Perhaps you can 'enlighten' us as to the particular SF model you heard. BTW, looking at the cone material on SF's is not going to really tell you how they sound. Unless you believe that a silk dome sounds "soft"!! FYI, there are any number of ways to make just about any type of speaker sound "laid back"....change the front end gear feeding it and you can do this with little problem.
I didn't even ask, because I didn't really care. I wasn't there to buy them. There was actually 2 different sets. A small monitor, and a tower that looks a lot like these. And yes the cone material does matter when it comes to how something will sound. If you had a clue about drivers you would know this. You're obviously arguing for the sake of argument. I can't even compliment something without being attacked.
