There is a great thread on A4 bass you should read through: A4 deep bass tips?
Something I hear when I listen to modern EBM, like Covenant, I love this song of theirs “Judge of my Domain”, or Funker Vogt, especially a God Module remix of Youth Code’s Sick Skinned, the bass is huge and mix dominating.
It sounds like a lot of the time there is some unison in the bass. Your in luck that the A4 happens to have Unison, so after you read through that thread and get a good basic baseline going, head into the poly settings, turn on Unison and increase the number of voices, detune and maybe even spread.
Also, the bass in EBM sounds super compressed. So your going to need to run it into a compressor, hardware or software that the A4 alone doesn’t have and squash that signal for extra loudness.
You should be close at that point.
