SOURCE: how to set up a soundbar with a subwoofer

The subwoofer deals with low frequencies, which are not very directional (ie, it's harder to tell where the sound is coming from).  So where you put it isn't critical to the sound, provided that it's not behind curtains or something that will soak up sound.  The bigger speaker you have in your subwoofer; the less important the position is.
Putting it in a corner is something you're going to have to try, but you may even end up with better bass if you do, as a corner can act as a soundbox and emphasise bassy sounds.  Conversely, your subwoofer may not like being in a corner and interference effects from the sound reflections could degrade the sound.  Like I say, try it and see what it sounds like.  It depends upon your subwoofer, what else is in the corner, precise positioning, and how reflective to sound the corner is.  If it sounds terrible, move it a few inches and try again.

You can put it in front of you next to the TV, no problem.  The only downside it it's a big ugly box.  My wife always makes me hide my subwoofers behind something.
