I have recently acquired a pair of S45.2 speakers from retro junkie of ebay fame, one of which was described as having a woofer driver seized, not taken them apart as yet due to the volume of mundane tasks dictated by the woman in my life, however I suspect a misaligned magnet as this seems to be the most prevalent thread posted in these rooms. When I get permission to revert to my own activities once more I will chronicle the excercise along with some pictures.
Finally got round to having a look, first one has a couple of heavy scratches on one side, the cloth looks worse for ware in one corner.
This will require both speakers being recovered....
the bass driver is frozen solid, the rubber mounts look in good shape however
finally getting back to the proper jobs in my life, removed the driver from the cabinet
however I'm at a bit of a loss as to the best way to get into it
I think the grill type cover needs to be removed, the cobalt magnet looks like it could easily be damaged however
So.....any advice from those who have been here before would be welcome
Great speaker's I am yet to hear better waiting on some s75's
good luck with your project

Irata has documented the procedure very well in this blow by blow thread......
S45-2 speakers are very good playing speakers and definitely worth to restore them.
Wood work could be done with great success, you will find here veneer repair here in forum. Take some drops of hot water to the wood scratch (only) or use steam from boiling water, hot water will help to recover wood. After some hours clean veneer with isopropyl alcohol and take sand paper ...
I was trying to repair dislocated magnet using above mentioned thread and no luck, I was not able to center the coil inside magnet.
So another solution for me was to ask Dillen (Beoworld respected member), he helped me to source woofer easily.
Thank you for your encouragement, I will certainly give these speakers my best shot. Gripped the errant driver in a vice this evening and was shocked by how easily the magnet detached from the housing, it was almost like the only thing holding it in place was the paint.
The pole piece is still securely fixed and looks central in the magnet, as I see no reason to disturb it I'm going to clean it up in situ.
The dremel with a wire wheel lends itself to this task quite well
the magnet and pole piece now look acceptable, and feel very solid.
