Introduction Thank you for purchasing a Sunfire XT-Series Cinema Ribbon CRW in-wall loudspeaker. We hope you enjoy it and the music it makes as much as we have enjoyed creating it for you. As an exclusive XT-Series product, this loudspeaker follows a great heritage of both world-class ribbon loudspeaker designs and industry-leading subwoofer technologies.
Overview CRW-3 loudspeaker Ribbon CRW loudspeakers, you get the same advantages: high output, small size, high efficiency, and years of troublefree operation. Conclusion CRW-3C center loudspeaker The Cinema Ribbon CRW-3 and the CRW-3C are high performance loudspeakers that are specifically designed to work with your flat 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.
Rear Panel Features 1 2 3 CRW-3 Rear Connectors 1 3 2 CRW-3C Rear Connectors 1. Ribbon Binding Posts 5 4 5 3 Bridge Clips 5 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 amplifier outputs to either positive/negative pair of binding posts.
Front Panel Features 6 8 9 10 7 11 6. End Caps These decorative end caps can be painted to match your room decor. A paint shield (13) is supplied to cover the drivers during painting. 7. Ribbon Adjustment This allows you to adjust the level of the ribbon section relative to the other drivers. The range of adjustment is ± 3 dB, and the default setting is in the middle (0 dB). Perform a listening test and adjust as desired. 8. Woofers The CRW-3C uses four identical custom drivers.
Loudspeaker Location Center line of display Display CRW-3 CRW-3 CRW-3C (above or below display) The CRW series loudspeakers are designed to be a perfect sound compliment to flat panel displays. The CRW-3C center loudspeaker can be mounted above or below the display, and the CRW-3 can be mounted at either side. The following details show various systems incorporating the loudspeakers, with a subwoofer to handle the low frequency range.
If you have a Sunfire or Carver system equipped with Sonic Holography, then it is recommended that you use a tape measure to set the left and right loudspeakers to be an equal distance away from your listening position, within half an inch tolerance. (Sonic Holography is a unique process designed by Bob Carver to enhance the three-dimensional effects and realism of stereo sound.) 5.
With two surround back loudspeakers, set the surround back loudspeakers behind and between the surround loudspeakers. Subwoofer Location The best location for a single subwoofer can be found by following these steps: 1. Place the subwoofer on your couch or favorite easy-listening chair. 2. You can then either run a calibration (noise) signal through it, or play some of your favorite music samples with heavy bass. 3.
Using a subwoofer The Cinema Ribbon CRW loudspeakers are designed to be used with a subwoofer to fill in the lower frequency range. They are not designed to accept 400 watts of power at the full frequency range. Your system should be designed so that the Cinema Ribbon CRW loudspeakers receive only the range above 80 Hz, with a subwoofer to handle the frequencies below 80 Hz.
continued.. you do not have a subwoofer connected, you will be missing the 5.1 LFE (low frequency effects) information. NOTE: If your processor or preamplifier does not have a crossover control, you might need an external active crossover to split the audio signal into a low-pass range for the subwoofer, and a high-pass range for the Cinema Ribbon CRW loudspeakers.
Installation Read the details on page 8 to help determine the best position for your loudspeakers. CRW-3C The CRW-3C center loudspeaker can be fitted horizontally, either above or below the display. A pair can also be used as left/right speakers if the acoustic lenses are removed. This is done by gently prying them off at the four corners. Preliminary steps: • If the TV display is in place, it should be removed from the wall. • Clear the area where you are going to work, so it will be safe.
Wiring In normal wiring, the bridging clips (item 3, on page 6) are left in place, so the ribbon and the woofers are powered by the same amplifier channel. 3. The front channels of Sunfire's Theater Grand Amplifiers each have two pairs of outputs. In a normal system, use the voltage source. See page 16 for other wiring options, including biamping, or biwiring. MINIMUM SPEAKER LOAD IMPED 2. 14 Connecting the wires 4.
Fitting the loudspeaker 1. Press the loudspeaker into the sheetrock opening, and screw in the six clamp screws. As the screw turns clockwise, a clamp rotates out and presses onto the back of the sheetrock to hold the loudspeaker firmly in place. Painting the loudspeaker 1. Press the paint shield in place to cover the woofers and ribbon during painting. 2. Remove the paint shield when the painting is done. Final steps 1.
Biwiring In a biwired system, each loudspeaker is driven by one amplifier channel, but separate speaker wire pairs are used for the woofer and ribbon connections. Make sure the bridge clips between the woofer and ribbon posts are removed from the loudspeakers when you want to biamp or biwire them. If not, this may cause damage to the amplifier.
Biamping The loudspeakers have two sets of binding posts that can be used for biwiring or biamping. These posts are joined with bridge clips for normal operation. • Connect the amplifier’s right back output to the right loudspeaker’s woofer input terminals. Connect the amplifier’s right front current source output to the ribbon input terminals. Make sure the bridge clips are removed from the loudspeakers when you want to biamp or biwire them. If not, this may cause damage to your amplifier.
