Tim something seems odd in that photo, when I took off the faceplate there was still an 1/8" ridge around the surround. You can see it there but it is flush with the rest of the plastic not raised. I assumed it was part of the plastic but maybe it was removable?
Well I'll be, there is a separate plate for the phase shield. This will get the waveguide throat from 1.61" at the grill down to 1.49" at the surround with the PS plate removed:
Interesting, and much easier to produce a simple interface to the guide. 1.49" isn't so much over the 1.475" that worked for the RS28F, perhaps someone will test both in the same guides. It's also good that should an RS28 fail, it can be replaced without too much modification to an existing waveguide, provided the guide is used with the original faceplate and mesh plate removed.
I do like the large alignment pins that locate the diaphragm. They're a needed improvement over the RS28.
This is good news! Pete also noticed the replacement diaphragms do not have the shield.
With the RSTs I have the shield seems to be glued on I will take another look in the AM,
I also have the aluminum versions and replacement domes coming tomorrow.
Guess xmax's age.
My guess: 15. His grammar is passable. His trolling is good.

Hey, I was looking at this from a different perspective and was trying to time align tweeter and woofer, and ended up here on this thread and using the same over the counter WG. I'm still waiting on some drivers but have some RST-28F data that may pish the discussion along.
