Center Speaker

Most movie dialogue is a discrete multi-channel format that will come from the center speaker, so careful positioning is an important part of a good home theater system. Your eyes and ears should focus your attention towards the center of the screen.

The center speaker can sit on top or directly underneath the TV, as long as it is located on the center line and not off to one side. Ideally, you would try to maintain a deviation from the center line of the speakers of less than 12”. This means the center speaker will not be lower or higher than 12” to the center measurement of the LEFT and RIGHT MAIN speaker center measurements.

Position the front face of the speaker close to the front edge of the TV cabinet. (The sound waves may otherwise reflect off the top of the TV cabinet and distort the center imaging). Some systems use two center speakers, one on either side of the TV. As they are in mono, the result is a sound image that is positioned exactly at the screen center. This is an acceptable approach where the room is wider and the LEFT/RIGHT speakers are further out.

Tweeter position: To get the most out of your system, Emotiva recommends that you position your center channel speaker with the tweeter facing down (towards the floor) when the speaker is mounted above your TV, and facing up (towards the ceiling) when the speaker is placed beneath the TV.

Note: Speakers are not magnetically shielded and many subwoofers are also not magnetically shielded and thus may distort a CRT television if placed too close. If you want to check if this will be a problem, select an unused video input on the television to bring up a single color screen. If you see any color distortion anywhere on the screen, an unshielded speaker is too close to the screen and should be moved away from the television until the color distortion disappears. Please note that all modern LCD, DLP and Plasma televisions are not affected.

Side-Axis Speakers

Some preamplifier processors feature side-axis channels which are matrixed and derived from the left and right front channels, so they are available in stereo as well as surround modes. If available as a feature, the processor should have a set-up menu to turn the SIDE-AXIS channels ON or OFF. Many Emotiva processors have this feature.

Typical placement of side-axis speakers is depicted by the speakers that appear to be "suspended" where walls are in the room. Wherever you position them, place these speakers along the side walls, close to the fronts. You can also angle them in towards your listening position for better results. Using a specific surround speaker (such as the ERD-1) for side axis speakers is especially beneficial because you can configure the speaker to be a dipole or bi-pole configuration depending on its location. Try a dipole configuration initially to see how you like it.
