It's all in the bass, man
Dude, piece of friendly advice. Get the Klipsch speakers, if you must, but for god's sake, try to get yourself emotionally unhooked from wanting one of their subs too. Why? Because:
1) Everyone who has responded to your thread is dissing the Klipsch subs in favour of an SVS. They're doing this for a reason (sound quality, value for money, and they want you to have a great experience).
2) I have an SVS SB12-Plus. It's amaaaaazing! One of my mates was amazed I'd spent so much - relatively - on one piece of kit. "Bass is just bass", he said, "isn't it?" No mate, it isn't, and the very fact you say that just tells me your sub is a piece of low-end high-street crap - no offense.
There are smaller subs - I think AH reviewed one recently that you may have seen. Keep looking. I even saw a picture recently of one "hidden" beneath a coffee table. Wouldn't be my ideal, but if it's that or nothing, needs must. And you MUST have good bass. So..
Chin up
Powder dry
Klipsch sub bye-bye
