Hi all, first post but long time KEF lover. I 'finally' found my dream speakers that I couldn't afford years ago; a pair of very nice KEF 107s (series 1). I suspected when I bought them the surrounds would need to be re-foamed, which they do. What I didn't suspect would be the woofers would be blown (shorted voice coils I suspect). I did some research and called Madisound as they have SEAS drivers which 'should' work as replacement as I can't find a pair of original KEF drivers. Link to the SEAS drivers are here:


Has anyone ever tried these in their 107s? If so, what are the results? Are they a good substitute or am I relegated to waiting for replacement woofers to show up on ebay someday? The only problem I see with the SEAS drivers are there is no force-canceling rod that can be used between them (as with the originals). Not sure what impact that would have. Also, not sure if the KUBE would interact the same way with the replacement drivers as with the originals. Any ideas on this?

Another small line of hope I am hanging on to is a place in florida that allegedly refoams AND does voice coil work. They are here:


No word back from them yet though so we shall see if that is an option to explore.

Any other options I may have not considered? I called KEF America, but they are elusive as well and waiting for a call back from them to see if they have replacement drivers (very slim chance I figure since these have been out of production for so long).

I appreciate any insights the group may have and look forward to contributing where I can.
