Besides the obvious need of the HDTV in the home theater system, there is one thing that the system can't do without, and that would be a good quality surround sound system. There wouldn't be much point in watching a movie or television in all the great high def picture without great sound to coordinate with it. With all of the fantastic video being delivered from the wonderful big screen you also want the same delivery for your ears.
The sound is so necessary to create a good experience with the movie, making it something more than an image on a screen. If you were watching a horror movie, imagine that viewing experience with the sound turned down, if you don't have the creepy music and sounds then there is nothing scary about the image. You are just sitting there watching a bunch of dumb kids being killed at camp, and that's no fun. The sound is necessary to set the mood and program you when to jump out of your seat due to being scared.

You are going to have to choose the right surround sound system for the room, just like the HDTV you purchased, you need to know how much power and sound you require. If the room is small then there is no point in getting something too powerful, but if the room is larger you will need to bump it up. Surround sound systems come in many varied styles and kinds but they are much simpler to connect than in the past. The wiring has been reduced and the hookup has been simplified, the manufacturers want the process to be uncomplicated and user friendly.
You can still buy a surround sound system the old fashioned way and pick out all the components and speakers separately, but for most people, that is unnecessary and more complicated than it needs to be. For most consumers, a so called "system in a box" will be all that they need. A boxed system will include all of the things that you need to get the job done.
It won't take very long after you open the box and you will be listening to the new surround sound system enjoying all it has to offer in the home theater setting. This only takes a averagely decent sound system and just a little while to make all the connections. Be sure to look at these systems as they will probably be all that you need.
