Mounting the speakers
For optimum performance, it is important that the speakers are firmly and securely mounted. All the speakers may
be mounted directly at floor level, but, as mentioned above, it can be beneficial to raise the position of the surround
speakers and, if the screen is high, it may also be beneficial to do the same with the front speakers. In that case,
the supporting structure for the speakers should be substantial. If constructed of wooden studding, the framework
should be arranged to be directly beneath the feet of the speaker. (figure 6)
All the speakers are equipped with roller glides on the base panel. These allow the speakers to be easily pushed
into place in custom furniture. In order to position the speakers accurately, we suggest you create circular recesses
15mm (5/8 in) diameter in the support surface to locate the glides.
To avoid rocking when the speakers are in position, it is important that these recesses are accurately positioned and
a foot-positioning template is supplied for this purpose.
The shaded area at the front of the template is to allow clearance for the movement of the bass cones. For the CT8
DS, the side-firing drive units require free acoustic access into the listening room, indicated by the shaded area of
the template extending round the sides. The CT8 DS will normally have the front half of the cabinet protruding clear
into the room. It may, however, be built in to a false pillar, but this must be acoustically transparent at the sides, as
well as the front, as indicated by the shaded area.
If the speakers are to be inset in a false wall, a front template is provided for guidance in cutting the aperture. The
template is the same size as the speaker, so remember to leave some clearance. The height of the template includes
the roller glides.
If the speakers are to be mounted in custom furniture, you should also ensure that it is substantially built and
not prone to induced vibration. It should be braced where necessary and it may be beneficial to glue bituminous
damping pads, similar to those used in motor vehicles, to large unsupported panels. Such pads need to be thicker
on wood than metal and a minimum of 6mm (1⁄4 in) should be used.
