Crossover design – getting the signal to  
the drivers with the minimum of  
degradation and blending them  
seamlessly together – has long been  
regarded as something of a black art. For  
this Series, our engineers have taken a  
sideways look at some of the traditionally  
held views of filter design and bent the  
rules a little. The result is imaging with  
unsurpassed perspective and stability.

How to use the manual  
At B&W, we have always followed John  
Bowers' original philosophy of combining  
the art and science of acoustic design to  
create simply a better product, the  
objective always being to get the  
maximum amount of enjoyment and  
fulfilment from listening to music or  
watching movies.  
This manual covers all the passive  
speakers in the 800 Series. Even if some  
of the information does not immediately  
concern you, having it all in one place  
will help you in the choice of extra  
models you may require to expand your  
system at a later date.

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  
from ear height. (figure 5)  
Within the 800 series, the DS8S is the  
only speaker to offer dipole operation.  
In fact, this specialist surround speaker  
has the advantage of offering a choice  
of both monopole and dipole

If you're only interested in audio and not

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

placed directly behind the centre of the

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.

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.

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.

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)

The ear is at its most sensitive in the

single wiring, you connect the cable from  
the amplifier to the terminals that directly  
feed the midrange driver.

CONNECTIONS  
4.2  
800D  
All connections should be made with the  
equipment switched off.  
On delivery, both positive and both  
negative terminals are connected  
together by link plates.  
The terminals accept a variety of cable  
terminations to suit most applications –  
4mm banana plugs, 6mm and 8mm  
Bi-amplification goes a stage further and  
involves the use of two separate power  
(1/4 in and 5/16 in) spades, or bare wires amplifier channels for each speaker. It is  
When single wiring, leave these links in  
position and connect the cable from the  
amplifier to the centremost pair of  
terminals. (figure 34)

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.  
The 4mm hole in the end of the terminal  
post features a collet that may be  
tightened around a banana plug using  
the upper, smaller diameter terminal cap.  
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.  
f Go to section 5.

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.

assign triggers to different inputs; so if,  
for example, you use a multi-channel  
SACD or DVD-A player for music and a  
separate DVD player for movies, you can  
set up a trigger accordingly.  
All models in the range except for the  
DS8S may be bi-wired or bi-amplified. In  
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.  
The relay in the speaker needs a certain  
amount of current to operate, so check  
the specification of your processor first  
before proceeding. You will need to draw  
45mA for each speaker you want to  
switch.  
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.

ANCILLARY EQUIPMENT  
Floor- and stand-mount speakers

Speakers of this ability deserve signals of  
the highest quality. Choose your  
electronic equipment and interconnecting  
cables with care. We can give guidance  
Moving the speakers further from the  
walls will reduce the general level of  
bass. Space behind the speakers also  
helps to create an impression of depth.  
Conversely, moving the speakers closer  
to the walls will increase the level of  
bass.  
In the centre 0 position, the system  
response is nominally flat. The +  
position gives more output, which may  
be required, for example, if the acoustic on what to look for when choosing

dictate that the speakers have to be  
placed more off line than

be used with these plugs removed for  
maximum bass output, but if the bass  
is too heavy due to room effects and  
you cannot move the speakers further  
from the walls, refit the plugs to reduce  
the bass output. (figure 37)  
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  
the signal is normal programme material.

higher the power you use, the less likely  
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 4  
and 8loads. 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

has on the frequency response of the  
speaker to inaudible levels, the

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  
0.1. 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  
midrange grille, replace the plastic  
centre plug of the midrange drive unit  
with the solid aluminium plug in the  
accessory pack. Simply unscrew the  
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  
highly revealing speakers such as these,  
where there may be a significant increase  
in the amount of detail portrayed
