A few decades ago I worked in high-end audio, and we did carry some more obscure speaker lines.
What I learned back then is that not all speaker manufacturers build their own drivers, they oftentimes spec out their needs and have them built by other companies, and would order a bulk number of raw drivers, essentially predicting how many they would need for manufacturing and post sale service.
We had a few manufacturers who never seemed to have spares available, especially for our customers who tended to blow tweeters.
Something to think about, if considering a more obscure product.
