    Over the past few days I've been slowly calibrating, tweaking and just plain playing around with my new SVS PC-Ultra.

    My question is this:

    Are the correction factors for the Radio Shack unit applicable to other brands' models, or should I go by the values that I'm getting on my SPL meter? (FWIW, I'm using an Extech Model No. 407727)

    For more info, see: extech.com/instrument/products/400_450/407727.html

    Thanks.

    If you have $40, get the meter calibrated against a known standard and generate custom correction factors. After that, WYSIWYG.

    The CFs for the RS meter are a combination of the theoretical c-weighted CFs, and some additional error introduced by the meter itself.

    At a minimum, if your meter is c-weighted, use the CFs for that curve. Anything beyond that is a guess, really.

    You could try contacting the manufacturer.
