Hi, I have been having problems with my center speaker. The Audio is very quite/muffled when there is lots going on in a movie. For example in the Pod Race seen in Star Wars Episode 1 you can't hear the two headed commentators and some other audio during the race. You can hear them speaking but you cant make out what they are saying. I think the problem is due to my center speaker having a lower sensitivity rating than my fronts. I have tried changing the settings on my amp but it doesnt seem to make much diffrence. My center speaker is the Mission 77c with a sensitivity rating of 85db. My Fronts are Mission 774 with a sensitivity rating of 89db. Is this 4db diffrence likely to be causing the problem? I am thinking of changing my center to the Mission M5c with a sensitivity rating of 87db. Is this wise or do I need to find a center speaker that has a sensitivity rating closer to 89db? My system is as follows: Center - Mission 77c Fronts - Mission 774 Rears - Mission 771e Receiver - Sony DB930 Help would very much be appreciated.
