Where can I find replacement speakers for the Soundlink Mini?

I plan on following the relevant guide for replacing my generation 1 Bose Soundlink Mini. The guide is very in depth, including necessary tools; however, it doesn't list any relevant information about the speakers. The guide gets to the end where you remove the speakers then, bang, thats it, no more help.
