The CT SW10, 12 and 15, and the SA1000 dual
subwoofer amplifier are 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 amplifier 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 Installation and Positioning
The CT SW Series subwoofers are intended to be
installed either within existing or custom designed
home theatre system cabinetry close to, or on, the
floor.
If the subwoofer is to be installed within cabinetry it is
important to ensure that the cabinetry is capable of
carrying the weight and that it is structurally reliable.
Significant vibration of the cabinetry panels may
seriously affect the subjective performance of the
audio system. Screw-in rubber feet are supplied for
attachment to the underside of the subwoofer in order
both to protect the cabinet finish and to reduce
vibration.
If the subwoofer is to be installed free-standing on the
floor, it is important to ensure it stands firmly using the
spike feet supplied whenever possible. The spike feet
are designed to pierce carpet and rest on the floor
surface. Initially, screw the lock nuts onto the spikes
enough to leave the nuts floating just above the carpet
when the spikes are resting on the floor beneath.
Screw the spikes fully into the threaded inserts in the
base of the cabinet. If the cabinet rocks when placed
on the floor, unscrew the spike that does not touch
the floor until the cabinet rests firmly without rocking.
Finally, lock the nuts against the cabinet. It may be
more convenient to fit and adjust the spike feet after
speaker positioning has been optimised.
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. That said 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,
the overall system balance can be corrected by
adjusting the volume level of the subwoofer. The more
boost gained from the room, the lower the volume can
