2. Positioning your 800 Diamond or 802 Diamond1. Unpacking Your Speakers
The 800 Diamond and 802 Diamond are very heavy
and we strongly suggest that they are unpacked in
the room in which they are to be used by two people
working together. It is also a sensible precaution to
remove jewellery to negate the risk of scratching the
speakers’ surface nish.
The table above illustrates the component parts that
are packed with the 800 Diamond and 802 Diamond.
In the unlikely event that anything is missing please
contact the retailer from whom you purchased the
speakers.
All grilles attach magnetically. When tting the midrange
grille, rotate it to nd the alignment with strongest pull.
Tweeter diaphragms are very delicate and easily
damaged. Any mishandling of the tweeter grille close
to the unit may result in the grille being attracted into
the diaphragm. For this reason, the tweeter grille is
supplied ready tted and we recommend that you
leave it in place.
The speakers are shipped with roller-glide feet tted
to their undersides to aid manoeuvring them close to
their nal positions. However, thanks to the extreme
weight of the speakers, it is possible for the roller-glides
themselves to leave marks in vulnerable oor surfaces.
It is advisable therefore to protect the oor using an
intermediate layer of carpet or oor tiles, for example,
as the speaker is moved.
Once the speaker is close to its nal position, the roller-
glides can be removed and the adjustable spike or
rubber feet tted. This is described in Section 3.

with these directives. Consult your local waste disposal
authority for guidance.
General Guidelines
In either stereo or home theatre installations, try to
ensure that the immediate surroundings of each
speaker are similar in acoustic character. For example,
if one speaker is adjacent to bare walls while the other
is adjacent to soft furnishings and curtains, both the
overall sound quality and the stereo image are likely to
be compromised.
The location of room boundaries fundamentally affects
the sound of a speaker. As more surfaces come
into close proximity, the speaker’s bass and lower
midrange will become more prominent. At the same
time, the speaker’s stereo image is likely to become
less focussed and portray less depth. The aim when
positioning speakers is to nd a happy medium
between domestic constraints, tonal balance and
stereo image quality. Re-visiting and adjusting the
position of your speakers following initial installation
will probably further improve the sound quality and is
usually worthwhile.
The 800 Diamond and 802 Diamond have an optimum
vertical listening window which is designed to cover the
average ear height range of seated listeners, between
0.9m and 1.2m. If you have very low seating, the 800
Diamond and 802 Diamond adjustable feet enable a
small degree of vertical tilt should this be required. See
Section 3.
