Installation

The subwoofer has been designed both for Home
Theatre installations and to augment the bass
performance of 'full range' speakers in
2-channel audio systems. All audio installations require
some thought in installation if they are to reach their
full performance potential and this manual will guide
you through the process.
The subwoofer requires connection to the mains
power supply, so it is important that you familiarise
yourself with the safety instructions and heed all the
warnings. Keep this manual in a safe place for future
reference.

Subwoofer Applications
The primary function of a subwoofer is to reproduce
signals from an audio-visual processor Low Frequency
Effects (LFE) channel. In addition, the processor may
be configured to divert the low bass portion from
some or all of the other channels and add it to the LFE
information. This is usually done by selecting "small"
loudspeakers in the processor set-up procedure.
In 2-channel audio applications a subwoofer is used to
extend the bass response lower than that provided by
the satellite speakers. The subwoofer low-pass filter
should be set so that the subwoofer takes over as the
output of the satellite speakers falls.
Subwoofer Positioning and Installation
The ear poorly perceives the source location of low
frequency sound so the position of subwoofers in the
listening room is generally less critical compared to
full-range speakers. However, best results are usually
obtained if the subwoofer is placed between the left
and right speakers or in the vicinity of one of them. If
two subwoofers are used, it is best to put one near
the left and one near the right speaker. Placing a
subwoofer behind the listening position, even in multi-
channel surround sound installations, generally results
in inferior imaging, but may be an acceptable
compromise if domestic considerations dictate.
As with all speakers, the proximity of room boundaries
affects the sound of a subwoofer. Bass volume
increases as more surfaces come into close proximity
with the speaker. Unlike full-range speakers, however,
