Got sent these tweeters to trim down the plates and take a look at their construction...
Interesting design as they have the exact same felt as RD0's but they are suspended above pole-piece by 3 glued-on rubber tabs and about 1/64" gap for airflow to the back chamber with NO stuffing in the tunnel.
Thru hole is 0.410 diameter with @60 degree angle on the pole-piece face. Back chamber has a felt pad and chamber is made by the outer steel housing.
Both domes are 28mm, Ohm out at 6.4, with true aluminum VC former that is submerged in ferrofluid. And there is a thin gasket between diaphragm plastic and top plate (like RDO's have)....
The bezel mount holes are spaced exactly 2.11" center to center and M4 x 0.7 thread pitch....
