If there's no sign of burning, then attempting to move the rear plate with a sideways blow from a rubber mallet might just re-align the assembly.
I haven't disassembled anything, but at least prior to taking anything apart there are no signs of burning. This rubber mallet approach sounds about in line with my skill level, so I will give that a go when I get a chance.
Thanks again for all the advice and insight.
I fully understand. There's too much needed to be done to these speakers, making them beyond economic repair.which isn't in the cards
Without any particular attachment to them, it's time to cut your losses.
Check the spider for any signs of burning due to an overheated voice coil. If visible you will almost certainly require re-voice coiling.
On second thought maybe I don't know what burning looks like - I took a photo with my phone and it looks different than when I looked with my naked possibly bad eye. I've attached it here - is this burning?

Is it just a trick of the camera, or is the black voice coil former tilted to the right (i.e. not truly vertical)?
I think it's a trick of the camera.
