Anyway, we are not talking about buying decisions and thought processes. I wouldn't compare speakers and cars, speakers rarely blow up and never crash unless you drop them somewhere.
If you buy the right loudspeakers they can be repaired upgraded long past manufacturers existence. 

As someone who has been down the road of procuring obscure/vintage speakers, you can consider them without the attendant risks, but it's foolish to do so.
