Does anyone knows what brand they use for Kevlar speakers, I've seen some guys offering me cheap china made kevlar speakers which I think they are fakes, low quality which will last a year or two. I only know Focal, and Davis Acoustics that makes kevlar speakers. Does anyone with Nirvbkr speaker know the brand they use?
I would also like to ask who uses carbon fiber speakers, are they as good as kevlar speakers?
Thanks,
