Welcome to Bowers & Wilkins and M-1
Thank you for choosing Bowers & Wilkins. When John Bowers
rst established our company he did so in the belief that
imaginative design, innovative engineering and advanced
technology were keys that could unlock the enjoyment of audio
in the home. His belief is one that we continue to share and it
inspires every product we design.

Check that you have:
1. Speaker on table stand
2. Wall bracket cover
3. Wall bracket
The wall bracket and cover are supplied clipped
together. Pull them apart if required for installation.
If you peel off the rubber mat on the underside of the
table stand, you will nd a Torx key that you will need
when making adjustments to the way the speaker is
mounted.
2 Positioning
The speakers may be used in distributed audio
applications, where they are typically mounted more
than 2.5m (8 ft) high on the wall pointing down. (see
Sections 3 & 5)
For other applications, choose where you are going
to place the speakers, using gures 2-6 according to
the type of installation you want.
2.1 2- and 2.1-channel (stereo)
Figure 2 shows a range of angles to a central
listener.
If the angle is less than 40º, you will not get sufcient
left to right separation.
ENGLISH
Figure 1
2-channel
Figure 2
If the angle is greater than 60º, you may begin to
detect a ‘hole in the middle’ effect, especially if
listening away from the centre line. To reduce this
effect, try toeing the speakers in to point towards a
central listener. (See Section 6 on how to adjust the
direction in which the speakers face.)
Either mount the speakers close to ear height or
angle them to point to ear height at the centre of the
listening area.
2.2 Multi-channel home theatre
Mount the front three speakers as shown in Figure
3. The height of the left and right speakers should
be as close to the centre of the screen as possible.
Their distance from the sides of the screen affects
the scale of the acoustic image. 0.5m (20 in) is a
good starting point, but experiment before xing the
speakers permanently in place.
The centre speaker should be near the bottom or
top of the screen, whichever is closest to ear height.
Surround speakers are best placed at least 0.6m
(2 ft) above head height, just like in a commercial
cinema, to achieve a more diffuse effect
2.2.1 5.1-channel
For the two surround speakers, stick as close as
possible to the angle specied in Figure 4. The
proportions of the room will dictate whether the
speakers should go on the side walls or the rear
wall.

2.2.2 6.1-channel
In this case (Figure 5), two of the surround speakers
should be placed in line with the centre of the
listening area and the third directly behind.
2.2.3 7.1-channel
Figure 6 shows the optimum positions if you have
four surround speakers.

3 Moving the ball socket position
You can skip all of Section 3 completely if you are
going to use the speaker in portrait orientation on its
table stand as supplied, or you want to mount it high
on the wall with maximum downward tilt (Figure 7).
Note: To achieve maximum tilt, it is necessar y to
invert the mounting of the wall bracket. (far right)
WARNIN G! This method of xing is
potentially less secure, because gravity
will allow the product to fall if the stem
is not properly tted to the bracket. It is essential
that the tapered ridge of the clamp bar engages
the groove of the stem as shown in Section 5.
You are advised to avoid this method of xing
unless the degree of tilt is absolutely necessary.
B&W Group cannot accept responsibility for any
damage or injur y arising as a result of using this
method.
However, if you want to use it in landscape
orientation – perhaps for centre channel use – or
mount it on the wall in portrait orientation with the
bracket hidden behind the speaker (Figure 8), you
will need to change the position of the ball socket
from the bottom to the centre of the speaker.

3.1 Removing the table stand base
Peel off the rubber mat from the underside of the
base and remove the Torx key.
Locate the key in the cam-lock device and tur n it
anti-clockwise to unlock the stem (Figure 9).
Part the base from the speaker (Figure 10).
3.2 Removing and turning the back cover
Remove the three screws as shown in Figure 11 and
pull the cover away from the back of the speaker.
Rotate the cover through 180º and re-assemble it
to the back of the speaker, now with the ball joint
positioned at the centre (Figure 12). Take care not to
trap any wires.
3.3 Rotating the stem
In all cases, loosen the accessible ball joint securing
screw (A), rotate the stem through 90º and tighten
the screw again. For landscape orientation, leave the
stem in that position (Figure 13).
Figure 9 Figure 10
Figure 11 Figure 12
For wall-mount portrait orientation, where you do
not need maximum downward tilt and want to hide
the wall bracket as much as possible behind the
speaker, loosen the other ball joint securing screw
(B), rotate the stem a further 90º and tighten the
screw (Figure 14).
Use the supplied Torx key.

4 Connecting using the table stand
Remove the rubber mat from the underside of the
base (Figure 15).
Strip back the outer sheath of the cable by 75mm
(3 in) to expose the two inner sheathed wires.
Strip back the positive and negative wires to expose
10mm (3/8 in) of bare wire. If using multi-strand wire,
twist the strands to obtain a neat end.
Feed each wire through the appropriate hole in the
back of the base, observing the polarity coding
as indicated. The wires will follow a channel and
emerge in line with the side holes in the spring
terminals.
Press the ends of the terminals fully and push the
wire into the terminals. Then release the terminal
ends to clamp the wire.
Replace the rubber mat.
5 Fitting and connecting using the wall bracket
WARNING!
Do not attach the speaker to the ceiling. Decide how
the cable is to be routed to the wall bracket – on the
wall surface (from underneath only), chased into the
plasterwork, or inside hollow (drywall) construction.
ENGLISH
Figure 15
If routing the cable inside the wall or in the plaster
layer, install it before xing the wall bracket in place
and leave 50mm (2 in) showing with the outer sheath
stripped back.
Take care to route the cable clear of where the
bracket xing screws will be. For example, if the
cable is chased into the plaster from above, omit the
centre xing screw.
If laying the cable on the wall surface, t the wall
bracket rst. Cable cannot be routed around the
support platform of the bracket when the cover is
in place. There is only one knock-out in the cover
as shown, so the cable must approach from this
direction.
Using a spirit level, offer the wall bracket to the wall
and mark out the xing holes.
Drill and plug the wall as appropriate to the type of
construction (screws and plugs not supplied).
If laying the cable on the wall surface from below,
remove the knock-out at the bottom of the bracket
cover to accommodate the cable.
Strip back the ends of the inner cores of the cable
to expose 10mm (3/8 in) of bare wire and neatly
twist if multi-strand. Connect the wires to the screw
terminals, observing the correct polarity as shown.
Remove the table stand base, following the
instructions in Section 3.1.

Slide the cover up the stem. Make sure the securing
clamp is clear of the stem aperture in the bracket
and push the end of the speaker stem fully into
the aperture. Tighten the two screws through the
securing clamp evenly using the Torx key supplied
until the slack is taken out of the t of the stem.
Check that the tapered ridge of the clamp engages
the groove in the stem. Do not over-tighten.
Slide the cover back down the stem and click into
place on the wall bracket.

6 Adjusting the angle of the speaker
There are two screws next to the ball socket joint at
the back of the speaker that tighten the joint to hold
the speaker in place. It is only necessary to loosen
one of these to free the joint. Indeed, in portrait
orientation, only one screw will be accessible
(Figure 17).
Use the supplied Torx key to loosen and tighten the
screws.
7 Rotating the badge
If using the speaker in landscape orientation, you
will need to rotate the logo badge through 90º. The
badge is spring loaded. Use the plastic lm tted to
the rear of the badge to pull it out and rotate it. After
doing so, remove the lm (Figure 18).
