This.

I know they test nice and nothing is revealed in the FR/SPL. I know they sound amazing. But that's it in a nutshell, Forward Mids. I've thought about it a lot because I
WAS so impressed with the sound, and can't figure it out, yet. I'm hoping I get a chance to try again soon, if for no other reason than the understanding might help further my own desire to design a set of speakers for myself.
My current theory is that it is the cone material itself contributing to this "forwardness." Aluminum, if I'm correct? I'm not saying Aluminum is bad... my Mini Phils have Zaph Audio's 5" Aluminum Mid-Woofer and its a solid little driver which I have had no sensitivity to. It measures flat, too.
???
I just think, for me, I'm sensitive to something in that range, and the two KEFs I listened to that day brought it out.

I did not listen to the Blades, though the local shop has a pair. Like I said: Soon.
