If somebody has the MBM51s Dome in use it may be interesting
for you to know there seem to be 2 versions.
I had a newer looking pair ebayed and put them in as i thought
newer is better. But to my surprise the newer ones sounded
muffled and unprecise! Measuring Z shows a damping at resonance.
I looked further and found a muffing material in the coupled
casing. Remove this when you have this version, it leads to a
much better resolution.
btw. if somebody is interested, the switch had some changes
meanwhile and is "Finished" for the 10xxx time
