It takes just two front speakers to enjoy 3-dimensional surround sound-with Dolby Pro Logic 3D-Phonic from JVC, a radically new approach to home theater sound. Dialog is fixed on the TV screen as a virtual sound source, while the surround components are synthesized by a sophisticated digital signal processor, mixed with the front signals, and then played back by the two front speakers. You'll get the sensation of being in a movie house, overwhelmed by surround sound that seems to be coming from an array of speakers. Ease of installation is an additional advantage: you don't need to run cables for surround speakers across your living room floor. Just connect your main speakers as usual, sit back, and be prepared to be surrounded!
