I have a rear projection crt tv. Right now, my center speaket is on top of the set, but I want to put the TV on a riser, maybe 18 inches higher. This would move the center speaker really high -- like over 6 ft high. So, do I keep it there and angle it down, or do I place it in front of the TV? If I put it in front, it will stick out a good 18 - 20 inches or so (its bass port is in the rear.) Which set up would be better (or less bad)?
