Paper Cones in HiFi?

It takes a person who judges sound quality by dollars to buy a bargain!  :)

Then, they will pretend they have the "best" sound. It's how budget HiFi works.  

Mozart….just a bit of effort on your part will reveal that Vandersteen builds unique balsa core, carbon fiber and aluminum honeycomb ( sub ) cones for integration into Scanspeak bespoke frames and motor assy, including unique to Vandy aerodynamic structures. 

A partnership with Scanspeak that spans decades…

You may on self reflection discover that this post is not really a reply to you…

Paper vs Balsa C/F with the ruthless truth machine German laser…

Listen and measure…or wander randomly

With loudspeakers, it's the total design and how the parts are utilized to achieve the designer's end goals whatever those maybe focusing on one aspect of a transducer's design is moot. 

Scanspeak makes some fairly expensive paper coned woofers.  I don't think they think that paper is crap.  A local dealer that builds its own custom speakers just finished a pair that utilizes 15" paper coned drivers from Scanspeak.  The drivers cost the dealer $2,000 each.  The speaker just came in and the crossover has not been mounted so I haven't heard them playing, but, I will get a chance.
