Sonodyne Avant S1 - Manual (Page 5)

Finding the right position for the Avant 150s is also very important. The
following should aid in locating that optimal position while using them as
front speakers:
· Ensure that there are no objects between the speaker and the listener.
In general, placing a loudspeaker near a rear and/or side wall will
boost the low frequency level but at the same time create reflections in
the midrange and treble area, which results in a deterioration of the
stereo perspective. Therefore, it is not possible to recommend one
single perfect placement in relation to the rear wall, as the optimum
distance will depend very much on the acoustics of the listening room.
As a guideline, the optimum placing will be about 30 to 60 cm from
the rear wall. The distance to the side wall should be at least 50 - 80
cm.
· The distance between the 150s should be the same as the distance
from either loudspeaker (left and right) to your preferred listening
position (thus forming an equilateral triangle with the left, right
speakers, and you as the three vertices.) If distances are not a
premium, then the optimal position could be attained by playing a
stereo recording, separating the 1501 still an acoustical (hole) is
formed in the middle. Then bring the two 150s together to attain a
uniform sound front.
· The 150s should be angled slightly toward the listening position, to
adjust the higher frequencies (treble response) level to suit the room
acoustics and your taste. This will also ensure that the optimum
listening position becomes less critical.
· The 150s should also be placed on either a solid bookshelf or a floor
stand to raise the center point of the loudspeaker's front baffle position
(mid position between the woofer's center and the tweeter's center) to
the actual ear level, which for a person of average height is about 1m
from the floor.
· The Avant 150 is also excellent at reproducing discrete surround sound
information. To do so:
- Place the speakers on the wall using a customised shelf, or using
the Sonodyne AV150(SW) wall mount or AV150(FS) floor mount
brackets.
- Tilt the speakers so that they aim at the listening area.
- The 150 may be placed on the rear or side walls. Ideally, the
distance between the speakers and the seating area extremity
should not exceed 2m. However, since rooms are different, we
recommend that you experiment for best results
