Deep Saw Bass Sound

[Nevs]

I need some help with my understanding of this type of sound. I've been trying to reproduce it as I feel it would be awesome to include in a production, but I can't seem to get it right.



The sound in question is at 1:07, and 1:13

It is heard throughout the song as well.

It sounds to me like a saw tooth wave layered with a sub, both are dropping in pitch. But I can't seem to make anything that sounds as weighty and heavy as the sound in this song. I've heard similar sounds in tracks by Seven Lions and Xilent. Wondering if anyone could shed some light on this for me, as it's not as simple as layering a Reese and a sub drop together.

I know Au5 uses Razor a lot, can this sound be achieved in something like Massive or Alchemy?
