Setup
The nuPro-soundboard AS-250 is a high-quality, very neutral active
stereo loudspeaker. It impresses with an extremely homogeneous,
precise, and “direct” sound reproduction with the finest resolution
in the entire frequency spectrum. However, even an “honest loud-
speaker” is 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 guide-
lines:
Due to the side-facing bass reflex ports and drivers, the AS-250
should be placed at least 5 centimetres from the side wall in order
to ensure trouble-free operation and to avoid air flow noises. More
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 flush with the shelf or protrudes slight-
ly. 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 AS-
250. If you often need to sit off-centre and thus outside the opti-
mum 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 tweet-
er axis, the sound is still homogeneous. If the AS-250 is placed
directly beneath your TV, you will in most cases be within the opti-
mum listening area already. If the speaker needs to be placed low-
er or higher, it should ideally be angled so that the tweeters are
aimed at the listening position. If this is not possible, we recom-
mend compensating with the sound-controls.
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
