I was looking at the spreadsheet which only went down to 16 Hz. What am I supposed to do with the .cal file?

Most people around here use a software program called
REW. It is free and
downloadable. REW uses the .cal files.
But you can also modify the Excel file if you are inclined. The .cal file is a simple text file that can be read with Windows Notepad. The compensation values could be used in the excel file to extend it down to 10Hz. Using the same 1/6th octave spacing as the existing excel chart would add the 4 values below 16Hz(15.874) of :
14Hz(14.14) = -18.61 dB
13Hz(12.6) = -20.13 dB
11Hz(11.22) = -24.15 dB
10Hz(10.00) = -27.00 dB
I would recommend taking a look at REW...
