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!
Out-rigger feet
nuPro oorstanding loudspeakers are delivered with removable
out-rigger feet, these also ensures that the down-ring bass reex
ports have the required distance to the oor.
Important: The loudspeaker cannot be used without the out-rigger
feet being mounted, please read the included quick-start guide for
mounting instructions.
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.

Setup
The nuPro X are high-quality, very neutral active stereo loudspeak-
ers. They impress with an extremely homogeneous, precise, and
“direct” sound reproduction with the nest resolution in the entire
frequency spectrum. However, even “honest loudspeakers” are
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 instructions:
•The distance to rear- and sidewalls should ideally be as big as
possible, we recommend at least half a meter. Some distance to
the back- and side walls also helps prevent an increase in the
bass- and fundamental ranges.
•If the bass reproduction is perceived as being too strong when
the speakers are placed close to a wall, you can raise the lower
cut-off frequency of the speakers, as described on page 8 under
system hp, and/or adjust the bass volume with the bass control as
a “countermeasure”.
•Within horizontal listening angles up to 30 degrees off the hori-
zontal axis, you will experience no signicant change or loss in
sound quality. Only at wider listening angles does the sound lose
its brightness slightly. It is then advisable to point the speakers
towards the listening position.
•The most natural sound is achieved when the tweeters are ap-
proximately at ear level. But even 20 degrees above or below
the tweeter axis, the sound is still homogeneous. If your active
speakers need to be placed lower or higher, they should ideally
be angled so that the tweeters are aimed at the listening position.
