Setup

The nuBox stereoboard AS-225 is a high-quality, very neutral stereo 

active 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 pos-

sible, please observe the following general installation instructions:

With some distance to the wall you can 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 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.

Ideal horizontal listening area

You will get the best sound directly in front of the AS-225, but due 

to the extremely good dispersion characteristics, a balanced sound 

image is achieved even in a relatively wide listening angle range to 

the left and right of this position.

The right height of the speaker

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, for example, the nuBox AS-

225 stereoboard is placed directly under your television set, this is 

already largely fulfilled. If your AS-225 needs to be placed lower or 

higher, it should ideally be angled so that the tweeters are aligned 

with the listening position.
