Sub Bass in Dubstep

Sub Bass in Dubstep

I’m wondering how you guys approach sub bass in dubstep. If my ears are right, a sub bass is usually layered under the wobble and its cutoff is LFO modulated with the main synth or it can also just play under the synths. I made a recent dubstep track and one of my falling points is the sub bass. Any tips or thoughts?

sine wave, LFO on volume for wobbles

I dont really knoe if its the correct way to do it but I use sine wave too with Lfo on the Freq Filter around 230 hz and resonance on minimum.

Sub bass is 80hz and below. its what u feel rather then hear.
