The underlying issue it addresses is easy: built-in TV speakers sound thin and muddy which causes dialogue to be difficult to follow and diminishes your enjoyment of shows and films. The Bose TV Speaker fixes it by employing two angled full-range drivers that produce a broader and more natural soundstage. Rather than having sound directly emanate at your face from one point, angled drivers reflect sound off your walls and bring it to life and opening it up, as it were.
