Bass cones throughout now feature a
sandwich construction of carbon fibre
skins bonded to a Rohacell foam core.
Rigid diaphragms are best for
reproducing bass frequencies and this
new construction allows us to thicken the
cone section, without suffering increased
mass. The extra thickness makes the
cone a more effective barrier to any
residual sound generated inside the
cabinet, giving tremendous dynamics and
timing to the bass, with the secondary
effect of cleaning up the midrange.

centre line of the installation. (figure 3)
although the formation of such images is
never quite as precise as it is between
the front speakers.
2
POSITIONING
If you are also using the speakers for
movies, you should try to match the
audio image to the size of the screen.
That generally means that the speakers
should be closer together. A good
starting point is to put the speakers
about 0.5m (20-in) from the edges of the
screen. (figure 4)
Most films are originally balanced for
cinemas, where a large number of
speakers spread around the auditorium
are used to create the surround sound
field. In that case there are more
surround speakers than there are
discrete channels of information and a
less precise image is created that gives
an all-enveloping effect. Dipoles and
similar diffuse speakers are better at
recreating this type of sound field in the
home, but using fewer speakers to do it.
Image positioning with these types of
speaker is never as precise as it can be
with monopoles. However, they do have
the advantage of making it easier to
balance the system for a larger listening
area.
Stray magnetic fields
If you are using speakers in a home
theatre set-up and you are using a CRT
screen (a traditional tube television or
back projector), make sure the picture is
not going to be distorted by stray
magnetic fields from the drive unit motor
systems. The following dedicated centre
speakers are magnetically shielded
because their application requires them
to be placed right next to the screen:
Bookshelf or on-wall speakers should be
placed at a height that brings the
tweeters approximately to ear level. In
the vertical plane, the dispersion narrows
in the crossover region between the
midrange and tweeter drive units, when
both units are working together. To
preserve the optimum sound balance, try
to keep within 5º of this.
HTM1D
HTM2D
HTM3S
HTM4S
All other speakers in the Series should
be placed at least 0.5m (20-in) from such
screens. Some television brands are
particularly sensitive to magnetic fields
and may require extra spacing. Plasma
and LCD screens are not affected and
front projectors are usually well away
from the speakers anyway.
Floor-standing speakers have the angle
of their optimum listening window
adjusted for the height of the speakers
and the typical range of ear height of
seated listeners.
You may well receive conflicting advice
from different sources on the best type of
surround speaker to use. The truth is
that there is no one perfect solution for
all situations and the final choice for any
given application will be influenced by
several criteria, some of which may have
a degree of conflict.

If you have an acoustically transparent
screen, place the speaker behind the
centre of the screen. Angle it towards the
listeners if the tweeter is more than 5º

Within the 800 series, the DS8S is the
only speaker to offer dipole operation.

processor. You may therefore choose
whichever type of operation best suits
the conditions of the listening room, the
size of audience and the type of
programme being played. Indeed, you
may even change the characteristic for
different types of programme and, as
the total energy into the room is the
same in both modes, no recalibration
of the installation is necessary when
switching between them.
If you are just listening to audio, place
the speakers centrally and mount
bookshelf or wall mount speakers with
the tweeters at ear height. (figure 7)
Apart from the dedicated on-wall model
SCMS, the balance of the speaker is
more natural if the speakers are at least
0.5, (20-in) from the rear wall. This also
helps to improve the impression of
perspective. (figure 2)
f Go to section 3.
2.3
SURROUND
In monopole mode, only the two drive
units on the front face operate. In
dipole mode, the front tweeter is
disconnected; the side firing drivers are
brought into operation and the
crossover frequency to the bass unit is
lowered. The drive units on opposing
sides are connected out of phase with
one another, which creates a wedge-
shaped null zone, approximately 60º
wide, at right angles to the wall. If the
listeners sit within this zone, they
become less aware of the location of
the speakers and hear more reflected
sound; hence the diffuse nature of the
sound field.
If you are only concerned with 2-channel
audio, having the speakers further apart
can lead to what is known as the hole-in-
the-middle effect, where it's difficult to
generate a stable phantom central
image. If you have a centre speaker, you
can space the left and right speakers
further apart. All that happens is that the
image widens. It's just like being closer
to the performance.
Surround speakers generally fall into two
main types – those that one might
describe as 'normal' speakers – so-
called monopoles, where the sound
comes from a set of drive units mounted
on the front of the enclosure – and those
that give a more diffuse sound field, such
as dipoles. Each type has its
advantages.
Most multi-channel music is recorded
with home entertainment in mind and is
monitored using monopole surround
speakers, whatever the multi-channel
recording format. This enables better
location of side and rear images,
If you have to space the speakers further
apart because of domestic constraints,
the central image can often be improved
if you toe the speakers in towards the
centre of the listening area. This can also

