When the subwoofer is combined with
satellite speakers in a total system, the sound
characteristics produced are like those
shown in the accompanying graph,
depicting the enhancement of the bass
frequencies.
This is particularly effective for reproducing
ground rumbles and other deep sound
effects found in movies.

(interrupter) must be unplugged in order
to completely cut the power supply. When
