Any ideas about the electro/complextro bass stab? (Samples included)

[Aleksandrovich]

I've been listening to (and producing) less and less progressive house and have been moving towards electro recently. In the case of most electro that I listen to, I can estimate how specific elements were made, but this sound continues to stump me. Here's a quick audio file demonstrating the sound I mean in a couple of songs (I play the sound twice by itself and once in context):

I get that it's pretty basic (some thick saw- or square-based sound run through a filter with an envelope), but I can never get it sounding as thick or beefy as these do.

Amyway, any thoughts on how to make it? If any of you has made something like this yourself and wouldn't mind sharing how, could you give some insight?

Thanks.

Saw wave,maybe with sqare lower octave, decay based envelope,saturation and bitcrush distortion .
