XI. PAINTING
A. Construction Dust and Paint Shield
The Construction Dust and Paint Shield should be installed when the speaker
drivers are installed, if construction is not yet completed. The shield fits snugly to
protect the drivers. It can be removed after painting and other construction is
completed by squeezing the finger holds in the shield and pulling the shield out
from the frame. Construction dust or paint on the speaker drivers will negatively
affect their performance and warranty. Damages due to improper painting will not
be covered under warranty.
B. Painting Finish Frames
The Finish Frame is made of aluminum and can be painted following standard
practices and techniques. Be sure the frame is clean and dry, free of any mold
release agent residue and of any construction dust. Lightly and evenly scuff with
extra fine sandpaper, rounding square edges slightly, to ensure good paint
adhesion. Apply two to three coats, thinned slightly with a paint conditioner, to
produce an even surface. Imperfections can be sanded between coats. Spraying
will yield best results.
C. Painting Grilles
The Grille is made of painted metal and can be painted following standard
practices and techniques. Apply two or three coats of paint, thinned well with a
paint conditioner to avoid blocking Grille perforations while increasing paint
coverage of the sides of the holes. Spraying will yield best results. A roller tends
to deposit too much paint, blocking holes. While the paint is wet, blocked holes
can be cleared individually with a paper clip, or small nail (#18 wire brad is the
closest size). Some excess paint can be removed using a dry brush to pick-up
the excess paint and then brushing it out on a scrap of paper or rag and
repeating the process. It may be preferable to wipe the wet paint off with thinner
or a rag and begin painting more carefully again. With a contrasting color it is
important to paint the sides of the perforation holes to show consistent color off
axis. This is best done by spraying or brushing carefully from several angles side
to side and up and down. Allow a painted Grille to dry thoroughly before carefully
installing it in the frame.
XII. SETUP
A. High and Mid Frequencies Switches
We at PSB have spent great effort to make the frequency response of your in-
wall system as flat and neutral as possible. Still, variations in the listening
position, room acoustics and listener preferences can be well accommodated
using a few chosen controls.
Adjustment to high frequencies response may be desirable when the speakers
are installed in locations surrounded by hard surfaces that reflect the sound
output with very little absorption, causing a "hardness" to the sound (and/or with
some electronics). Adjustment to mid frequencies response may be preferred
when the speakers are installed close to adjacent walls which can emphasize
some upper bass frequencies (and/ or with some electronics). Decreasing mid
frequencies is generally desirable to smooth the crossover transition and avoid
an upper bass "hump" in systems where bass is supplemented by a subwoofer.
