I have read some different articles that have stated that the center channel speaker should be offset to the left of center slightly. Is this true? If so, how far off center? I am getting ready to place my speakers and would much appreciate it if I knew this info before I do.


Thanks,

The center would best be placed dead center. The dialog would be focused on the on screen better.Then place the mains accordingly. The alignment is the majority in this manner. The center should be placed at the same alignment, (or slightly recessed) from the mains. The center should be at the same height (preferred) if using a THX microperfed screen with your CRT PJ. Or for near-best cinematic sound place the center under the screen and aim it slightly upward. Place the mains on the same plane.

do you have links to any of those articles?

funny, Dennis Erskine, who knows a few things about sound in an HT suggests placement above the screen due to the fact that we don't localize sounds that are above us as much as those below us. I agree that the goal is to keep it as close to level with the mains as possible-- particularly the tweeter as this is more directional.

The center speaker should be placed slightly off-center of the width the room to prevent excitation of room modes. Six to eight inches to either the left or the right is sufficient. Russ Herschelman (sp?) has written numerous articles about proper placement of speakers and seating relative to each other and the room's dimensions in various home theater magazines. Given the importance of this issue it is ironic how few people set up their home theaters correctly.

In the unlikely event of the center channel (not the subwoofer) creating a problematic low frequency resonance, moving it six to eight inches wouldn't be enough I'm afraid. You'd have to move it more to one side, which would mess up the symmetry of your front sound stage. The dialog wouldn't appear to come from the right place, among other problems.


If your center speaker actually did succeed in exciting a widthwise resonant mode, it would likely be fairly high - over 100 Hz. This is best controlled through wide-band absorption, which a home theater probably needs anyway to maintain uniformly low reverberation across all frequencies.
