So now you understand how speakers work, and the difference between stereo and home theater speakers. You’re committed to achieving the best possible movie sound, and you know you need a good center speaker with limited off-axis vertical response and two rear speakers to provide the reflecting sound. This is the start of your surround sound system. Next, you should get to know the other speakers you’ll need, and how to set them up to achieve the most accurate sound reproduction for your next home theater experience.
Possibly the most important element that a good home theater speaker system will achieve is total sound immersion. This is basically that experience of being in the film. You don’t want to have to crane your neck every time a loud, low thud occurs to see where it’s coming from. The speakers in front, behind, above and to your sides should blend seamlessly with your visual experience.
How do you get this smooth audio reproduction in your own home theater? First, be prepared for a bit of tweaking. The acoustics of every room vary, so your setup might need several trial and error attempts before it hits perfection. But when it does, you’ll realize what all the fuss is about.
Dialog is a driving audio force in many movies. You want your center speaker to be close enough to your flat panel display so that the dialog feels cemented to the actors in front of you. In a 5.1 surround sound recording, more likely than not the dialog is hard mixed, attached, to the center speaker. This is the driver of most dialog, and as such you need to experiment until it is positioned so that you can hear the dialog coming straight at you.
A 5.1 surround sound system is the standard for most DVDs and HDTV broadcasts. The ideal spot to sit is directly in front of your center speaker at 0 degrees – your ears level with the speaker’s drivers. You should place the front left and right speakers about 22 to 30 degrees on either side of the center speaker, as seen from this spot on your couch. Your left and right side speakers should be mounted two or more feet above ear level, if possible, and be angled between 90 and 110 degrees toward you. These are rough guidelines, and you should try listening to all types of audio (Dolby, DTS, SACD, etc.) that you will be listening to, in order to get the most out of your setup.
7.1 surround sound is truly a surround sound setup, as it uses the rear speakers that are so important in establishing your location. The two rear speakers should be placed about 135 to 150 degrees towards the center of the room (which should be directly in line with the center speaker’s drivers). The other aspects of the speaker setup are similar to 5.1. Keep in mind that your rear speakers should never be directly behind you, or a 180 degree angle, because our brains will sometimes process this sound to be coming from in front of us.
So now that you have the basics of the two most popular types of home theater setup, try it out! Listen for all the details in your favorite movie, and adjust your speakers based on what you hear. You are going to be the one listening to and enjoying all of the great movie sounds, so be sure that you are enjoying your audio experience to its fullest the next time you pop in your favorite disc.