Bass performance may be enhanced by
using the optional adjustable feet. These
are produced separately in a pack of 4
(800 Series Floor Spike Kit, part no.
FP22359). They have 40mm (1.6 in) of
vertical adjustment, allowing a certain
degree of tilt if desired, and are
reversible, having a spike for carpets on
one end and a clear rubber pad for
vulnerable surfaces on the other.

7.1 CHANNEL REAR
However, if a 12V signal is applied to
the trigger input, internal relays switch
to dipole mode. In the •• position, the
speaker is always in dipole mode,
whatever the trigger signal. (figure 9)
These recommendations may also be
used for a 6.1 channel system using two
speakers at the rear, wired in parallel to
the same channel.
To fit the optional feet, first lay the
speaker down on its side (to avoid
possible damage to terminals or drive
unit diaphragms). (figure 19)
Set the direction of the positive and
negative dipole lobes using the centre
toggle switch marked ’ on the front
baffle. The stem of the switch points in
the direction of the positive lobe.
Place two speakers behind the listening
area to make an angle of approximately
40º to the centre of the listening area.
(figure 15)
Due to the weight of the speaker, this
should be done by at least two people.
Remove rings and other jewellery to
avoid scratching the surfaces and
provide a soft surface such as a piece of
carpet that the speaker can lie on. You
may also like to wear non-slip gloves.
f Continue to section 2.8
For the smoothest panning of sounds
between all the speakers in the
installation, side speakers for all
applications and rear speakers for 6.1
and 7.1 applications should have the
polarity of the lobes set according to
figure 10.
2.8 SURROUND SPEAKER HEIGHT
If you use the system for movies, place
the speakers approximately 60cm (2 ft)
above ear height. (figure 16)
Do not be afraid to handle the speaker
by lifting on the side of the spherical
midrange 'head'. It is a little unnerving,
because the head is flexibly mounted on
the bass cabinet, but it does come to a
stop and is strong enough to take the
weight of the speaker.
This is also the preferred height for the
dipole mode of the DS8S in all
applications, although it may also be
mounted on the ceiling. Try to keep it
around 0.5m (20 in) from the side wall.

For the HTM2D, HTM3S and HTM4S,
the FS-NHTM stand supports these
centre speakers low down so that the
top of the speaker is no higher than
60cm (2 ft) from the floor, commensurate
with positioning them below a large
screen. The stand allows the speaker to
be tilted back by 0º, 4º or 8º.

ADJUSTING THE FEET
The threaded bosses that hold the feet
have a large conical shape on one side
of the flange. For maximum height, fit the
bosses with the conical shape towards
the floor. (figure 21) For minimum height,
have them pointing into the speaker.
(figure 22)
f Go to section 4.
Follow the instructions supplied with the
stand in each case.

