Hi Shadorne, Now I am with you! But I think the numbers and their implications are a bit exaggerated.
It looks to me you are using the Robinson Dadson cure as opposed to the Fletcher Munson. I see that at 80db the R-D curve is up 30db (not 40db) at 20hz while the F-M curve is only up 10db at 20hz. But even so with the R-D curve at 40db you are then looking at 50db up at 20hz, still not even close to the 60db that you mentioned to sound like rustling leaves.
I do think, now here we go, that the R-D curve is not as useful as the F-M curve. I believe the F-M curve to be the more accurate curve for our purposes. And yes thats good for me as now I do only have to be 10db up at 20hz as opposed to the 30db as suggested by R-D. Wow thats a big difference (20db). That is four times the difference between the two and the implications of power requiremens are huge. I will go with the F-M just because it is at least possibly obtainable by most audiophiles. And no I am not wimping out:)
