Audio meters are not, usually, accurate at very low frequencies. I will asume you are using the RS meter. There have been many compensation tables published and many debates about it, so I can't guarantee these numbers (Latest I could find) are 100% accurate, but they will be very close.
At the specified frequency you add the dB figures to the reading of your RS meter:
10 Hz +5 dB
12 Hz +6 dB
16 Hz +14.8 dB
25 Hz +7.8 dB
30 Hz +5 dB
40 Hz +3.2 dB
50 Hz +2 dB
80 Hz +1 dB
100 Hz +1.2 dB
On the other issue. Have you bottomed out the SVS? If not, on what do you base the maximum SPL number (109dB) for the SVS?
Regarding speaker break in. There are those who believe and those that don't.
There were test performed on this claim, it covered both objective (measurements) and subjective (listening) testing. The tests were performed double blind. First several model speakers (in pairs) were tested and measured. Then one of each was put aside while the others were subjected to heavy use. (If I remember correctly both white noise and music was used)
After the "break in period" speakers were tested and listened to again. The differences between the :broken in" and not were....
Less than the difference between two new speakers.
Listeners could not tell the differences between the broken in and not speakers.
There's yet to be a double blind test that shows differently.
One most make its own conclusion.
