Here's a great system almost identical to one I put together for my brother, and it sounds absolutely fantastic for movies and surprisingly good for music too. Includes a sub that will get you down to an honest 20Hz so you'll really feel earth-shaking explosions, etc. in your room, and the critical center speaker really delivers the goods. This system will make your soundbar sound like a bad joke by comparison. All of it is new with warranty, and the total cost is within your budget at $1978. All you need to add is cables/interconnects, and @grannyring here can build you some really good Dueland wires that'll work great and won't cost too much. Hope this helps, and best of luck in your search.
