    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.
