I'm new to surround sound so...bear with me please. I have an Onkyo HT-R391 receiver that came with 5 speakers and a subwoofer. I'm having trouble adjusting the center and front left/right speakers. The sound is a lot better than tv or stereo speakers, but I think I'm not setting it up properly. First off, I hear about 50% more out of my right side than my left side. I believe that I've found the right balance between the speakers, though. The speakers go from -12db to +12db. What should I set the center speaker at so that I can clearly hear the dialogue but not get overwhelmed by the effects ? Right now, I have the left front speaker set at -2db, the right front speaker is set at -8db, and the center speaker is set at +12db. But I still find that the effects are a tad too loud when I have the volume where I can clearly hear the dialogue. I guess it all depends on the way they mix a particular movie, right ? Would setting the front speakers to their lowest levels (right front at it's lowest of -12db and the left front speaker at -6db) help any ? Also, how loud should I set the left and right surround speakers ? Should they be set at the same db level as the front speakers ?
