Center and Sub Calibration question

[Doc Adams]

We obtained a calibrated analog sound meter and used the Avia DVD to set up our 5.1 speaker system. We set all speakers to be 75 db at the listening position, except the sub. Try as we might we could only get about 55 db from the sub. Some folks on this board say that the sub should even be 5 or 6 db higher than the others. That is well out of the question for us. Does this mean that our sub is underpowered, too small, whatever? This all sounds like too much sub for us anyway. Any ideas? Thanks.

Also, when watching DVDs the center channel seems too meek. Does anyone else boost the center cahnnell above recomended levels?
