OK I am going to pull my hair out My setup: Onkyo 602 Fronts paradigm atoms Center CC-170 Rears Design acoustics Sub STF-2 Now I know the fronts and rear don't match but I can't replace them right now besides they look the same and sound very close. After I do auto setup on my onkyo the sound is pretty good. After I try using a SPL meter with Sound and vision DVD the sound seems lower and also the bass. With auto setup my levels are : Left +4db center +3db right +2 db SR -1 SB -2 SL +1 Sub -1 (the sub volume is about half way) With SPL and Sound and vision DVD All levels are negative db and my ref level is about 13db (I left the sub level at 0 and adjusted the volume on the sub itself) After both setups I tested with music and movies (star wars II asteroid seen) With the auto setup I feel the bass and volume is about 25db. With SPL the I could not feel the bass ans I had to put the volume about 12db. What am I doing wrong? If I just leave the auto setup levels what volume should I put the sub at?
