Well-designed mineral filled poly cones can sound quite
good. I lean towards ‘paper’ for cones, but I also like good Kevlar ones. I
think Rival gets their Kevlar and Carbon materials from Japan. I know they have
a 7’’ Kevlar that hovers around 50 Hz with about 90 db. 2.83v.
Maybe it's an age thing, but poly=plastic always seemed cheap fake and well plastic. Aluminum= airplanes and rockets. Paper= airy, light as a kite. Carbon fiber= composite sports car fast. Kevlar =cut resistant, bullet proof. Yeah, it's 8:00 on Friday night and I'm typing a note here...
That used to be my feelings/thoughts also, then Jeff Bagby pointed out world class AT (sorry, can't remember what the initials stand for) mids/woofers have poly cones, and high end Morels have poly cones. I have yet to hear either of those, those. Correction - ATC mids/woofers
JR my comment was meant to be snarky but after I read it again it seems so, sorry about that. I was trying to say I was looking for some user experiences.
Any way the Cirrus White is probably going to become my chocolate cake project.
I’ve been following along on this. I’m looking for a much better woofer than the SB17NRX35. There nice, but low end extension is not. Anything beyond Xmax and there noisy.

SB17NRXC35-4 specs look good for a 6'' woofer at $60 a pop.
