Tips for better acoustics
1. To achieve better acoustic isolation of the loudspeakers from the floor, some
floor-standing speakers are designed to accept spikes. Use of the spikes can be
advantageous, depending on the living room / floor.
Fitting the spikes
The AURUM floor-standing speakers are fitted at the factory with isolating rubber
dampers between speaker cabinet and base plate. If required, you can swap
these rubber dampers for spikes, which are located in the front parts of the
polystyrene packaging.
Mount the spikes as follows:
a) Lay the speakers on a soft surface
and undo the four Allen screws
holding the base plates using the
supplied Allen key.
b) Remove the base plates and
rubber dampers; unscrew the
corrugated bushes from the four
supplied spikes,
d) Screw all spikes hand-tight into the
threaded sockets provided for this
on the bottom of each speaker
cabinet,
e) Place the base plates in their final
position in the listening area,
f) Insert the four round support discs
in the recesses provided for them
in the base plates,
g) Place the speaker cabinets on the base plates so that the tips of the spikes sit in
the central holes of the support discs.
h) Adjust the lock-nuts of the spikes to achieve precise and equal height
adjustment!
i) Keep any not needed accessory materials safe together with the manual for
possible later use!
2. For better acoustic isolation of centre or bookshelf speakers from the surface on
which they stand, some of these loudspeakers are shipped with 4 self-adhesive
rubber feet.
Care of loudspeakers
Your AURUM loudspeakers are best cleaned with a soft, dry cloth. The aluminium
housing is best wiped in a longitudinal direction with a damp cloth. Do not use
solvents.
You should only clean the loudspeaker systems (woofer, midrange units, etc.)
when they have become very dirty (small amounts of dust have no effect on the
acoustics). Use a soft, dry cloth or a soft brush with very gentle pressure, otherwise
there is a risk of damaging the diaphragms.
We generally advise against cleaning the tweeter diaphragms because they are
extremely sensitive to pressure!
If the silver front frame becomes dirty, spray dry foam cleaner (such as Centralin spray)
onto dirty areas, leave to work in, then simply remove with a vacuum cleaner.
Do not brush off black front frames, instead tap off or remove the dirt carefully with
adhesive tape. On no account clean using anything damp!
The technical details for your product can be found on the back of the speaker
cabinet or on the packaging!
