...do great speakers increase in value over time in the vintage market?


Hello to all...

I have a pair of JBL L25 "PRIMA" speakers, made 1972, case in 7/10 shape (not repainted), surrounds on woofers reformed several years ago, grill cloth replaced several years ago, includes JBL badges on speakers. Original 1972 price $169/ea. 

Recent searches of this speaker in the vintage market show prices 50% OR MORE than the origional issue price: ???

Is this that good a speaker design? - I have read comments saying it his/was one of the best speakers ever made by JBL (at that time?) - and I do luv their sound (which I now wonder if I've ever really heard them?) especially with well-recorded jazz and have the ability with little power to ROCK OUT!

(Would greatly appreciate any comments by those who have/had these over the years...)

DO GREAT SPEAKERS INCREASE IN VALUE OVER TIME, or do/should all depreciate in value...

The Dunlavy's still have a following. After going to multiple audio shows, I'm still quite content with mine in multiple systems.
What douglas_schroeder said, which should be obvious. I think you would be hard pressed to find very many pieces of audio equipment that are worth more today than when new when inflation is taken into account. There will always be exceptions to the rule.
My fellow Asian folk will always more for well respected Jbl or Tannoy , altec Lansing driver , for that kind of moneys they spend I rather pay for recently made and still have moneys left for more records 
This hobby doesn't seem to have as many "collectors" as other expensive male hobbies. People want their money to buy great sound above all else. Classic cars, this hobby ain't.
