I think you misunderstood my question. What I'm asking is how loud the REW tone signal is (from the single frequency tone generator), when played through an audyssey calibrated receiver. All receivers should play the signal at the same volume if it is properly calibrated with audyssey. I'm asking how loud the 0 dB tone generated by REW is, basically what is the "reference" level of a generated tone from REW?
To reword it:
Assume audyssey calibrated receiver, and an absolutely perfectly flat FR curve from 0 hz to 20 khz.
If I play a 25 hz tone, or any single frequency, from REW, at a level of 0 dB, what will the measured SPL be at my listening position, if the receiver is set to 0 dB?
