$780 isn't bad at all if all of the drivers work and you can go pick them up.
Not sure how those fronts were done because from the looks of the squawker face depth, it looks like a normal thickness. Also the peak of the bass front looks right, yet there's an overhang seemingly everywhere. If you look closely, there's a horizontal seam just below the squawker like the entire top section front was replaced. Doesn't explain the bottom, though. I'm intrigued!
Did you get them, @Mh3pworth?
