I was a huge car audio nerd in the late 1980s/early 1990s. One bullet point you could expect to see on most subwoofer spec sheets was 'KAPTON' voice coil former. I often wondered why that fell out of favor, but it seems that we know the answer... Most kilowatt subwoofers now use aluminum or copper voice coil forms for what I can only guess is that they are just better...
