Hello. I currently have a basic Vizio SB3621 n-E8M soundbar hooked up to a Samsung TV but when my wife and I are watching shows or movies, the ability to hear dialogue over background music or other sounds is really tough. We want to stay with a soundbar and not put separate speakers in our very open space living room (with vaulted ceilings). Can anyone recommend how to improve on this issue via a good soundbar in the $300-$400 range? Thank you.
