How to make bass to shake the foundations?

Hey all, i’ve heard this kind of bass in a few tracks now - once a few weeks ago in a club in berlin. It nearly brought the walls down. Can anyone give me a few pointers on how to create a bass like this on the voyager?

Thx,

include one Osc of low octaved triangle and you’re halfway there!

Thanks Filtered, sounds good )
