You will probably need the part # oFocal f the specific driver for anyone outside of the official distribution chain to help you out. Once you know that, you might even find one on fleabay.

That may very well be the case, but I would still speak to someone at Focal before you buy anything. Since Focal makes the speakers and the drivers, they may not make the drivers that go into JM Labs speakers available to anyone else. If I remember correctly the US importer is Audio Plus Services. I haven't thought about Focal products in a long time, so I may be mistaken. But try them first.
