Thank you very much for choosing
Nubert loudspeakers.
You will be able to set up your system
without any problems if you read these
operating instructions carefully.
We will explain the operation, connection
and installation so that you can achieve
optimum sound quality and fully enjoy
your new speakers!
The Nubert team wishes you
happy listening!
Mounting the Speaker Grille
First, mount the spacers on the grille (see the separate grille mount-
ing instructions!), then carefully mount the grille on the speaker by
lining up the spacers of the grille with the matching rubber receivers
on the loudspeaker and pushing the grille in place. Be careful not to
scratch the speaker!

Low Temperatures and Sound
When speakers are shipped and delivered during the cold months
of the year, it is imperative that they adapt to the temperature of
the living area. Low temperatures have a considerable influence on
the moving parts of a loudspeaker such as diaphragm, voice coil,
bead and spider. The ability of these components to follow rapid
oscillations or to perform large excursions is thus significantly re-
stricted. This is not dangerous, but “frozen” speakers are far from
their acoustic peak.
Hence our tip:
When your new speakers arrive on a cold winter’s
day, just give them a few hours to acclimatise. Your Nubert speakers
will thank you with the superior sound quality you have come to
expect from us.
Safety Instructions
• Turn off your amplifier before connecting the speaker cables
• Make sure the speaker cables are firmly attached
• Place the speaker in a dry location
• Do not place the speaker in direct sunlight
• Overload protection: the nuLine RS-54 has an internal automa-
tic overload protection fuse, but please be aware that small am-
plifiers can damage your speakers too. At high sound pressure
levels, small amplifiers can start to distort which can damage the
tweeters. If the speakers begin to sound harsh or distorted, turn
down the amplifier to avoid damage to your speakers.
Elastic Bumpers (bumpons)
The bumpons provide firm, no-slip footing for your speakers and do
not leave marks or dents.
Do not mount the adhesive elastic bumpers until you are certain
you want to keep the speakers. The supplied brand-name bumpers
use a strong adhesive and are difficult to remove, especially if they
have been attached to the loudspeaker for a longer period of time.
If you wish to remove them, warm them up with a hairdryer or
similar before removing them carefully.
Whether you should use the larger or the smaller bumpers de-
pends on the application. Please see page 4 “Setup”.
