Bass reverb from King Alpha and other artists

Can someone explain to me how to create a “bass reverb” sound which blows me away on a soundsystem session? Examples of what I mean:

King Alpha “Wizard Dub”:

Start at 1:00.

Different, but very powerful to my ears:

Jah Baker “Powerhouse Dub”:

Start at 1:35.

Violinbwoy “I Dub Be Lion”:

https://lionsdensound.bandcamp.com/track/b1-violinbwoy-i-dub-be-lion

Start at 3:45.

There must be some trick to it, because while I use different reverb effects on my releases, they sound nice when listening at home, but you don't hear it on the soundsystem like you hear these tunes.

Generally, I LOVE those reverb effects on bass. It drives me positively crazy. How about you? Discuss. :)
