yep, I don't disagree with any of the above.There are loads of issues with your view. First the measurements I posted are professional measurements. They are more than sufficient enough to understand these speakers. There is simply much more data concerning these speakers than most. More than enough to know with certainty their issues and that they are not a good value unless the finish is worth thousands to you. In many ways Amir's data is collected in a manner not too dissimilar from those above--it is just that the Klippel automates the microphone placement. What you can't compare are these measurements to the myriad amateur headphone measurements on the internet. You can, for instance, certainly compare Amir's headphone data to that of Sean Olive. More, headphone measurements are not as dependable as those for speakers. There is a high margin of error. Amir has stated this numerous times. You can't fully trust any of them, including Amir's. The measurement technology is not there yet. Part of Amir's project is to figure out the limits of what he considers the best measurement apparatus. This is why he relies on EQ for confirmation. Again, what I think you should do first is learn to understand who actually knows what they are talking about. That you seemingly came to the conclusion that you mentioned about these speakers shows that you are listening to a lot of bad reviewers. We're here to help in this regard. You are absolutely right that both of these measurements can be hard to understand. This seems deliberate on Stereophile's part. But if you have any specific questions about these measurements, just ask.
I think both the Special 25 and Special 40 are probably good speakers, but both have shortcomings shown in the measurements.
so I will probably keep looking for an upgrade from my current Contour S 1.4.
there are many good reviews of Heritage Special, but I haven't seen any measurements. or at least no measurements from reputable sources.
what's curious about that model is that nobody points out in their reviews that it's basically a modern version of Special 25. at least the recipe is the same - both have an Evidence woofer and a Confidence tweeter. Heritage Special just has newer versions of the drivers.
