Fernando- Easiest way to match the center speaker to the main L and R speakers is to ditch the center speaker altogether and use the "phantom" center channel mode in your processor or receiver. No problems with "height" match, no problems with "tonal" match, etc., etc.. And viewers sitting off to the sides will have the sound "anchored" to the screen if your mains are half-way decent at imaging.
Placement of Center Channel Speaker
What is considered good practice with regards to placement of the center channel speaker relative to the front main speakers in a home theater set-up? Specifically, is it acceptable to have the center channel higher (sitting on top of a TV, ~58" off the floor) than the main speakers? I was thinking of angling the center channel downward towards the listening position.
Thanks,
Fernando
