A useful trick then is to try PHASE INVERSION on either the bassline or the kick drum, compressing the kick and bass together and/or avoiding to place a bass note on top of a kick drum. A common problem is that the bassline and kick cancel each other out due to PHASE problems (easily demonstrated when DJ-ing, if you play two tracks and have them beatmatched, it's important to cut one of the tracks' bass level or else the kick drums will cancel each other out and the overall bass level is lowered). This is where basslines and kick drums have their most important sounds. Too much volume in this range makes your mix sound «muddy.» Use this range to fatten up your kick drums or sub-bass patches.

Sounds with these frequencies are the most powerful ones, and they will take up a lot of room in the mix. This is the super low-end that can be felt physically by your body on a good subwoofer/sub-bass system.
