5. The design of the STEP plus enables them to still produce a clear and precise sound even when
they are positioned closer to a wall. This position broadly reinforces low frequencies by around
+3 and + 6 decibels, making the bass output sound more powerful. As a result, the tonal quality
and authority of the sound reproduction may increase. Placement too close to the walls may,
however, also result in a bass boost which provides a reproduction that is undifferentiated and
lacking in details, depending on how close the loudspeakers are to the walls.
6. This effect is even more intense when the loudspeakers are placed in the corners of the room.
The broad increase in lower frequencies may rise to considerably more than six decibels. This
is normally not conducive to the sound reproduction and makes the bass tones become
dominant very quickly, while the midrange becomes diffuse and thick. All in all the music lacks
in detailed information. When placed in the corners of the room, the acoustic conditions mean
that the loudspeakers tend to perform significantly below their sound reproduction capabilities.
You can easily use your favorite music to determine the influence of the position of your
loudspeakers on their sound reproduction. Pieces of music involving a singing voice accompanied
by only a few natural instruments are particularly suitable for this test. Start by placing the
loudspeakers half a metre away from the walls and then move them around ten centimetres
closer to the wall in each listening test. As soon as voices sound start to sound diffuse and lose
their contours and the fine details fade away into the background or even completely disappear,
move the loudspeakers a few centimetres away from the wall again. Use the same prcedure to
find the ideal distances away from the side walls. By carrying out this test, you can quickly
determine the perfect position for your loudspeakers.

Bass Boost of + 3 bis + 6 dB
Bass boost of > 6 dB
Setup close to the wall: Low frequencies
are broadly reinforced by around +3 and
+6 decibels when the loudspeakers are
positioned close to the wall.
Setup in the corners of the room: Low tones
become significantly louder and overlap into
the midrange frequencies. This results in a
washed-out and lethargic sound reproduction.
