Soundbar at the back of the room (behind bed)

[DaMacFunkin]

Hey Guys

So basically i wanted to find out if this is a good idea and if it would work or not. So my bedroom has the door to the right and my parents bedroom right behind the TV. So when the TV is loud and the door was open it would disturb other people. Also, i can not loud the volume too much because directly behind the TV is my parents wall and the walls are not well sound proof. I would love the sound to come out from where we are lying on the bed so that i can loud it up a bit more and it would not be loud enough to penetrate into the other room. Now i was thinking about getting those bluetooth sound bars and putting it behind my bed so the sound can come from there. I know soundbars are meant to be put above the TV or below it but would this still work practically.

The obvious problem with that is back to front sound, so if a door closes on the left of the TV you will hear it on the right.

Well I could just make the sound come from the soundbar behind the bed so nothing comes out of the internal speakers right.?
Would there be some sort of lag or is this a stupid idea?
