2. Positioning
FS-805 D4 or 804 D4
FS-805 D4 and 804 D4 are intended to be floor
mounted only. It is important to ensure that they
stand firmly on the floor using the spike feet supplied
whenever possible.
FS-805 D4 and 804 D4 are supplied with both spikes,
(intended for mounting the speaker on a carpeted floor)
and rubber feet (intended for mounting the speaker on
a hard floor).
Note: If the spikes are used on a hard floor, it is
advisable to place a hard protective surface between
the spikes and the floor to ensure that the floor is not
marked by the spike.
In order to stabilise the speaker, initially fully screw
the lock nuts onto the spikes/rubber feet. Then screw
the spikes/rubber feet fully into the threaded inserts
in the base of the speaker/stand. If the speaker/stand
rocks when placed on the floor, unscrew the spikes/
rubber feet that do not touch the floor until the speaker/
stand rests firmly without rocking. Finally lock the nuts
against the base by using the supplied tool to gently
tighten the nut whilst using the supplied bar to stop the
spike/rubber foot rotating.
Note: Take care not to mark the finish of the
speaker plinth or stand base when using the
adjustment tools.

It may be more convenient to fit and adjust the
spikes/rubber feet after speaker positioning has been
optimised in the room. If fitting or exchanging the
spikes/rubber feet, after removing the speaker from its
packaging, the speaker can be carefully lowered onto
its side to ease access to the underside of the base.
It is advisable to place the speaker on a soft, non-
marking surface when lowering it to ensure that the
surface finish is not damaged. Once the spikes/rubber
feet are fitted, the speaker can be lifted into position.
Note: It is advisable that two people work together to
lift the product due to its weight. The speaker should
not be dragged across the floor once the spikes/
rubber feet have been installed as this is likely to
result in damage to both the speaker and the floor.
Speaker Installation
Using Wall Shelves (805 D4 only)
The speaker is primarily designed to be mounted on a
dedicated floor stand (FS-805 D4), but may be placed
on a shelf, although this offers less flexibility to optimise
the speaker's performance. If shelf placement must be
used, we recommend using the foam bung inserts
(supplied) to optimise port performance (see Fine-
Tuning). In both installation cases, the speakers'
tweeters should be approximately at ear height at your
usual listening position.
Note: If using a shelf, ensure that it is strong enough
to properly support the weight and fit the 4 self-
adhesive plastic feet to the underside of the speaker.

Speaker Positioning
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.
Conventional Stereo Systems
To begin with, the speakers should be positioned
between 1.5m and 3m apart at two corners of an
equilateral triangle completed by the listening area at
the third corner. The speakers should be placed at least
0.5m away from the back and any side walls (as per
the illustration above).
Home Theatre Systems
If the speakers are to be used for the front channels
in a home theatre system, they should be placed
closer together than for 2-channel audio, because
the surround channels tend to widen the image.
Positioning the speakers within approximately 0.5m
of the sides of the screen will also help keep the
sound image in scale with the visual image. As with
conventional stereo positioning, the speakers should
ideally be at least 0.5m away from any side walls.
