My church lowned me there Radio Shack Digital SPL meter today. I set it up about two feet off the floor on the edge of a table about two foot from where I sit. I have my receiver hooked up to my computer so I used the winISD signal generator. I did test tones from 12 Hz to 90 Hz. here are my results.

80--------63

84--------64
86--------64
88--------64
90--------64
I thought the readings would be all over the place but they seem really flat, did I do something wrong? By the way the SPL meter was set to c weighting and fast response. The sub is a 230 L sealed tempest. The meter was 7 ft. away from the sub and I sit about 9 ft away from it.
