speaker positioning
standing speakers), or in corners. The speaker drivers
should be at, or a little above, ear level when seated.
If possible, centre your seating area between the
surround speakers.
The final sound will depend on the acoustics of
the listening room and experimenting with speaker
positioning is very worthwhile.
Subwoofer
The location of Logo will affect the overall sound
quality. Placing the subwoofer next to a wall or in a
corner will often boost efficiency and give a cleaner
low bass sound. However, all rooms react differently
and we recommend that you experiment with
subwoofer positioning.
Speaker stands
The more firmly a speaker is held, the better it will
sound. We recommend the use of rigid metal stands
of 40–60cms height. Properly damped types that do
not ‘ring’ when tapped with a pencil (either by virtue
of construction, or because they are filled with dry
silver sand) will bring out the best in a speaker. Ensure
that the stands and/or speakers do not wobble.

The advice given here is a general guideline for setting up speakers.
Refer to the documentation supplied with your speakers for
more precise positioning and installation information, and see

Room acoustics
Your room’s shape and how it is furnished will affect the sound you
hear. For instance, too many bare surfaces can cause reflections that
may add harshness to the sound. Carpets, wall-hangings and curtains
can all help.
If you have a choice of listening rooms, avoid one that is perfectly
square or has one dimension exactly twice another. Such a room can
aggravate resonances that colour the sound.
The closer you place a speaker to corners and the intersection of
wall and floor or wall and ceiling, the stronger the bass output, which
may over-emphasise the bass. Moving a speaker just a few inches can
sometimes make a big difference.
Speaker setup
Proper speaker placement is the key to the best home theatre sound
(see diagram).
As a rough guide, speakers should be placed on rigid stands at about
15cms from the rear wall and at least 60cms from any side wall.
Speakers should never be placed on the floor (unless they are floor-
