September 8, 2005 It’s a small step for technology, as wireless household more running cables or tripping over speaker wires. Logitech has announced the world's first THX-certified 5.1 speaker system with digital wireless dual rear speakers. The new Logitech Z-5450 Digital speakers, ideal for use with the living room entertainment center or the office PC, provide flexibility in setting up an instant surround-sound system. Each of the independent rear speakers can be placed anywhere within 8.5 meters (28 feet) of the speaker system control center, requiring only a power outlet; no unsightly speaker wires running around the room, yet no compromise on quality. With THX-certification and 315 watts of power, these speakers help create a theater-quality movie watching experience and provide enough thump to help people feel like they're inside the game.
