KEF 107/2 low frequency driver replacement

I am looking for the low frequency drivers for the KEF 107/2 speakers. Has anyone experimented with alternative drivers? I cannot recone since one of the magnets has shifted and cracked. Help!!!
hi, sorry i have no answer for your need. in fact i will ask you something:
I have a pair of 105-2 speakers, do you know what is the main diference beteween mine and yours ?. Right some minutes before i started a new thread, asking wich could be the best way to biamplify them as I know the 105-2 have only a set of conection for one amp and not for 2 as yours.
Have you tried to get original parts from the factory?.
