The Mitsubishi LT-46149 stands out for its ability to deliver thrilling pictures and sounds from a sleek, slender flat-panel HDTV. A slim panel beneath the screen conceals a 16-speaker array, which delivers surround sound effects for TV shows, movies and video games — without the need for rear speakers. Dolby® Digital processing and amplification for the speaker system are built in. For true full-range sound, simply connect the TV's subwoofer output to a powered sub.
