Illuminati (2nd Degree)

Took some SPL readings at 1 meter between the speakers with the Stereophile test CD with the meter set at "C" weighting 'slow', 80dB.

Using the corrections on the Audiogon board by Sean:

1k 75dB
200 77
160 79.5
125 81.5
100 84
80 83.5
63 79.5
50 77.5
40 76.5
25 75

Ambient noise level seems to be about 50dB. The increase between 80 and 125 Hz is at a point a little higher in the spectrum than I would have thought. +9dB at 100 Hz is a little odd? Room is 15x28x8 with lots of stuff in it.

Does any of this mean anything?
