First, can we agree that series attenuation is not desired and can alter crossover behavior?

Please refer to this line by David:

I also do my due diligence and let me just say that my sensitivity measurements (taken with reference standard gear and using several different methods) do not correlate with what was reported from the listening session. I don't know the cause of this discrepancy but I certainly invite anyone to do the comparison in their own home. The difference in sensitivity is audible...
It seems as though there is a discrepency as to what is being measured. Dave's is measurements do not seem to correspond with Craig's measurements. Dave is also saying exactly what you are saying....get both and try yourself.
