808 or?

Hello friends.
I know this is one of those thread's but here i go.
This has been stuck in my head for a while now.
I need to find out what and how do these dudes get that bass, i tried messing around with 808's, but can't even get close to that.
If you have any idea or some tips that could help i would appreciate it.

Do you have Massive?

Pretty similar to this sound:

if you don't have massive you can do similar sounds in any synth where you can modulate filter cutoff with an adsr envelope.
