Got my GRS-10" driver!
I'm surprised how hefty this is, it's really solidly built.
I do want to say tho, that there is actually the full 56 magnets (28 per side) within the driver, not the 42 listed in the Parts Express page.
Heres some pics I took:
You can see in the 2nd pic that there's a strip of rubber that hanging off, and that seems to be their attempt at covering the edges of the diaphragm that came loose, but considering how well built this is, as a whole, the edges are a nitpick on both of these models.
I'm definitely interested in seeing how it measures tho, cuz thats where it matters, I do wish I had a Neo-10 for a proper side-by-side comparison, but I'm definitely interested in what Danny has in the works with his own model.
