Panasonic on Wednesday said it will soon release its first 2.1-channel Blu-ray Disc home theater system, the SC-BTX70. The upright system uses a proprietary Panasonic technology that can reproduce virtual 7.1-channel sound in Dolby's TrueHD and DTS-HD virtual 7.1 formats. The two speakers, made of bamboo, have a top-mounted design for better sound dispersion. The system is rated at 375W of power, with each speaker and the subwoofer getting 125W.
