Ampeg j20 owners

[Garage Dog]

Has anyone replaced their speaker in their J20,have you found a decent home for the original alnico speaker.I thinking about trying it out in a Blues Jr if it will fit,any thoughts.

I put a C-rex in mine; love it. I read (probably on this board) some one say the stock 12" from the J20 sounded great in a particular Vox amp.
