OK, Romy, that EnABL stuff got my attention!
I can't recall all of the bad ideas borne of good research, but this EnABL thing sounds a little fishy, and certainly it sounds too good to be true, as existing in a simple and really useful form. Can it be just so?
Of course we've known for some time that we could alter the sound of various drivers by "doping" them, putting light foam stuff on them, etc., basically by messing with their mass, but also altering their skin effects and radiating patterns with this and that.
But how can this EnABL thing/stuff work on anything that's supposed to go high? I mean, how, for example, would it work on a ribbon or a 'stat panel, which driving surfaces certainly exhibit boundry effects, too? Surely the theoretical benefits have to be offset by the mere presence of something more on the radiating surface?
Obviously, I don't get it.
BTW, I am surprised that TAD, which siupposedly caters to "pros", would give bad info on efficiency, but I will be more surprised if you get a stock unit to work for the top of the top end on your otherwise "perfect" hi-fi speakers. Few "pro" speakers are drop-ins for hi-fi, in my experience. I understand that TAD drivers are used in an expensive version of a JBL Hartsfield redux, but then, I remember the Hartsfield as fairly colored to begin with.
