I tried out the analogue spl meter on my Atlantic Technology T170 theater and applied the corrections from here and here's what I got:

Hz dB
20 73.5
25 71
31.5 71.5
40 75.5
50 82.5
63 80
80 80.5
100 82
125 78.5
160 82.5
208 75.5 (used corrections for 200hz)
250 81.5
500 76.5
1000 78

I guess it's ok results with a 7 dB range from 40hz on up, but I was wondering if there were any other more corrections for any other frequencies. I particularly worried because my tests registered that 75-78hz is 7-14dB softer than the 80hz posted above, without corrections. I'd like to have some more corrections for frequencies in between the ones I have above to get a clearer picture.
