Rerurn to Romy the Cat's Site

I picked recently a pair of S3 drivers. Not that I need them but it was good deal – perhaps someone in UK have demolished an old movie theater and a large school of S3 drivers with original diaphragms hit the maket recently. Also, I always meant to try them for my Fundamental Channel as I was interested to see if they would go lower then S2 drivers. The S2 have ceramic magnet, so HF transients shell be too dry with my tube electronics. Still, the Fundamental Channel do not work very high, so there is a remote possibility that I will be able to go away with S2 driver for this channel.

Now, what I wonder: is anybody having the internals drawing of S2 and S3 drivers. The reason I ask is because my S2 in Fundamental Channel is time-aligned and when I screw the S2 in there then the distance between the throat of the horn and driver cone might be different. I really do not want to do re-alignment (because multiple reasons) and I would like to make the alignment decision based upon the drawing of the driver with marked up distances. I do have this drawing for S2 driver but I do not have it for S3. If someone has the S3 mount template with exact distance between the mounting throat and the tip of the cone then post it or shoot me a direct email.
