2.77.1 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.

2.8SURROUND 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. (figure 18)

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
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.

3.2HTM1D
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.
Screw in the feet with locking ring attached, with either the spikes or rubber tips outermost, according to the type of
floor surface. Leave the tips of the feet protruding beyond the inner packing pieces for clearance when the speaker is upright.
After rolling the cabinet onto its feet and lifting off the carton, remove the inner packing and adjust the feet as described in section 3.3

3.3ADJUSTING 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)
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.
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)
Finally, tighten the locking ring against the boss, again using the metal bar. (figure 24)

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)
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.
Screw the lock nuts fully onto the feet and the feet fully into the base. (figure 25)
Stand the speaker upright and adjust the feet to take up any rocking.
Finally, tighten the locking rings against the threaded inserts. (figure 26)
