6 Introduction and Positioning
Naim loudspeakers are precision acoustic instruments that will only achieve optimal
performance if installed and set up carefully. Please read these instructions before
unpacking, installing and using the loudspeakers. Please also retain the packaging for
future use.
The performance of any loudspeaker will be influenced by
the room in which it is located and even small changes of
loudspeaker position can significantly influence the sound.
Choose a site where the loudspeakers can be located
between 1.2m and 4m apart (4ft and 13ft), clear of room
corners, and where each loudspeaker is between 10cm and
45cm (4" and 18") away from a solid rear wall. The
distance between the speakers and the rear wall is the
aspect of positioning most likely to require adjustment as
you become familiar with the characteristics of the
loudspeakers in your room.
Loudspeakers, like many hi-fi components, will take time to
stabilise and "run-in" and can be expected to improve with
use even over a period of weeks. For this reason it is
prudent not to finalise loudspeaker positioning until the
system has been operating for at least one week.
6.1 Unpacking SL2
To minimise the risk of accident and damage,
components should be removed from the packaging one
speaker at a time and in the
following order. Components
referred to in the following
paragraphs can be identified
through diagram 6.4.
Remove the central packing
piece and Tweeter Suspension
Assembly. Separate the two
and place the
Suspension Assembly
side.
Remove the card shield
containing the Grille. Place the
Grille to one side. Also remove
the card packing piece that
protects the curved top of the
Upper Cabinet.
Carefully lift the
Cabinet out of the carton and
place it to one side. Take care
not to damage either the drive
unit or the aluminium plate on
the underside of the cabinet.

Now lift the
caps out of the carton. Stand it on the floor,
lowermost, and remove the top foam end-cap. Turn the
cabinet upside down being careful not to damage the
aluminium plate. Finally remove the sprung foam end-cap
by pulling its sides outward and lifting it over the plinth.
6.2 Assembling and Installing SL2
Stage 1
With each
be fitted. Screw a spike and lock-nut into each threaded
hole in the plinth. If the loudspeakers are to stand on a
thick carpet, leave a generous length of spike protruding
past the lock-nut. If they are to stand on thinly carpeted or
plain floor, the spike length should be reduced. In either
case, best results will be achieved when the spike length is
set to the minimum required for the spike lock-nuts to sit
just above the carpet pile.
