Setup
The nuPro A-100 are high-quality, very neutral fully active Hi-Fi/
studio/multimedia loudspeakers (2-way bass reflex system). They
impress with an extremely homogeneous, precise, and “direct”
sound reproduction with the finest resolution in the entire frequency
spectrum. However, even “honest loudspeakers” are exposed to the
manifold influences of room acoustics. In order to achieve the most
natural and true-to-life reproduction possible, please observe the
following general installation instructions:
• The rear-facing bass reflex ports should be at least 3 centimetres
away from back- and side walls in order to avoid air flow noise.
Some distance to the back- and side walls also helps prevent an
increase in the bass- and fundamental ranges. If the bass repro-
duction 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 ad-
just the bass volume with the bass control as a “countermeasure”.
• When placed on a shelf, the best sound is achieved when the front
edge of the speaker is either flush with the shelf or even 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.
• On the bottom of the speaker, you will find 4 threaded M4-bush-
ings, 100 x 100mm apart. These are meant for mounting the
speaker on Nubert speaker-stands or wall-mounts. You can find
compatible stands and wall-mounts on www.nubert.de
•
Caution:
The bushings are intended for the standing, upright
mounting of the speaker, not for hanging the speaker from the
ceiling or any other tensile loads!
• Within listening angles up to 30 degrees off the horizontal axis,
you will experience no significant 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 lis-
tening position or – if this is not possible – use the treble control to
brighten the sound a little.
• The most natural sound is achieved when the tweeter is at about
ear level. But even 20 degrees above the tweeter axis, the sound is
still homogeneous. If your active speakers need to be placed lower
or higher, they should be angled so that the tweeters are aimed at
the listening position.

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 baffle is not damaged.
With the cloth grill removed, the loudspeaker sounds somewhat
brighter and clearer – the choice is yours
