The Sony HT-CT550W 40" 3D Sound Bar System might be exactly what you've been looking for. A 2.1 system is simple. Think of a regular two speaker stereo system. Add a center speaker and a wireless subwoofer and voila! You've got a 2.1 channel home theater that's easy to set up, easy on the pocketbook and a joy to use. It's a 2.1 channel system with only two main parts.
The left, center and right, speakers are all contained in a single sound bar that's just 40" (1016mm) wide. It will look great on your TV stand or with the included hardware you can attach it to select Sony HDTVs, either on a tabletop or on the wall. With a little bit of additional hardware (not included) you can even hang the CT550W by itself from the wall. It's got three HDMI inputs and an HDMI output.
The HDMI Repeater function allows you to connect multiple devices via HDMI cables and easily switch between them keeping the HDMI signal intact on its way to your TV. Audio Return Channel (ARC) allows audio to be sent from your compatible TV to the system on the same HDMI cable that's sending high definition video and audio to your TV. That can eliminate one more cable from your setup. The HDMI ports can also pass 3D signals from a 3D Blu-ray player or 3D gaming system through to a 3D compatible TV or projector.
So you can start out very modestly and go all the way to 3D without having to buy a new home theater. To enjoy 3D you'll want to be sure to use high-speed HDMI cables. With high-speed cables you can also enjoy 1080p (in addition to 720p and 1080i high definition) and Deep Color (more than a billion colors!) on compatible TV sets. BRAVIA Sync is Sony's brand name for HDMI CEC, the industry standard that allows you to control multiple HDMI-connected devices from a single remote control.
The subwoofer's Digital Media Port (DMP) allows you to connect an optional Sony adapter that enables you to plug in your iPod, Walkman or PC-based devices so you can enjoy your portable music through the system. If you want great sound but you want to keep it simple and affordable, you want the Sony HT-CT550W 2.1 Channel Home Theater System.
