The picture quality of today"s HDTVs may be fantastic. But frankly, the sound can be about as flat as the panel. Samsung"s HW-D450"s dynamic, full-bodied sound will dance pirouettes around your TV"s tiny speakers. This sound bar uses built-in Dolby Digital and DTS decoding along with 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 - this sound bar has built-in amplification to power its six drivers for clear dialogue and spacious, lifelike effects.
