It's a technique that may require some sample navigation.
That's why we thought the best way to select your desired sound is to search amongst our sample material by searching for rumble sounds such as:

or

The whole construction model relies on getting the nice techno rumble you would get in lots of mostly techno tracks, such as the ones from Drumcode, or Suara, by using a natural recorded ambience rumble.
1. Select the section you find as useful, by matching it with your kick sample/reference track
2. Trim the selection and transpose at your taste
3. Make it mono, apply a filter and cut high frequencies, and a LFO tool, or other compression to fit it in the track
Hope you'll find this quick tip useful, and don't forget to navigate our library, we have plenty of rumble sounds to be explored:
