I forgot to mention that the rives test cd has corrected tracks for the radio shack meter from 20Hz up to 20,000Hz if you want to see what your in room frequency response is. Those are tracks 32 to 62 on the cd. Yes you are taking only 30 measurements from 20 to 20,000 Hz, but they are accurate and will at least give you an idea of how much your room is causing problems.
