This high-tech home theatre system produces gorgeous DVD images, plus realistic surround sound for your favourite movies, TV shows, and music. It also incorporates wireless rear speaker technology for easier setup.

The 5-disc changer gives you extra-detailed video from your DVDs. If you've got an HDTV with an HDMI digital video input, the 'HDX900W can upconvert standard DVD signals to more closely match your high-def display. Even if your TV doesn't have a digital input, you can still get crisp DVD playback via one of the system's analog video connections.

Optional accessories let you add XM Radio (requires an XM Mini Tuner package and XM Radio subscription), and your iPod (requires Sony iPod dock). And if you've got a computer with a hard drive full of music in another room, Sony's optional PC music player gives you easy wireless access to these tunes.

You'll also get rich surround sound without running cables across your room. The 'HDX900W transmits digital audio signals through the air to a compact rear amplifier. Simply connect this amp to the right and left rear speakers to get enveloping sound with easier hookup and less clutter.

Sony's auto calibration feature lets this system set its own speaker distance and delay settings for surround sound that's tailored to your specific room. The front and rear speakers boast two drivers each, for rich, dynamic sound. All four of these speakers include floor stands for easy ear-level placement.
