B&W CDM2 - looking for replacement woofer alternative

It is understood that only the original woofer will net the original result. But if that is not a requirement, what other drivers would FIT and have similar characteristics.

There are THOUSANDS of example where (particularly for vintage speakers) where users have found replacements for drivers.

Trash vs. spending a few bucks and still use the speakers (in a lesser role as originally designed). I understand that this may not be the best place to extract such ideas from the audiance considering the amount of pixel dust that is floating around here. But there still may be some more practially inclinded people here who know the insides of their speakers.

If it isn't just a refoam, then your best bet is E-bay I think.

Not considering repair, just replacement with something that a) (most important) FITS (phycially) and b) maybe someone close (for example another B&W driver from another speaker). 

Brother, have you considered a speaker kit? :)

If you don't find a drop-in replacement, then you end up with a lot of adjustments and then you end up having to do a lot of measurements and crossover changes, and by that time you might be better off building a nice 2-way speaker kit from scratch.

Personally, you are better off selling the pair you have as is.

PS - DIYaudio is a great place to ask for help like this, lots of speaker builders with expert advice who may have a driver, or may know what drops in well.
