Clear, clean center channel

[Richard in SF]

My room, like many is a sonic nightmare. I have older, hugh Def Techs which give a good "theater experience", but center dialog is "muddy". I have tried horizontal and verticle, tilt and no tilt. I am thinking of taking a blind swing at a used HTM or CDM. Comments?
Thanx,

Any problems could very well be the room and location. Got a picture of your centre speaker showing it's location and objects nearby?
