For tedious reasons, I want to measure the outputs each of my five satellites , across the frequency range, for comparison purposes. Among the possible tools I have at hand are a Rat Shack analog SPL meter, two Stereophile Test Discs (#s 1 and 2), Avia and Sound&Vision test DVDs, an an analog volt/ohm meter. What is the msot practical way for me to set up this measurement (positioning of the meter wrt the speaker being measured, what calibration setting to use, etc). ? It needn't be 'anaechoic chamber' quality, I just want to get an idea of how well-matched my speakers are across the audible frequency range. From subjective listening I'm getting the impression that one of them may be intrinsically 'off' compared to the others (even though they're identical models) -- not due to room placement.