DS8S
When mounting the speakers on a
bookshelf, stick the 4 self-adhesive
rubber feet to the base of the speaker.
(figure 27)
The speakers may be fixed to a wall or
ceiling using screws in the range 5mm to
6mm diameter (No.10 to No.12).
Screw in the feet close to where you
think the final adjustment will be, with the
spikes or the rubber ends outermost as
appropriate to the floor surface. If you do
not intend to tilt the speakers, orient the
bosses with the cones inwards and leave
just enough thread exposed to fit the
locking rings. Fit, but do not tighten the
locking rings.
f Go to section 4.
On the back of the cabinet are three wall
plates. The screw head should be
inserted into the round part of the
aperture and slid fully along one of the
slots. The slots are sprung loaded to
prevent the speaker being readily
knocked out of position. The screw
length should be chosen to give a
minimum of 25mm (1 in) engaged thread.
(figure 28)
3.6
SCMS
The speaker is designed to be fixed to a
wall and is supplied with a bracket that
allows adjustment of both horizontal and
vertical angles. (figure 29) The bracket
should be fixed to the wall using screws
in the range 5mm to 6mm diameter
(No.10 to No.12). The screw length
should be chosen to give a minimum of
25mm (1 in) engaged thread. (figure 28)
Stand the speaker upright and adjust the
feet using the metal bar provided to give
the amount of tilt required and to take up
any rocking. (figure 23)
Ensure, especially when fixing to drywall
panels, that the screw length and wall
plug security are sufficient to hold the
weight of the speaker. B&W can accept
no liability for any failure of wall or ceiling
fixings.
Finally, tighten the locking ring against
the boss, again using the metal bar.
(figure 24)
Hold the template provided against the
wall in the desired position and use a
spirit level to line it up properly. The
outside dimensions of the template
correspond to the rear of the cabinet.
Note especially that the centre of the wall
plate does not coincide with the centre
line of the speaker.
f Go to section 4.
Use the template provided to mark the
screw positions. The outside dimensions
of the template correspond to the rear of
the cabinet.

803D/803S/804S
For best performance, screw the
adjustable feet into the threaded inserts
in the base of the speaker as appropriate
– spikes for carpets or clear rubber for
wooden and other vulnerable floors.
(figure 25)
Stick 4 of the clear self-adhesive rubber
pads to the rear panel of each speaker,
one close to each corner. These stop the
speaker vibrating against the surface and
help keep it in position. (figure 30)
Mark the fixing holes on the wall and drill
and plug the wall.
Ensure that the screw length and
wall plug security are sufficient to
hold the weight of the speaker. When
fixing to drywall construction, try to
arrange for the screws to go into a
stud. B&W can accept no liability for
any failure of wall or ceiling fixings.
Lay the speaker down on its side (to
avoid possible damage to terminals or
drive unit diaphragms). Remove rings
and other jewellery to avoid scratching
the surfaces and provide a soft surface
such as a piece of carpet that the
speaker can lie on.
Adjust the protrusion of the screws such
that the rubber pads are a friction slide
on the surface when the wall plates are
hooked over the screw heads. (figure 31)
Always check and ensure that:
Screw the wall plate D to the wall and
test the firmness.

not the same as having a fully active
system, because the speaker's internal
passive crossover is still used.
Important safety notice
When bi-wiring or bi-amplifying, remove
the links after loosening the lower, larger
diameter terminal caps. (figure 35)
In certain countries, notably those in
Europe, the use of 4mm banana
plugs is considered a potential safety
hazard, because they may be
If using bi-amplification, ensure that each
amplifier channel has the same gain,
otherwise you will change the balance of
the speaker. Check the absolute polarity.
Some amplifiers invert the signal, and a
mixture of different types may cause a
dip in the overall response. If you have a
mixture of inverting and non-inverting
amplifiers, reverse the polarity of the
connections from any inverting amplifier
to the speaker.

inserted into the holes of
unshuttered mains supply sockets. In
order to comply with European
CENELEC safety regulations, the
4mm holes in the ends of the
terminals are blocked by plastic pins.
If you are using the products in any
country where these conditions
apply, you should ensure that any
banana plugs cannot be used in an
unsafe manner by children or other
uninformed persons.

DS8S
In addition to the normal speaker
terminals, there is an additional pair of
screw terminals to operate an internal
12V relay that switches the speaker
between monopole and dipole modes
from a remote trigger. (figure 36)
Bear in mind that, even though midrange
and, even more so, tweeter drivers can
(and only need to) handle less
continuous power than bass drivers, the
amplifier feeding them needs to have an
adequate voltage swing in order to
supply the short-term high-frequency
peaks in music without distortion. A high
voltage capability implies high power, so
it is not particularly desirable to have a
lower powered amplifier feeding the
midrange and tweeter than is used for
bass drivers.
Ensure each positive terminal on the
speaker (coloured red and marked +) is
connected to the positive output terminal
of the amplifier and negative (coloured
black and marked -) to negative.
Incorrect connection may result in
impairment of frequency response, poor
imaging and loss of bass.
You cannot use this facility if:
a
Your processor does not feature a
12V trigger at all.
b
Your processor only offers a simple
trigger that outputs a 12V signal when
the unit is switched on. This can only
be used to switch other equipment on
and off at the same time.
Always screw the terminal caps down
fully to prevent rattles.

