When calibrating my sub I noticed that the 1070's internal sub test tone runs about 10 db hot. So when I first calibrated using the 1070 internal test tones matching speaker levels with sub level I would get very lttle base when actually playing a movie. I then calibrated the speakers with the sub using AVIA and got things sounding the way they should in the bass department. I went back and ran the 1070's internal sub tone and sure enough it was at least 10 db hot compared to the speaker levels.

As a side note, I have an SVS pb12/plus sub and one of my test movies I use is the crash scene in Flight of the Phoenix. I measured 109 Db on my SPL, the whole house was shaking. That was way too loud!
