SPEAKER PLACEMENT

Positioning your loudspeakers properly is critical in order to achieve the sonic performance of a home theater. Please read the following section for guidance in correct and optimal placement.

LEFT AND RIGHT SPEAKERS: If you have purchased a Synthesis Array Module digital home theater system, then one of the configurations of the SAM1HF/SAM2LF modules will serve as your front left and right main speakers. Please see the Configuration and Connection diagrams in the “SAM1HF and SAM2LF Configuration and Assembly” section to correctly configure your main speakers.

Since the left and right speakers have been designed for maximum local- ization of sound, they should be placed with the center of the speakers at about the same height on screen as the actors would be, to aid in the illu- sion that the actors’ voices are coming directly from their on-screen images. Ideally, the speakers will be placed about 45 degrees apart from each other, viewed from the listening position, so that the distance between the speakers is the same as each speaker’s distance from the listener (see Figure 1).

CENTER CHANNEL SPEAKERS: Please see the Configuration and Connection diagrams in the “SAM1HF and SAM2LF Configuration and Assembly” section to correctly configure your center speaker. Regardless of the configuration you have chosen, it is important to place the horn array vertically during installation in order to take advantage of its sound- dispersion characteristics. If you mount it horizontally, it will not provide the correct dispersion pattern. If the speaker is being used with a perforated projection screen, it should be mounted behind the center of the screen (see Figure 2).

If a nonperforated projection screen, plasma display or other fixed video device is being used in the installation, then the recommended location is directly below (and as close as possible to) the video display (see Figure 3), although the inverse of this method will work also.
