Where can I get this low end sound?

[DWKNS]

Hey guys,

I'm trying to pinpoint this common sound that I can't find easily in my library. You can use the below Youtube link for reference (Drake - Heat of the Moment). On the low end of this song there's this smooth bass sound that's not too gaudy but adds an amazing element to the song. Extremely common in R&B songs. What is it and where can I find it? I don't know if it's a sub bass or what.

Thanks for your help.

can you give a minute when the sound appear, because there is a lot of lows in this beat.

First time it appears is right at 0:49 and every other chorus appearance throughout the song.

Last video I posted was slowed down. Here's a better video:

just a pair of saw-waves slightly detuned with minimal filtering - adsr for the vca is something like 1-7-6-2
