RE: I use 2x Rythmik F12G

I haven't heard the F12 with the Aluminum cone woofer, so I can only repeat the advice I got from Rythmik, which is to go with the GR driver for a music-only system. According to Rythmik, the GR (paper cone) driver offers better low level dynamics. It also has a more extended response at the top of the frequency range so it is a better choice if you're using higher crossover frequencies. I also read opinions from other Rythmik owners who think the GR driver has better transient response or sounds "faster".

The advantages of the GR driver are due to its low cone mass. The Al cone woofer is heavier, so it will be somewhat less efficient and require more NFB correction via the servo. But it's also stiffer, so it will remain pistonic at higher SPL than the paper driver.

Rythmik isn't making a general claim that paper drivers are better for music. Obviously, cone material is just one design consideration. But they do think that the F12G is their best sub for audiophiles.
