ACOUSTIC TREATMENT MATERIALS
The Voice2 features high-order filters at 235 Hz and 2 kHz that
optimize the loudspeaker on-axis and off-axis response,
minimizing degradations that occur in overly “live” rooms.
Placing minimal acoustic treatment materials at primary
reflection points will reduce these distortions even further. Ideally,
acoustic absorbers should be placed at the first reflection points
on the front and side walls and either acoustic absorbers or
diffusers should be placed at the first reflection point on the rear
wall.
Because the listener’s eyes and ears are on the same plane, the
“mirror method” is an accurate determinant of critical reflection
points. This method can be used to determine reflection points for
side walls, rear walls, front walls, and even the ceiling. Applying
acoustic treatment materials to the side walls is most important,
followed by the front wall, rear wall, and ceiling.
To determine reflection points using the mirror method:
1. Once the loudspeakers have been placed, sit in the primary
listening position and ask another person to slide a mirror
along the listening room walls.
2. Note the locations at which the person sitting in the primary
listening position can see either the left, center or right front
loudspeakers. Be sure to look for all of the speakers in the
reflection on each room boundary, including the front and
rear walls. These are reflection points that require acoustic
treatment materials.
If acoustic treatment materials are not available, hanging a rug
over the reflection points will help reduce degradation in overly
“live” rooms. Carpeting the floor between the loudspeakers and
the primary listening position and placing irregular surfaces such
as bookcases at first reflection points will also help minimize
strong reflections. Avoid placing large reflective surfaces such as
coffee tables between the loudspeakers and the listeners for
critical listening.
VOICE2 CRADLE
The Voice2 Loudspeaker includes a “cradle” assembly that
provides solid footing, while providing adjustable tilt to optimize
the speaker position whether it is placed above or below a video
image. The included cradle assembly is suitable for use when the
speaker is to be placed on a shelf, on top of a large rear projection
video display, or in appropriate custom installations. To adjust
the Voice2 , loosen the adjustment knobs located underneath the
cradle. When the loudspeaker has been appropriately positioned,
firmly tighten the tilt adjustment knobs to lock the Voice2 in
place. Do NOT over-tighten
An optional pedestal is available for placement on the floor,
such as in front of projection applications. See Appendix A for
pedestal unpacking installation instructions.
