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
