Perhaps you can provide either some math or a graphical representation on where you get 25 Hz in this latest example or how you arrived at 96 dB of attenuation in the previous example. Until you do, I contend that these numbers make no sense (at least to me and most likely to the OP); and as such are not helping. IME these numbers are the only obvious source of contradictory information in the discussion that isn't coming from the OP. Considering everything else you've said was extremely helpful, I'm perplexed by this aspect of your contribution.
