illustrated in Figure 4b. Incorrect connection can result
in poor imaging and loss of bass.
To connect the speakers in bi-wire mode using
either the binding post terminals or the Speakon
socket
If the Speakon option is to be used, disassemble the
Speakon plug as shown in Figure 5a and connect one
pair of positive and negative cables to the terminals
marked +1 and -1 and the second pair of positive and
negative cables to the terminals marked +2 and -2.
Ensure that positive cables are connected to the
+ terminals and the negative cables connected to the
– terminals. Incorrect connection can result in poor
imaging and loss of bass. Once the plug is
reassembled it can be inserted into the socket and
locked by twisting clockwise.
If the binding post terminals are to be used, connect
one pair of positive and negative cables to the
terminals marked LF and the second pair of positive
and negative cables to the terminals marked HF.
Ensure that positive cables are connected to the red
terminals and the negative cables connected to the
black terminals as illustrated in Figure 5b. Incorrect
connection can result in poor imaging and loss of
bass.
Ask your dealer for advice when selecting speaker
cable. Keep its total impedance below the maximum
recommended in the speaker specification and use a
low inductance cable to avoid attenuation of high
frequencies.

Fine Tuning
Before fine tuning, make sure that all the connections
in the installation are correct and secure.
If the sound is too bright, increasing the amount of
soft furnishing in the room (heavier curtains for
example) may help balance the sound. Conversely,
reducing the amount of soft furnishing may help
brighten a dull sound.
Some rooms suffer from "flutter echoes" – echoes that
"bounce" between parallel room boundaries. Flutter
echoes can colour the sound of the speakers in the
room. Test for flutter echoes by standing in the middle
of the room and clapping your hands. Flutter echoes
can be reduced by placing irregular shaped items or
non-reflective surfaces, bookshelves, rugs or pictures
for example, on one of the offending walls or floor.
Running-in Period
The performance of the speaker will change subtly
during the initial listening period. If the speaker has
been stored in a cold environment, the damping
compounds and suspension materials of the drive
units will take some time to recover their correct
mechanical properties. The drive unit suspensions will
also loosen up during the first hours of use. The time
taken for the speaker to achieve its intended
performance will vary depending on previous storage
® products
conditions and how it is used. As a guide, allow up to
a week for the temperature effects to stabilise and
15 hours of average use for the mechanical parts to
attain their intended design characteristics.
However, longer run-in periods (as long as a month)
have been reported and there is evidence to suggest
that this has little to do with the speaker changing and
more to do with the listener getting used to the new
sound. This is especially so with highly revealing
speakers such as these where there may be a
significant increase in the amount of detail compared
with what the listener has previously been used to; the
sound may at first appear too "up front" and perhaps
a little hard. After an extended period of time the
sound will seem to mellow, but without losing clarity
and detail.
Aftercare
The cabinet surfaces usually only require dusting. If
you wish to use an aerosol or other cleaner, remove
the grille first by gently pulling it away from the
cabinet. Spray aerosols onto the cleaning cloth, not
directly onto the product. Test a small area first, as
some cleaning products may damage some of the
surfaces. Avoid products that are abrasive, or contain
acid, alkali or anti-bacterial agents. Do not use
cleaning agents on the drive units. The grille fabric
may be cleaned with a normal clothes brush whilst the
grille is detached from the cabinet. Avoid touching the
drive units, especially the tweeter, as damage may
result.
