In many systems, a single subwoofer will offer excellent performance, but for the ultimate in
deep bass, we recommend a stereo pair of subwoofers. With two subwoofers the same
connection instructions apply, except that the amplifiers left channel output goes to one
input on the left subwoofer and the right channel output goes to one input on the right
subwoofer. The left main speaker is connected to the left subwoofer and the right main
speaker to the right subwoofer.
Now that your subwoofer is correctly connected, it is time to adjust the volume, crossover
frequency and phase controls on the rear panel.
Semi-passive connection (See fig. 4): The
speaker outputs of an integrated amplifier/
receiver are connected to the speaker
inputs of the subwoofer, which converts
the signal to line-level to drive the sub-
woofer and provide a line-level output sig-
nal to feed the power amplifier which dri-
ves the main speakers. This solution is
more expensive than passive connection,
but allows the use of a more powerful se-
parate amplifier to drive the main
speakers. Try the fully passive connection
to see of it sounds just as good, or even
better.
Passive connection (See fig. 3): The spea-
ker outputs of an integrated amplifier/re-
ceiver are connected to the speaker inputs
of the subwoofer, which converts the sig-
nal to line-level to drive the subwoofer.
This solution should only be used, if no
line-level connections are available. The
main speakers are connected to the spea-
ker outputs of the subwoofer.
