Driver details for Audio Artistry Dvoraks

Hi there:

Someone near me is selling a pair of Audio Artistry Dvoraks. Since they are sort of one of the precursors to the Orions, I'm thinking it might be a good choice for me.

But these speakers are old, and the manufacturer is out of business so I worry about driver replacements. Does anyone know which drivers are included in those speakers and whether they can be found anywhere and replaced by someone with mild DIY skills?

Thanks.
