Hi Owain
Sounds like they are gonners. They voice coils start to drag when they get over hot, they may stop when they have cooled but it is unlikely, It usually sounds as you have described barky, scratchy etc, which is the expanded coil catching the sides of the magnet on its travel.
If you want to test the damage, place the cab on its back and push the coils gently by hand and if you can feel it catching then its buggered.
If you cant move it at all then it has welded itself to the magnet, This has happened to me before when i lent my monitors to an ex student for PA hire, how he manged to blow 2, 15 inch monitors capable of handling 500 watts each and not realise at the Head of Steam is beyond me
Tell Tim, Phil Poolan at work has an old pair of Burman 12s which he has no use for.
Cheers
Dave
