Is subwoofer required for soundbar operation ?
Do I need a subwoofer added for soundbar to enhance more clear and crisp TV sound output? Or will soundbar work for what I want without a subwoofer?
It depends on what you're using it for and how you like to listen. If you want big movie sound, probably go with a subwoofer. Just listening to regular tv, sports, even most music, the bar is good, but I'd still use the bass boost.
