Klipsch didn't insert the vulgarity thoughtlessly, and I'm sure they have deliberate reasons for using that exact phrase. I'll speak for myself, I don't like it; I find it tasteless. It's 1970's thinking. In fact, it's 1970's thinking that didn't work even in the 1970's.
I already have a Klipsch sub, but with that kind of advertising it doesn't make me feel like I want to buy another. I'm just not the kind of person who has such anger, that I want to buy a product just to piss off another human being.
Personally I enjoy the unapologetic passive-aggressive old school marketing. I think nothing of it and sometimes it makes me grin. Being politically correct and nice is for Bose fans.
