Part of the thrill of going to the movies is simply that – going to the cinema to experience the popcorn, the stadium-style seating, the darkened room, viewing the extra-large screen, and being immersed in sound.
But what about watching what you want to watch without waiting in line only to discover the film you had your heart set on has been sold out? Not to mention having to deal with the person next to you providing unwanted narration of every scene and the person sitting in front of you blocking your view. There’s got to be a better way. Enter home theater systems.
A home theater system can be used in just about any room in a house, apartment, office, dorm room, and even outside! Home theater systems provide that extra excitement over just watching a plain, old television. One could say the earliest home theater system was simply being able to rent a VHS or Betamax movie and watching it at home. The next step was big screen, rear projection CRT televisions along with those satellite dishes that could double as UFOs.
Most recently, DVDs viewed on flat-screen HDTVs brought home a similar experience to actually going to the movies – but not close enough. Modern home theater systems can include multi-disc DVD/CD and/or Blu-ray players, an AM/FM receiver, and two to eight speakers providing 7.1 surround sound. Now we’re talking!
WHAT ARE HOME THEATER SYSTEMS?
Several components make a home theater system complete and functional. A typical home-theater-in-a-box (HTiB) system that supports 5.1 channel surround sound consists of a receiver, a center speaker, one pair of left/right speakers, two satellite surround sound speakers, and a subwoofer. Notice there was no video display listed? That’s because you don’t have home theater without an HDTV to enjoy your favorite movie.
Audio/Video Receiver
The receiver is the anchor for your home theater system. Its duties include preamplifier, amplifier, and general control center where everything is plugged into. The receiver decodes surround sound tracks on any multichannel audio source, e.g., DVD and Blu-ray.
A receiver might also have AM/FM tuner, multi-disc DVD/CD changer, and a universal dock for your iPod®. This gives you a great new way to enjoy music and videos when you’re not watching movies. Just dock your iPod® into the cradle and you’re listening to music through your HTiB speakers. The dock not only allows you to use the HTiB’s remote to control your iPod®, it charges the battery all the while you’re jammin’ and watching videos.
The back of the A/V receiver will have composite and component video outputs and HDMI outputs (at least two), plus an optical digital input and analog auxiliary input.
Center-Channel Speaker
The center-channel speaker is the unsung hero of the home theater speaker system. When you watch a movie, the center channel delivers more than 50% of the soundtrack, including almost all of the dialogue, and several sound effects. Since its purpose is to keep sound anchored to the on-screen action, a good center channel speaker is crucial for a well-balanced home theater system.
The best place to locate your center-channel speaker is directly above or below your television screen which will then be lined up with the primary listening sweet spot (the center of your seating area).
Subwoofer
If you’ve ever wondered what the .1 means in Dolby 5.1 or 7.1, it represents the subwoofer. The subwoofer plays an important part in the surround sound effect by reproducing low-frequency sounds (25 to 180Hz range). When the thunderous boom from an on-screen lightening and rainstorm makes you check the window to see if it is raining outside – then the subwoofer has done its job.
The best place to locate your subwoofer is … it depends. Especially if you only have one subwoofer, the location can drastically change the sounds you hear. The closer you move the subwoofer to the wall, the stronger the bass output will become. But, you don’t want to move it so far from the wall it literally lands in the middle of the room. Overall, the best place to put your subwoofer is in the corner. But you might consider placing a second subwoofer on the opposite corner from the first one so everyone enjoys the earth-shaking noise.
Left/Right Speakers
The two front speakers (one left, one right) are for playing music and the realistic sound affects of movies such as an action scene involving a lot of noise. These speakers can be small enough to sit on a bookshelf or large enough to be on mounted on floor stands.
The best place to locate your left/right speakers is equidistance on either side of your television. They should be positioned at a 22 to 30-degree angle facing the same primary listening sweet spot (the center of your seating area).
Satellite Surround Sound Speakers
These speakers complement the front left/right speakers by working to immerse the listener in sound effects and music. You’ll experience the whipping of a helicopter’s blades overhead right in your living room.
The best place to locate your satellite surround sound speakers is slightly behind your listening sweet spot and equidistance from the left/right speakers. They should be positioned at a 90 to 110-degree angle facing the same seating area.
Cables
Use the cables that came with your HTiB or change over to an HDMI cable. If your HTiB didn’t come with cables, don’t scrimp when shopping for them since digital signals will get weakened or outright lost using wiring and connectors of lesser quality.
ROOM SIZE REQUIREMENTS
The room where you’re going to set up your home theater is the most important decision to make. Every other decision, such as the size of your television, depends on the square footage of your room (including height) and where you’ll be sitting in relation to the television.
The size and shape of your room can make or break your surround sound audio experience. But, wading through all the science involved in acoustics and the associated jargon can be daunting when it comes to deciding which room in your home to set up shop. Just follow the rule that home theater professionals follow: Choose a room with dimensions that cannot be divided evenly by the same number.
For example, if your living room’s dimensions are 11-feet wide by 13-feet long by 8-feet high, that’s a better spot than your basement’s TV room which measures 16-feet wide by 12-feet long by 8-feet high. The reason is because the dimensions for your basement’s TV room are all evenly divisible by 4. Why is this important? Rooms used for home theater that are too structurally square will experience an audio phenomenon called standing sound waves.
Standing sound waves are created by the distance walls are from one another. The sound waves from your speakers reflecting off the walls and other objects inside the room can cause places where sounds cancel each other out, or even amplify sounds (like bass sounds in a corner). The simple cure is to take the room’s dimensions into account when selecting your home theater location.
AMBIENT LIGHT
Turning out the lights to enhance your enjoyment of the movie takes you back to the movie theater itself – where there are no windows. Theaters turn out the lights when it’s showtime, so should you. Review your ambient lighting situation before deciding on a room for your home theater. General room lighting, including lamps, and outside sunlight shining through windows can diminish the home theater experience. If the room has a lot of windows, opt for blackout shades or curtains which would still allow you to bring in the light when the movie is over.
ENERGY STAR
Not all home theater systems are ENERGY STAR qualified so read the product packaging or literature provided with the unit you’re considering to ensure it conserves energy. An HDTV and HTiB combination can conserve 68 KWh/year in energy savings. You don’t want your energy bill to go up just because your home theater’s sights and sounds are through the roof!
FINAL THOUGHTS
The ability to simulate the viewing and sound experience of the cinema in the privacy of your very own home is something that can be done inexpensively with virtually any room in your house. To see an ocean of colors on your HDTV and to feel sounds moving from front to back and side to side will place you in the middle of the action.
Remember that not all of us can have a room in our home totally dedicated to home theater. Your living room can have a home theater setup but it is also a living room. Ensure the setup of your system is conducive to other uses of the room and that all your speakers are securely mounted and wiring is stowed as to not make them tripping hazards. Then when it’s time, put in that movie and escape to the far corners of the earth.
We offer several different configurations in our Home Theater Systems section. You’ll find the top brands such as Bose, Curtis, JVC, Klipsch, Onkyo, Panasonic, Samsung, Sony, and Yamaha.
