Use the bottom switch on the front
baffle when selecting between
monopole and dipole modes. In the
• position, the speaker defaults to
monopole. (figure 8)
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)
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.
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.

2.4 5.1 CHANNEL SURROUND
DS8S only
If you are using the DS8S in dipole
mode only, place the speakers on the
side walls approximately 60cm (2 ft)
above ear height and in line with the
centre of the listening area. (figure 11)
If you are using the DS8S and switching
between dipole and monopole modes
for different applications, place the
speakers on the side walls
approximately 60cm (2 ft) above ear
height and slightly behind the centre of
the listening area, keeping the listeners
within the 60º wide null zone. (figure 12)
All models except DS8S
Place the speakers approximately 120º
round from front centre. The shape of
the room will dictate whether they are
placed on a side or rear wall. (figure 13)

2.5 6.1 AND 7.1 CHANNEL SIDE
Place the speakers to the side, in line
with the centre of the listening area.

2.6 6.1 CHANNEL REAR
The rear channel of 6.1 EX recordings
may be reproduced by a single speaker
placed directly behind the centre of the
listening area. (figure 14)
f Go to section 2.8
2.7 7.1 CHANNEL REAR
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.
Place two speakers behind the listening
area to make an angle of approximately
40º to the centre of the listening area.

2.8 SURROUND SPEAKER HEIGHT
If you use the system for movies, place
the speakers approximately 60cm (2 ft)
above ear height. (figure 16)
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.
(figure 17)
For all other models, if you are listening
to audio only and there are only one or
two listeners, mount bookshelf speakers
with the tweeters approximately at ear
height.
If there are more listeners, raise the
speakers just above head height to avoid
obstructing the sound to any listener.

3.1 800D/801D/802D
On delivery, the speakers are fitted with
roller glides to aid movement. Because
of the extreme weight of these speakers,
the rollers can cause indentation of
wooden and other vulnerable floor
surfaces. You should therefore take steps
to protect such surfaces by using an
intermediate layer such as floor tiles or
thick felt. The latter will allow you to glide
the speakers over smooth surfaces if you
push the cabinet low down.
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.
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)
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.
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.
Using the Torx key supplied with the kit,
remove the 4 roller glides from the plinth
of the speaker and replace them with the
feet. (figure 20)
Adjust the feet as described in section 3.3.
f Go to section 3.3.
3.2 HTM1D
Supplied with the speaker are
4 adjustable feet and screws for fitting
them to the cabinet. They have 40mm
(1.6 in) of vertical adjustment, allowing tilt
up to 8º if desired. This is useful, as the
most common situation will be for the
speaker to be mounted on the floor
under a large screen.
The feet are reversible, having a spike for
carpets on one end and a clear rubber
pad for vulnerable surfaces on the other.
Fit the feet during the unpacking
procedure when the underside of the
cabinet is exposed. This allows the inner
packing pieces to remain in place against
the underside of the cabinet as
protection whilst the speaker is rolled
over into the upright position, and be
easily removed afterwards.
First read section 3.3 to familiarise
yourself with the design. If the speaker is
to be tilted back, fit the front threaded
bosses with the cones facing outwards
(figure 21) and the rear ones with the
cones facing inwards (figure 22). This is
as illustrated on the separate sheet
placed in the carton.
