ACOUSTIC TREATMENT MATERIALS

As previously mentioned, the Salon2/Studio2 Loudspeakers
utilize high-order networks which optimize both the on-axis and
off-axis response. Their optimized response minimizes sonic
degradation that can 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 points 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 has 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 boundaries, 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.

COMBINATION SPIKES/GLIDES

When shipped, combination spikes/glides, shown in the next
page in Figure 6 and 7, are not attached to the bottom of the
cabinet. For optimal stability and to accommodate installations
on tile, hardwood, and carpeted floors, you can install the
combination spikes/glides. Use the glide side to protect tile and
hardwood floors.
Caution
When moving the Salon or Studio2, avoid dragging it across
the floor. If the Salon2 or Studio2 are placed on a carpeted
floor, the spikes/glides should be adjusted with the sharp end
protruding from the cabinet.
The spikes/glides should be used so that the smooth
"glide" end is exposed to protect tile, hardwood floors and
furniture.
To install the combination spikes/glides:
1. Place the speaker on its side on a soft towel or carpeted floor.
2. Select the appropriate end of the spike/glide, depending on
your surface. If the speaker is to be used on a hardwood floor
or smooth surface, use the glide end of the spike.
3. Locate the four threaded insets on the bottom of the speaker.
4. Screw the first spike into the threaded insert, making sure to
include the locking ring and felt washer in the order shown.
5. Repeat step 4 for the remaining three spikes. Make sure all
spikes are evenly threaded to achieve a level balance.
