Ok, I turned up the following frequency's.

125hz by 3db
500hz by 3db
1000hz by 3 db
2000hz by 3db

I turned up the 125hz frequency because you said the human voice frequency is between 100-200htz. I figured this would help also. Is this the wrong thing to do? Thanks

I also turned down the overall volume of the center to match the to M60's DB level.

I will let you know how it works out tonight while Im watching TV.
