Introduction Thank you for purchasing a Sunfire XT-Series Cinema Ribbon 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-2 loudspeaker 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 Ribbon CRW loudspeakers, you get the same advantages: high output, small size, high efficiency, and years of troublefree operation.
Features CRW-2C 1 2 3 1. Binding Posts Each loudspeaker has one pair of goldplated spring-loaded binding posts. Always use high quality connections and speaker wires, and make sure there are no loose fittings or stray wire strands. The spring connections accept bare wire or pins. Connect the positive speaker-level output of your power amplifier or receiver to a positive (red) input of the loudspeaker.

Ribbon The CRW-2C and CRW-2 use the same ribbon driver. 3 9. Lens (CRW-2C only) The CRW-2C uses an acoustic lens over the ribbon to optimize the performance as a center loudspeaker. 8 10. Grille The grille is attached to the main body with magnets. To remove the grille, gently pry it away from the corners. 5 11.
Loudspeaker Location Center line of display CRW-2 CRW-2 Display CRW-2C (above or below display) The CRW series loudspeakers are designed to be a perfect sound compliment to flat panel displays. The CRW-2C center loudspeaker can be mounted above or below the display, and the CRW-2 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 them 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. Walk around the room, standing in all the positions where you might be able to place the subwoofer.
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-2C The CRW-2C 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.
4. Carefully cut out the sheetrock around the marked lines, and remove any debris from the hole. Wiring The front channels of Sunfire's Theater Grand Amplifiers each have two pairs of outputs. In a normal system, use the voltage source. This example shows the speaker wiring connections for a right front speaker. On conventional amplifiers, use the standard positive and negative speaker-level outputs. MINIMUM SPEAKER LOAD IMPED 3.
6. It is a good idea to secure the wiring from vibration as much as possible. Do not have the weight of the cables hanging on the terminals. Fitting the loudspeaker 1. Press the loudspeaker into the sheetrock opening, and screw in the six clamp screws. As the screws turn clockwise, the clamps 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 16 1. The supplied Sunfire badge can now be pressed in place to match the orientation of your loudspeaker. The adhesive backing holds it in place 2. Add the magnetic grille to cover the woofers and ribbon. 3. Enjoy your new loudspeaker.
