PRODUCT DESCRIPTION The AMC650r and AMC680r in-wall loudspeakers deliver outstanding performance. They incorporate a unique waveguide tweeter that has a large mounting area to extend its response. This allows a lower crossover point which produces a more integrated sound. The painstakingly developed shape and profile of this waveguide guarantees much smoother and wider response than with post or “eye socket” mounted tweeters. In addition the tweeter is mounted on a 20- degree angle which provid

STEREO IMAGE The distance between the speakers determines the width of the stereo image. If the speakers are placed too close together, the image will be too narrow; too far apart and the blend will suffer, creating a “hole in the middle.” We recommend an angular separation between 45 degrees and 60 degrees (when viewed from above). This is equivalent to a 45° separation between the speaker systems that is about 75% to 100% of the distance from 60° the listener to either of the speakers. Creatin

Using As a Surround Speaker The compact size and neutral tonal quality of the AMC650r and AMC680r make them perfect for the surround channel speakers of a home theater system. Place the speakers toward the back of the room, to the sides of, or behind the listening position. An indirect sound path from the speakers to the listening position results in a more diffuse and convincing surround sound effect. This can be achieved by taking advantage of the angled waveguide tweeter. Orient (rotate) the

INSTALLATION Note: The speakers should be mounted on a flat surface to form a good seal between the speaker flange and the mounting surface. 5 Wall or Ceiling Material 1. Make a 7 ⁄8-inch (194mm) cutout using the supplied template. It is not necessary to remove fiberglass insulation that may be behind the wall. 2. Run wire from amplifier to cutout. Allow an extra foot of wire at the cutout. 3. Remove the speaker grille. Carefully pry up one side with an awl or small screwdriver. The AMC650r and

LISTENING LEVELS AND POWER HANDLING The power recommendation for the system assumes you will operate the amplifier in a way that will not produce distortion. All speakers can be damaged by a modest amplifier that is producing distortion. If you hear a gritty noise or other signs of strain, turn down the volume. Prolonged or repeated operation of your speakers with a distorted signal can cause damage that is not covered by the warranty. When turning on the system from a remote location, it is har
