My father in law has a pair of SDA Compact Reference speakers that he bought new back in the 80's. I have them in my house now so I can clean them up for him (there are some scratches on the cabinets and some paint, but the drivers seem to be perfect and they sound great). Did Polk manufacture a matching stand for these speakers? He doesn't have a set and I was thinking I would pick him up a pair if there is such a thing. If there isn't a specific stand for them, what brands and stand heights do people recommend? These are pretty heavy speakers and they're wide so I'd like to make sure I get the right thing.
