Time to talk sound, and Bose is always a good place to start. Its newest designs on the 3-2-1 series begin at $999. That series uses only two speakers to create surround sound by employing what Bose calls True Space Digital Sound Processing Circuitry. The 3-2-1 GSX, which retails for $1,499, also includes up to 200 hours of digital music storage.

Usually sound systems employ five to seven speakers and a subwoofer, so it's important to think in terms of layout if you choose to go with a more traditional system. Dolby suggests that front speakers, tweeters and high-frequency drivers be placed at seated ear level, while surround speakers should reside higher. As for these types of systems, Gateway's KAS-303 is well-reviewed across the Web, as are various offerings from Onkyo. Pay attention to the basics when shopping around as well, like whether the system supports HDMI, or if it includes a DVD player.

If you really want to spend some money, you can eschew the affordability and simplicity of the aforementioned "home theaters in a box" and customize with high-end sound systems, and install features like pivoting woofers and dipole speakers set to your own specifications. You'll have no difficulty finding experts willing to help you through this process.

You're on your way to that perfect home-viewing experience. But get started quickly, the Super Bowl is just over four months away. And don't forget to add that final personal touch that makes those who pass through your theater's doors recognize the name on the marquee.
