I have a sound bar with a sub and it is certainly not as good as a full surround solution but I really don't care. I'm up at 4:30am watching F1 in dialog mode so I can hear crystal clear voices and a little bit of rumble from the cars from the sub all in trying not to wake up my wife downstairs so it's all is good. :) The main reason I have it is because it does not interfere with my main 2ch system that has to live in the same room/loft with no interference. For example, the sound bar sub sits in a non-optimal position so main system sub can be placed where it sound best.
