Adjusted 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). Adjusted
mid frequencies response may be preferred when the speakers are insta!led 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. Decreasing high and mid frequencies increases relative bass response, while

To modify the response, simply flip the baffle-mounted switch or switches to the alternate
position—upper, white dot in is the normal position; lower in is the decreased position.
These heavy-duty switches are designed to handle the currents of high level sound
without compromise.

C. Listening—Balance, Range, and Imaging
Our goal is to provide listeners with completely convincing, "being there" performance. In-
wall installations place greater physical limits on systems than freestanding box systems.
However, their performance, particularly considering the physical limits and the resulting
minimal intrusion into the listening space, can be startling.

Final judgments on the quality of the sound output are of course personal. We encourage
listening to the speakers with clear and familiar recordings—particularly of female and
male voices and acoustic instruments—to convince and satisfy listeners of the natural
tonal balance, wide frequency and dynamic range, and spatial imaging delivered.

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, if significant, void
their warranty. If a removable Baffle with drivers will be installed later, the construction
dust and paint shield should be installed after the Finish Frame is installed to close the
opening and avoid any excess drywall compound, plaster, or paint on the unexposed
sections of the Finish Frame.

B. Painting Finish Frames
The Finish Frame is made of ABS plastic 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 aluminum 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

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 Finish Frame.

A. Swivel Tweeter
Additionally, when used as a surround
speaker, you may prefer to aim the tweeter away from the ears of listeners to provide
more diffuse, less direct sound. A small pivot of the tweeter with listeners nearby, is the
equivalent of turning a cabinet speaker slightly.

In either case, carefully pivot the swivel tweeter to aim it towards or away from primary
listeners.

Be careful to touch only the plastic perimeter —do not touch the aluminum
dome or the plastic phase vane and protector directly in front of the dome. Denting
the aluminum dome causes irreparable damage not covered by warranty.

n-wall systems are balanced in design for as much bass as possible. Bass is a difficult
commodity to deliver in the desired quantity in the limited cavities of in-wall installations.
Increasing bass response is effectively decreasing high and mid frequencies response

The CW160R and CW160S use a unique pivoting SonicGuide™ tweeter. An issue with
post mounted coaxial tweeters is that, even the best tweeters, have their response
degraded by poor baffling and reflections from the woofer behind them. The SonicGuide
is a constant directivity waveguide that greatly improves response smoothness by
preventing the sound from radiating backward to the woofer cone. Additionally the
SonicGuide can be pivoted and turned to direct the treble energy towards the listeners
much as you would angle-in a pair of conventional loudspeakers. The final result is the
smoothest possible sound at the listeners position.
