Again, Tbg, you don't get it. Why set up the strawman about "perfect speakers"? Did I say that? Uh, no.
But there is great consistency among good designers about a great many things that matter. They all do it differently, weigh things differently, and have their own sensibilities. A balance of tradeoffs.
Remember, you were the one that said "I have known many speaker manufacturers over my time in audio. Measurements have not been a major consideration in any case that I know of."
I simply proved that this was an ignorant statement. But you can't admit you're wrong, when clearly you are.
I'm done with this thread and you, Tbg.
