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
(eg cathode ray tube televisions or computer
monitors, audio and video tapes and swipe
cards) within 0.5m (2 feet) of the appliance. The
appliance may cause distortion of cathode ray
tube images beyond this distance. LCD and
Plasma screens are not affected.
