Looking for the advice of any audiophiles that might happen frequent the forum...

I'm after a decent soundbar to pair with my Samsung TV. Ideally looking for something under £200 so nothing high end but just to improve the overall quality ofthe sound.

My main question is, are soundbars suitable for a relatively small living room which is part of an open plan kitchen/living area? Seen some posts online that they don't work so well in open plan spaces but I'm wpodering if that's just for very large rooms? My room is rectuangularly shaped, quite long and narrow, is a regualr soundbar suitable?
