Yes, within the range of error of your SPL meter. The low-frequency errors inherent in the Radio Shack meter are significant. There is a correction table available on the internet if your meter is a Rat Shack model.
As you're no doubt aware, there are very large variations in low-frequency information from one source to another, CDs, analog vinyl, Dolby Digital 5.1 broadcasts and the like. I'm always adjusting my subwoofer level according to the source, by ear, to compensate for the vagaries of the source mix.

Yeah, I believe Ian mentioned in one of his videos re: multiple subwoofer set-up that the meter doesn't read properly below 50HZ anyway and is that possibly the case with any Room Eq System? I have always understand as well that similar limitation applies to the human ear as that was the purpose of the older receiver's "loudness control" to boost bass response to compensate, especially at low volumes so, in the end, you have to adjust the sub to personal taste.