for example, you use a multi-channel

set up a trigger accordingly.
All models in the range except for the

3-way systems, one set of terminals
feeds the bass drivers and the other the
midrange and tweeter. In 2-way systems,
one set of terminals feeds the bass/
For single wiring, short cables are
provided to link both positive and both
negative terminals together. Each cable
carries a spade connector at one end
and a 4mm banana plug at the other.

amount of current to operate, so check
the specification of your processor first
before proceeding. You will need to draw

midrange driver and the other the tweeter.
When single wiring, connect the cable
from the amplifier to the lower terminals
on 2-way systems (805S, HTM4S,
SCMS) and the upper terminals on
3-way systems.
Separation of the signal paths to each
section of the speaker can improve
imaging and the resolution of low-level
detail, and allows the user to optimise
the cable to the frequency range of use.
The relay in the speaker only works when
the manual switch is set to the monopole
(•) position. If there is no voltage to the
trigger input, the speaker stays
monopole. If a 12V DC signal is present,
the relay overrides the manual monopole
setting and switches the speaker to
dipole mode. If you have the switch set
to the dipole (••) position, the trigger
feature will not work.
On these terminals, use the opposite
type of connector on the link cables to
what you have terminating your main
cable. For example, if your main cable
terminates in spade connectors or bare
wires, use the banana plug end of the
link cables in the same terminals.
(figure 33)
Bi-wiring involves the use of two
separate 2-core cables from the same
amplifier, one to each pair of terminals.
This is the minimum we would
recommend, but should you prefer to
single wire, perhaps during the initial set-
up procedure or because you do not
want to see a multitude of cables in the
room, you must connect both positive
and both negative speaker terminals
together.

Moving the speakers further from the

Conversely, moving the speakers closer

be used with these plugs removed for
maximum bass output, but if the bass

In the specification we recommend a
range of amplifier powers. The higher
figure is defined by the power handling
capability of the speaker. When
calculating the power handling, it is
assumed that the amplifier is not run into
clipping, which distorts the frequency
power spectrum of the signal, and that

you are to experience amplifier clipping.
You can often tell how good an amplifier
is at driving complex speaker loads by
looking at its power rating into both 4Ω
and 8Ω loads. The nearer the ratio is to
2:1 the better, as it indicates a good
current capability.

RUNNING IN
For the most discerning listening, remove
bass and midrange grilles as described
in section 8 – Aftercare.
The performance of the speaker will
change subtly during the initial listening
period. If the speaker has been stored in
a cold environment, the damping
compounds and suspension materials
will take some time to recover their
correct mechanical properties. The drive
unit suspensions will also loosen up
during the first hours of use. The time
taken for the speaker to achieve its
intended performance will vary

impedance of the cable at all frequencies
(measuring both positive and negative
conductors in series) should be kept as
low as possible and certainly below
0.1Ω. At low frequencies, the DC
resistance of the cable is the dominant
factor and you should choose a gauge of
wire sufficient to achieve the impedance
requirements over the length of cable
you need to use. At mid and high
frequencies the inductive component of
the impedance can dominate the DC
resistance. This and other properties
influenced by the detailed construction of
the cable become important. Ask your
dealer for advice on the best cable for
your needs.

If you use these systems without the

centre plug of the midrange drive unit

fitted plug and screw in the
conditions and how it is used. As a
guide, allow up to a week for the
temperature effects to stabilise and
15 hours of average use for the
mechanical parts to attain their intended
design characteristics.
However, longer run-in periods (as long
as a month) have been reported and
there is evidence to suggest that this has
little to do with the speaker changing and
more to do with the listener getting used
to a new sound. It is especially so with
