Introduction
The CWM Cinema 6 is primarily intended for home
theatre application as a centre channel speaker but it
may equally well be used as front left and right or
surrounds or for 2-channel audio.
No matter how good the speakers themselves, they
will not deliver their full potential unless properly
installed. Please read through this manual fully. It will
help you optimise their performance.
The CWM Cinema 6 speaker may be installed during
construction of the studwork wall or at a later date. If
possible, installation during construction of the wall is
preferred however the CWM Cinema 6 pre-mount kit
will be required.
Speaker Positioning
Check that there is no conflict with other installations
(pipe work, air conditioning, power cabling etc.). In
existing drywall construction, use a stud-finding tool to
map the construction accurately and a pipe detector
to scan the proposed installation position.
Refer to the section drawing of the speaker and ensure
that there is enough clearance behind the plasterboard
(sheetrock) for the clamps to swing out fully.
Avoid installing the speakers in the same cavity as
flimsy ducting, which may be induced to rattle.
The speakers are designed to operate satisfactorily in
a wide range of cavity volumes, ideally above 20 litres
(0.8 cu ft), so make sure the volume is not too
restricted by cross studs.
2
In solid wall construction, be prepared to provide a
cavity in the wall that extends outside the boundaries
of the speaker's frame, otherwise bass performance
will be compromised.
The speakers are balanced for half-space mounting
(ie flush in a wall, ceiling or soffit). Placement near a
wall/ceiling junction or in a corner may give rise to too
much bass and a boomy quality to the sound. Try to
keep the speakers at least 0.5m (20in) from wall/ceiling
edges.
The following sections give guidance on optimum
positioning, but this may be modified in line with
domestic constraints.
Home Theatre Centre Channel Applications
The ideal position for a centre channel speaker is
behind the centre of the screen, however this can only
be realised when using an acoustically transparent
projection screen. In most cases the centre speaker will
be positioned in a laterally central position either directly
above or directly below the screen. Choose the position
that is nearest ear height. Figure 1 illustrates these
positioning guidelines.
Home Theatre Front Channel Applications
and 2-channel audio
For multi-channel home theatre the left and right
speakers should be approximately 0.5m (20 in) to the
left and right of the screen and as near the centre
height of the screen as possible. Figure 2 illustrates
these positioning guidelines.
Best imaging for stereo is obtained when the speakers
are mounted in the wall approximately at ear height and
making an angle between 40º and 60º at the centre of
the listening position.
Home Theatre Surround Channel
Applications
The speakers should be positioned 60cm (2 ft) or more
above head height.
5.1 Channel: The horizontal angle to the centre of the
listening position should be approximately 120º round
from the centre of the screen. Figure 3.1 illustrates this
arrangement.
6.1 Channel: Position two speakers to the sides in line
with the centre of the listening area and one centrally
behind the listeners Figure 3.2 illustrates this
arrangement.
7.1 Channel: Position two speakers to the sides in line
with the centre of the listening area and two behind the
listeners, subtending an angle of approximately 40º.
Figure 3.3 illustrates this arrangement.
Stray Magnetic Fields
The speaker drive units create stray magnetic fields
that extend beyond the boundaries of the cabinet. We
recommend you keep magnetically sensitive articles
(CRT television and computer screens, computer
discs, audio and video tapes, swipe cards and the
like) at least 0.5m (20 in) from the speaker. LCD and
plasma screens are not affected by magnetic fields.
