Bass in "House of Cards" soundtrack

So, has anybody else heard the really cool bass effect used in the House of Cards (Netflix Series) (I'm sorry, I'm blanking on the composer's name) soundtrack and thought, "I've got to try to make this sound..."? If so, any success? It sounds like a good bass sound with the initial attack removed but not really... the sound still has a "beginning" but softened.
 
Best,
Rob
