I found out that I have a pair of S45-2 with stucked bass drivers. Obiously loose magnets, and no more spares aviable. Donator speakers are not an option to me, it still leaves me with pair of speakers wiht broken basses, and that bugs me for sure.
So, I have to do something about it.
First, lets have a look inside, not much can be done from here.

I put a plastic sheet between centerpole and voicecoil to prevent any damages, then drive "stuck" on it.
Well, if it isn't broke, you can't fix it. So lets break it.
Supporting magnet on edge of table, "stucked" side down , I tap "gently" with screwdriver and hammer to break backplates glue, and backplate can be slided off. Slided, cant lift.
And magnet also.
Then to electrical parts, first wires.
Couldn't melt the glue, so have to cut my way here.
As you see magnet is back on its place. It is because voicecoil could easily get damaged othervice.
This was almost "Haven't a glue" situation. Surrounding comes off with bare fingers with no resistance at all.
Her it is. Bits and pieces.
And all cleaned up, ready for reglueing.
This is my favorit, Never has let me down.
First round, everthing centered, not too much pressure, I like to actually have some glue there.
It is easiest if backplate is in wise, few millimeters below toplevel, in that way, when magnet sucks down (and it does), you have still possibility to adjust shims if necessary. Shimmed in forehand, no otherway possible, and they must be off from backplate, we dont want to glue them there.
Removed from wise and pressed to end, ready to let dry under modest pressure.
Here it is. Reglued body of bass speaker! Yes!
All electrical work back together again. I started cautiously with small dots just in case something goes wrong.
I tough that I did take pictures from assembling cone, but I can't find them, stange. Anyway there are lots of pictures from procedure (refoaming) on this site. Meaning jump to dustcap after testing that cone movement is fine.
What we have here? A S45-2 with happily woofing woofer!😁😁😁 Tested with YELLO.
