The picture quality of today's HDTVs is fantastic. But frankly, the sound can be about as flat as the panel. Samsung's HW-E450's dynamic, full-bodied sound will dance pirouettes around your TV's tiny speakers. This sound bar uses virtual surround sound processing to create a wraparound effect that draws you into the action. You'll love the way it brings the soundtracks of DVDs, Blu-ray movies and high-def TV shows to life. You won't even need a receiver or amplifier Ã¢ÂÂ this sound bar has built-in amplification to power its six drivers for clear dialogue and spacious, lifelike effects.
