Your own Speaker Brand?

Just a further thought: if these are DIY speakers, there's no problem with giving it a model (not brand) name and naming the drivers. It's done all the time.

If you are contemplating a commercial venture... I don't like the idea of "name-dropping". To me it seems amateurish. Personal opinion. I doubt, though, that there would be a problem in saying that this Brand X speaker is a development/fruition of your old Model Y that used Brand Z drivers(?). But I don't know for sure...
