Is 1990's equipment vintage?

To OP’s question, NHT classifies their first generation 1990’s line as “archived”. Next gen Speakers  are their “classics”. 
So my opinion is If it’s old and has special charm then it qualifies as worthy of being vintage. 
What is special charm? With some JBLs it’s their ability to pound out bass. Marantz, yeah ...the flywheel. Kharman Ghia shows that butt fugly is a special charm.  Phase Linear’s special charm - it must be good if it weighs this much.
Crazy Eddie’s charm was a store that looked like the back of a warehouse. My charm, musta been that Nik-Nik or Huckapoo shirt that attracted them.

if you don’t know some of the things I’m referring to I’m sure there are memebers on this forum that can enlighten.

Erik, your opening line didn’t have much umph but this thread developed nicely.
thanks.

@brownsfan Yes, a man of few words. My drivers were pretty easy to get out, sticky, but nothing a little patience didn’t solve. Are you upgrading crossovers from the originals? Curious, if there is a known upgrade I’m keen to learn more.

@au_lait,  I am attempting an upgrade.  I will PM you.

1990's characterization falls into Vintage - Items that are no less than 20 years old

I hear what you are trying to say, but I don't think that I'm going to rely on what a manufacturer does for the convenience of organizing it's online support as definitive here. :)
