When it comes to Poly drivers,I haven't heard any speakers that use them since I owned a pair of Kappa 9's many yrs ago.Several speakers of that time period used Poly woofers and maybe other drivers like mids.I can recall a weird sound from them that just wasn't natural and I changed both of the 10 inch woofers to paper cone woofers,It's been so long ago that I don't remember what I used.
There is some great technology in very thin but rigid thinned epoxy nano spheres that are a hand me down from the aerospace industry and make great paper cone coatings,quite similar to what Zu audio speakers use.
