The SCM50/ SCM100 used the old model Vifa Ferrofluid-cooled Soft dome 25mm (one inch) tweeter, which i presume made to order per ATC specification, unkown type/ model - probably similar to D25-TG-05-07. That was before 1997/8??.

The newer model, especially SCM50 SL PT / SCM100 SL PT 3-way passive monitor floor standing system uses Seas Excel either T25C-003 (E036) or T25FC-001 (E006) and for sure not a Millenium T25C-002 (E011).

See below information that I recently found ATC catalog/ brochure on Japaneese

I am pretty sure for this. See the picture of the tweeter.
