I think the Klipschorns or other Heritage models fit this topic altough some tend to drift towards a more neutral sounding speaker with age. The Klipsch Heritage speakers have been relative unchanged for decades and still have a fanatic following. 1970's/80's and older models are frequently listed on this site.
I have a pair of 1976 Klipsch Cornwalls & 1976 Heresys. They are great for home theater, but I'm considering something that is more pleasing or not as "harsh" for music. I restored a Dynaco ST-70 with some mods but still need a tube pre-amp to see if that tames the Cornwalls more to my liking or if I should look at something else.
This is very interesting because you can buy many of these vintage speakers and achieve perhaps better value than new. In addition if you do choose to upgrade they often hold their price or even appreciate.
