If you still need to push it in, it wasn't fixed. And what if it gets loose after playing music for a while? I just don't understand why can't they design one that is fastened in there securely. This isn't a problem in any of their other high end/performance offerings so clearly it can be done.They did fix it, it just needs to be pushed in.
When I had the R3, when you lined up the mid driver with the shadow flare the shadow flare would sit deeper than the front baffle itself, creating a circumferential ridge.
On the R3M, when pushed in (after shipping movement), the flare lines up with the mid driver and baffle almost perfectly.
@amirm did you get a chance to verify the shadow flare was pushed all the way in? The dip at ~1.2kHz definitely seems like it could at least in part be due to the shadow flare and not just diffraction.
