Soundbar need to have proper room and setup to sound nice, mainly its due to convenience only for people who dont mind. If possible its always better to get proper speaker and do up the wiring.
Got a friend who have a Yamaha YSP4000 that he setup for a gaming situation in a seal up room with projector and proper gaming stuff (PS3, Gaming PC and such) where it make it as you are indeed in the game, bullet coming from the back and such.... But for his AV need, still its a normal multiple speakers setup. But that gaming room only around 7' x 8' only slightly bigger than a toilet.... all side wall with a solid wood door... really seal room... lucky got aircond or else die....
