    Perhaps I missed something?

        Perhaps PE inserted the wrong photo.

        • 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.

                • New RST28 is on the right.

                    • It's a nice fit, but the finish seems quite rough. Has anyone suggested an advantage to the roughness

                      • It's not as "rough" as it looks in this pic.

                        • Are there dimensioned cross sections available for the wgs you're using, other than Pete's and other designs contributed by forum readers?
