Much appreciated but unfortunately my tweeter seems to be of the older version(?) even though it's a 200A. After fitting the 1S diaphragm, the sound was ~10db lower. Not sure if it's due to the impedance. Also, the 1S looks very different than mine. The part number I'm after is D8R046TI. Apparently it's 4ohm, which may explain the lower volume output.
