The easiest way to adjust the spikes is to remove the loudspeaker from the stand and place it
somewhere it cannot be damaged.
Set the stands in their initial position in the listening room. Please refer to figure 7 for guidance on
positioning. Place a soft clean blanket next to the stand and lay it on its side on the blanket. Set the
two spikes at the back and the left hand front spike to protrude approximately the same amount - within
1 or 2mm. If the spike is stiff use a 13mm spanner to turn it. The spike should be screwed in about
10mm to ensure it is firmly located in the stand base. Tighten the locking nuts (A, figure 6)
by hand
.
Set the right hand front spike to protrude the same amount, but do not tighten the locking nut. Set the
stand back on its spikes.
To check that the stand is sitting squarely on the spikes:
1.
If the stand can be rocked in the 10 o’clock to 4 o’clock direction
, lean the stand
to the left and screw
out
the right hand front spike by the amount of movement you
saw. Set the stand back upright and repeat the process until it is sitting squarely on all
four spikes. Lean the stand to the left again and lock the nut on the right front spike (A,
figure 6), taking care not to change the spike’s setting. Lock the spike nut by hand. Do
not use excessive force, as this may damage the loudspeaker base plate.
2.
If the stand can be rocked in the 2 o’clock to 8 o’clock direction
, lean the stand
to the left and screw
in
the right hand front spike by the amount of movement you saw.
Set the stand back upright and repeat the process until it is sitting squarely on all four
spikes. Lean the stand to the left again and lock the nut on the right front spike (A,
figure 6), taking care not to change the spike’s setting. Lock the spike nut by hand. Do
not use excessive force, as this may damage the loudspeaker base plate.
Listening Room Layout
The following points will help you to optimise your listening room layout.
1. The left and right sides of the room should be symmetrical. If the room is asymmetrical, this will
degrade the quality of the stereo image. This is because most of the sound energy that you hear is
reflected before it reaches your ears.
2. Place the loudspeakers symmetrically in the room, i.e. the same distance from the centre line of the
room and the same distance from the front wall.
