Good question!
I endorse your question. Looking at others Nirvana drivers, the VC is referred to as KSV.

Searching on Google for KSV VC seems it is a usual material in pro audio speaker, so it is not a fragile material as it would looks.
Voice Coil products, buy Voice Coil products from alibaba.com
It make sense use oldfashioned Kraft VC, in the Nirvana fullranges, as they are a classic (small Xmax) project.

A brazilian here...welcome !
I like a lot of full ranges, too.
The paper is the best material for the voic coil former, but do not support very high temperatures.
With the news papers, this do not occurs...
See this article...the PHY-HP speakers use Vellum paper...and cost 1500 euro each !
