    Can someone please help me with this program (http://www.pvconsultants.com/audio/eq/peq.htm) - I took data from my sub and when I entered it into the spreadsheet the resulting plot went way above the +12 gain value on the y-axis. Even when I take 60dB out of every value I recorded I still can't get a completely visible plot. Is there an autoscale feature somewhere? 86dB is the loudest value I recorded, so it wasn't like I had my system cranked up. Any help on this would be great - I used this program about a year ago but didn't have this happen and I'm scratching my head now. Thanks.

    This is what I get:

    On the Measured response sheet have you selected 'RS Calibration' in the top drop-down?

    The scale on the left is Normalized but can be changed.
    Double click on one of the X-Axis numbers on the graph (a Format Axis box will pop up). Go to the Scale page and change it to something like Minimum -20, Maximum 20 and see if that works.
