Center channel placement

[davef]

Wanted to know can the Horizon center channel be placed too low? Right now mine would have to on a stand in front of the TV I only 20 inches from bottom of the screen to the floor.
Would this be to low that it would affect the sound (dialogue) coming from the speaker?

Thanks

All speaker placement, regardless of how low, how high or even at an ideal location will affect the sound. That said, 20" off the floor will be fine
