Problems during sound leveling my receiver

[ridergroov1]

Hi there. I recently got a new subwoofer so I setup all my levels for all my speakers and with this new sub I started the volume knob on the sub at about 65% but when adjusting the levels I have to have my receiver sub level down at about .75 to get it level so I dropped the sub volume knob down to 50% and was able to get the receiver level to the sub to about 1.25. For levels my receiver has 10 bars and adjusts in increments of 1/4 of those bars so when I say .75 for the level I'm not even past the 1st bar out of 10. It just seems bad to have the receiver outputting so low for something. Thoughts? I hope that wasn't confusing.
