Infinity Owners: New EMIM Diaphragms Available

The patent on the design must have expired! Infinity was really mean about not allowing the EMIM design or parts to be reproduced. Just in case (if I still owned some RSIIb)I would buy these and some replacemments.. Harman Corp may decide to try to enforce some sort of patent infringement anyway.
So buy now in case this infringement is challenged.
Just my opinion.

I don't see how the patent could not have expired by now. These speakers were made in the early 80's, and US patents only have a 20 year life maximum lifespan from time of application filing.

True, but the various ways companies use to extend patents... and the Lawyers lining up is always threatening, maybe enough to stop a small company from continuing making a part just from the threat of being entangled in legal battles. i would still be suprised if the parts are in production very long.. Just my opinion. A LOT of EMIM owners out there hve been looking for parts for years...
Like I said, buy the parts while you can!!!
When I owned Infinity with EMIM those inner diaphram plates were the main bottle neck. Once damaged, you were finished.

In any case, if the EMIMs sell well, then EMITs will follow, and after that perhaps L-EMIMs. If those sound as good as the EMIMs, those old Infinities will be giving some very expensive new speakers a run for their money!

By the way, the owner of Apogee spoke with Harman, and they said they had no plans to ever make more themselves, so it looks like it's OK with them.
