Replacement diaphragm for the Peavey RX22 high frequency compression driver.

There are several improvements in the RX22. The design improvements of the 44XT were implemented into the new design of the RX22. The light wieght titanium alloy dome and diamond suspension are now one integral piece stamped on a custom tooled fixture that also uses other proprietory processes in the forming. It now has a seperate coil form that is glued to this one piece dome/suspension, using adhesives and processes that were developed for NASA to keep the tiles on the space shuttle.

On the previous model 22XT the dome and coil form were one piece but we had a seperate Kapton suspension.

The RX22 also has a newly design phase plug that has a bit less of a radius to it, and the dome is also allowed to sit closer to the newly designed phasing plug. All of this contributed to an increase in both frequency response as well as transient response.

It is because of these differences that the RX22 diaphragm kit can not be used on previous model 22 drivers (22, 22A, 22Ti, 22XT). If you put try and use it, it will probably bang against the closer surface of the new phasing plug and under go failure.

We now have a diaphragm replacement kit called the 22XT+. The 22XT+ is the replacement diaphragms for all of those models prior to the RX-22.
