This Samsung 5 Series HT-J5500/ZA Blu-ray home theater system includes 5 satellite speakers and a passive subwoofer. To build a complete 3D home theater system, you'll also need a 3D TV, 3D glasses designed for the TV and a high-speed HDMI cable.
This is a wonderful product! Samsung never disappoints! I looked at a few other options, however, opted to pay a lil more and go with this system because it is wireless. It's wonderful to watch NetFlix without having a wired connection! The apps you can get for this (Netflix, Pandora, etc) and the ability to connect wireless to the internet are huge! The sound quality is amazing! Again - Samsung never disappoints! There are many sound systems out there - I say spend a lil more and get this one that's wireless, it's so worth it!
