WDXRS Supertweeters

[VantheMan]

Did anyone ever make these ? I rather fancy giving them a shot because I´m bored and these would seem to be within my reach, skill-wise. I have the WD25TExs and was wondering if their supposedly rather special in its day Millennium tweeter might preclude the use of such a supertweeter. I remember that Peter mentioned their use with the WD20s because of them being a co-axial design which might need a bit of a push in the upper frequencies and even then I seem to remember him saying some will love them, others won´t.
I guess I just need a shove to get my finger out because I use external crossovers, placed close to my amp and so will have to change my 4-core cable to 6 core . Might get a bit complicated.
