Setup
The nuPro-soundboard XS-7500 is a high-quality, very neutral active
stereo loudspeaker. They impress with an extremely homogeneous,
precise, and “direct” sound reproduction with the nest resolution in
the entire frequency spectrum.
However, even an “honest loudspeaker” is exposed to the manifold
inuences of room acoustics. In order to achieve the most natural
and true-to-life reproduction possible, please observe the following
general installation guidelines:
Due to the rear-facing bass reex ports, the XS-7500 should be
placed at least 5 centimetres from the rear wall in order to ensure
trouble-free operation and to avoid air ow noises. Some distance
to the back- and side walls also helps prevent an increase in the
bass- and fundamental ranges.
When placed on a shelf, the best sound is achieved when the front
edge of the speaker is either ush with the shelf or protrudes slightly.
This allows the loudspeaker to radiate the sound freely into the room
and helps to avoid voices sounding like coming through a funnel.
Ideal horizontal listening area
The best listening experience is achieved directly in front of the XS-
7500. If you often need to sit off-centre and thus outside the optimum
listening area, we recommend that you compensate with the sound
controls.
Placing the speaker at the optimum height
The most natural sound is achieved when the tweeters are approxi-
mately at ear level. But even 30 degrees above or below the tweeter
axis, the sound is still homogeneous. If the XS-7500 is placed direct-
ly beneath your TV, you will in most cases be within the optimum
listening area already. If the speaker needs to be placed lower or
higher, it should ideally be angled so that the tweeters are aimed at
the listening position. If this is not possible, we recommend compen-
sating with the sound-controls.
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 inuence 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 signicantly 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 speak-
ers will thank you with the superior sound quality you have come to
expect from us.
Cloth grille
The cloth grille protects the loudspeaker drivers (for example from
curious children who like to press in tweeter domes) and provides a
visual contrast for those who do not like the technical appearance
of loudspeaker drivers. It is carefully placed against the front of the
speaker and held in place magnetically. Please make sure that the
surface of the bafe is not damaged.
With the cloth grill removed, the loudspeaker sounds somewhat
brighter and clearer - the choice is yours!

Mounting the out-rigger feet
Caution!
Be careful not to scratch the loudspeaker!
Don’t let any items fall into the bass reex ports!
Place the speaker upside down on a soft, non-scratching surface!
Place the out-rigger feet over the threaded bushings as shown in the
picture and mount the feet securely with the supplied bolts and hex
key. You can now turn the loudspeaker around, place it on its feet
and adjust the mini-spikes for a level, stable stand.
Mounting kit with one pair of out-rigger feet
Standard mounting: out-rigger feet pointing outwards
Alternative mounting: out-rigger feet pointing inwards.
This method is recommended if the XS-7500 needs to be placed on
a narrow surface or if heavy objects (more than 50 kg’s) needs to be
placed on the soundbase.
