How close to a real home theater experience can I get with a sound bar instead of surround sound? Depending on the equipment you have, very close indeed!

Question What's the best way to connect up a sound bar in a home theater? Answer The answer depends on the kind of sound bar you have. Stereo sound bars If you're just connecting components for stereo sound, use the red and white stereo RCA jacks. Many sound bars even include a stereo cable in the box. This makes it easy to connect the sound bar to your TV's stereo output for better television sound. If your TV doesn't have audio outputs, you can also use the outputs on your DVD player, cable box, satellite receiver, or other gear. Virtual surround sound models Sound bars with virtual surround sound generally offer digital audio inputs. This connection will deliver the best, most detailed sound and most convincing surround effects from DVD players and other components with digital audio outputs. Most virtual surround sound models offer one or more types of digital audio connections, including HDMI, as well as optical and coaxial digital audio. Passive sound bars Hooking up a passive sound bar to your receiver is also very straightforward — it basically connects just like any other speaker. These sound bars include positive and negative terminals for each of the audio channels they play — five for virtual surround models, three for LCR models (the other two channels connect to separate surround speakers). You'll just need to connect each pair of terminals to the corresponding outputs on your receiver. Speaker wire is usually included. Powered subwoofers Connecting a powered sub is simple. Sound bars with built-in amplifiers give you a dedicated subwoofer output. You'll just need to run a cable from the sound bar to the subwoofer. We recommend using a subwoofer cable instead of regular audio patch cables when making this connection since it's specifically designed to carry low bass frequencies. You won't need to make this connection if you choose a system that includes a wireless subwoofer, but you will still need to plug the sub into a wall outlet.

Question I want to keep my home theater simple, so I'm opting for a sound bar rather than surround sound. I thought I had all the questions answered, but I'm stumped on whether I want a sound bar with a built-in amp.   Answer Most models have built-in amplification. As a result, they don't require a separate home theater receiver -- you just connect your audio components, and you're all set. Some virtual surround and Left-Right-Center sound bars don't have built-in amplification. These are called passive sound bars and you need to connect them to a separate home theater receiver. Passive sound bars are a good option if you already have a home theater receiver you'd like to use. Plus, a separate receiver can provide cleaner power and more sophisticated audio processing, so you might enjoy higher-quality sound. So like every other question, the answer is it all depends.

Question I've decided to go with a sound bar for my home theater. All the photos I see show them directly under the TV. Are there any other options that make sense?   Answer Sure there are! Although sound bars are often pictured on the wall below a wall-mounted TV, many of them are shallow enough to fit on a TV stand in front of a television. If you plan on going this route, double check the sound bar's depth to make sure it will sit safely on your TV stand. If you do plan to wall-mount your sound bar, think about cable management. You'll need to run at least a signal cable, plus a power cable if the sound bar is amplified. If you don't intend to run your cables through the wall, you can just let them hang down, or use a cable-hiding raceway to cover them. But if you do want to hide the wires in the wall, here are some important things to consider: Try to avoid mounting your sound bar on an exterior wall, since these walls have extra bracing and insulation that can make running wire difficult. Follow local building and fire codes. In many cases, this means you'll need to get UL-rated A/V cable labeled CL2 or CL3. The Underwriters Laboratory (UL) looks at heat generated from current flowing through wire, how quickly the cable will catch and spread fire when exposed to flame, and the wire's susceptibility to damage from external stresses. Don't run the power cable inside the wall. If you want the power cable hidden, you'll need to hire a licensed electrician to install a recessed AC receptacle in the wall, in a location where it will be covered by your sound bar or TV, and not obstructed by the sound bar's mounting bracket. You and your electrician may also want to consider in-wall power protection units. Another option is to route the A/V cable in-wall, and use a small wire raceway on the outside of your wall for the power cord.

Question I like the looks of a sound bar rather than speakers, but wonder how much I'm giving up on sound. Answer Those sleek sound bar-style speakers you're talking about look good with a  flat-panel TV, and require minimal space and wiring. Most models even offer built-in amplification, which means the only other gear you'll need is a DVD or Blu-ray Disc player and a subwoofer for deep bass roar and rumble. Some of  models even include a subwoofer. In a nutshell, single-speaker sound bars can deliver room-filling sound without taking up much space. This may be the solution for you if: You have very limited room for speakers or other equipment. The sound bar solution requires fewer pieces of gear than any of the other options out there, and you can easily wall-mount the main speaker right below your TV. Very simple setup is key. You only need a couple of cables to hook up these systems, and chances are they come in the box. You won't have to run wires from one side of your room to the other, either. You want the cinematic thrill of surround sound but your room can't accommodate a full-fledged surround system. Some of the more deluxe models feature advanced designs and special digital processing to create a convincing, three-dimensional sound field. However, you don't necessarily have to give up good sound for that sleek look. While some sound bars only deliver stereo sound, others create virtual surround sound. Now, they can't give you the same precise, enveloping sound you'd get from a system with five or more speakers. But they can offer more engaging audio than your TV speakers and give you a more complete sound experience. They accomplish virtual surround sound by bouncing beams of sound off your walls, or with special processing that controls timing and volume to make sound effects seem like they're coming from different directions.
