Overview
CRW-3 loudspeaker
CRW-3C center loudspeaker
Ribbon CRW loudspeakers, you get the
same advantages: high output, small
size, high efciency, and years of trouble-
free operation.
Conclusion
The Cinema Ribbon CRW loudspeak-
ers are a no-compromise answer to the
age-old question of Form vs. Function.
Why not get both? Combine these speakers with the SubRosa In-wall subwoofer
for the ultimate in hidden high performance.
The Cinema Ribbon CRW-3 and the
CRW-3C are high performance loud-
speakers that are specically designed to
work with your at panel display. Sharing
technology with the rest of the Cinema
Ribbon line, years of research and
decades of experience have gone into
these amazing loudspeakers.
The ribbon - a legacy rened
The ribbon in this loudspeaker is a remarkable piece of engineering, because
it has the output capability, purity, and
low distortion of a large 6-foot-tall ribbon
- in fact, it is derived from Bob Carver’s
award-winning Amazing Loudspeaker
from the late 1970s! The sound from the
CRW-3 ribbon is deliberately focused
in the forward direction, with very little
sound going up or down - reducing reections off the ceiling and oor, that disturb
our sense of space and imaging. The
CRW-3C features an integrated “acoustic
lens,” that disperses the signal for center
channel applications.
The woofers - a legacy rened
Sunre created the category of small-
box, high-power subwoofers more than
a decade ago with the original True
Subwoofer. This design relies on highpressure, “High Back-emf” technology
that provides very high bass output from
a very small box. When migrating this
subwoofer technology to the midrange
and high frequencies on the Cinema
Installation overview
A template is supplied to help mark
the sheetrock for cutting. A paint shield
is also supplied to aid in painting the
loudspeakers.
An optional pre-construction bracket
is available that will help you install the
loudspeakers in rooms that are under
construction. Please contact Sunre to
order this bracket. (It comes with its own
installation guide.)
The CRW-3 may be mounted vertically
between wall studs, either side of your
big screen display.
The CRW-3C may be mounted horizontally, above or below your display. For
existing walls, the horizontal mounting
will involve cutting a vertical stud and
some extra framing.
The CRW-3C may also be used
vertically as left and right loudspeakers,
in which case, the acoustic lens can be
removed.
A system of six screw clamps secure
the loudspeaker rmly in place in the
sheetrock, once the opening has been
cut.

CRW-3 Rear Connectors CRW-3C Rear Connectors Bridge Clips
1. Ribbon Binding Posts
2. Woofer Binding Posts
The loudspeakers have two sets of
binding posts that are joined with
bridge clips (3) for normal operation.
If the bridging clips are left in place,
then you can connect your amplier
outputs to either positive/negative pair
of binding posts.
Always use high quality connections
and speaker wires, and make sure
there are no loose ttings or stray wire
strands. The spring connections accept
bare wire or pins.
Connect the positive speaker-level
output of your power amplier or
receiver to a positive (red) input of the
loudspeaker. Connect the negative
speaker-level output of your power am-
plier or receiver to a negative (black)
input of the loudspeaker.
Make sure that the positive and negative connections do not touch, or this
may damage your power amplier.
Tighten all four adjacent nuts to make
sure the bridge clips are making good
contact.
3. Bridge Clips
From the factory, the two positive
binding posts are electrically joined
together with a bridge clip, as are the
3
5 5
two negative posts. Leave these clips
in place, unless you intend to biwire or
biamp your loudspeakers.
If the bridge clips are removed, the
loudspeaker can be biwired or
biamped. The ribbon posts (1) are then
used for connection of speaker-level
power to the ribbon section. The woofer
posts (2) are for connection of speaker-
level power to the woofer section.
(See page 16 and 17 for biamp/biwire
details.)

4. Speaker Wire Channel
To ease installation, the speaker wiring
can be passed through these channels
to the binding posts.
5. Clamps
Once the loudspeaker is pressed into
an opening in the sheetrock, screws
on the front panel are turned to pull the
clamps out and down to press against
the sheetrock, and secure the loud-
speaker in place.
