Will this bass speaker fit Korbanth/Parks Graflex 2.0?

[erlomd]

since stock is gone on mostly everything lightsaber oriented...its a little hard to find simple parts anywhere.
I have been looking for the 28mm bass speaker that TCSS sells and have come across a couple of websites that sell similar (if not the same) speaker to fit the Korbanth/parks Graflex 2.0.

This one looks promising, but have no idea if it will fit? or work for that matter...



OR...

If anyone here has an Idea of what will fit or can recommend something different...then by all means let us know :)
