I already knew that the response curves of the B&W's were relatively flat. That's what they use in most of the recording studios for classical recordings back in the time frame when I bought them. I went through a phase where I was listening to a fair amount of classical recordings and on the liner notes, they mentioned B&W monitors. Wilson at that time was relatively new, I almost bought them, but I got the B&W's instead and I guess as a courtesy they included the response curves to show that they were closely matched, which was a nice touch, so they showed what I already knew. But, I read various magazine articles and at the time, the reviewers were mentioning how flat of a response they were, but this was many years ago and in the beginning of my getting more involved with the learning process. I would have LOVED it if the cable mfg had response curves, it probably would have helped me greatly in the learning process. I used to read the spec listings when I was a kid reading the buyer's guides of equipment trying to make sense. So, that's when I learned about slew rate, damping, distortion levels, etc. etc. etc. It's all part of the process of learning about this stuff.
What surprises me is that there are a people that seem to not want to see response curves. That floors me. To me, people that are into this stuff should be all over this sort of information. In the crowd that gets involved with studio equipment, they read specs, they like looking at any measurements they can get their hands on. That's what surprises me about your comments. I would think you would want as much information as you could before making a purchase. I don't just walk into a store asking for the most expensive item, whether I can afford it or not. I only buy what I feel comfortable. If I can get good audio and pay less, I'm up for that. I look at the big budget products to get a sense of what it can sound like and try to get the best sound for whatever budget I'm working on and specs and measurements help me in my selection process.
