WTB: MW7100 or MW7010 for LS50

soiset

One woofer voice coil of a pair of LS50's that I own is misaligned and causes a nasty crackling within a lower freq range, so I need to replace it. The stock item is MW7100, but Ken tells me that the MW7010 has the same specs and can be used.
The MW7100 was used in the LS50 and LS90, and I know the MW7010 was used in the RT12. If you know any other models that use either of these drivers, please let me know, as it could aid in my search.

Thanks
