Sometimes people just don’t like the look of all that speaker wire hanging around their home cinema. You have the option of pinning it to the molding, to make it inconspicuous, or you could drill holes in your walls and ceiling, and string it through that way, but the simplest way to avoid seeing those wires is to simply get a wireless home theater system.
Understanding these wireless systems is pretty simple. Your receiver sends out a signal, whether it’s through a wire, or through the air. Your speakers pick up this signal in order to produce sound. In a wireless home theater, the receiver sends these signals out via radio, or infrared waves, rather than the electric signal associated with wired systems. Wireless home theater speakers have an RF or infrared receiver built in that allows them to pick up these signals and convert them into sound. Because speakers normally get their power through the audio cable, wireless speakers are powered with batteries, or sometimes a wall plug. That may seem like a ridiculous notion, because you’re just replacing one cable with another, but it’s often much easier to plug a speaker into the wall wherever it stands, than it is to wire the room to get the audio wire from the receiver to the speaker.
You might assume that this wireless technology comes at the expense of sound quality. The great thing is that these speakers are the same high quality as you’d find in a wired system. Battery powered systems may not deliver the punch that you need, but a wall-powered system is sure to have the power to deliver the level of sound and clarity that you want. Not only do these systems come in simple stereo, but you can also find a high quality wireless home theater surround sound system for little more than it would cost for a wired system.
The best wireless home theater system is difficult to nail down because everyone’s requirements are different. Things to keep in mind when purchasing a wireless home theater are that, as stated above, battery powered systems will pack less of a punch, and of course need to have their batteries replaced at regular intervals. Another thing to keep in mind is that an infrared home theater system (as opposed to RF), will require a line-of-sight between the home cinema receiver and the speakers. This is because infrared is simply a spectrum of light that human’s can’t see, so similarly to the fact that you can’t see the beam of a flashlight that is being shone in another room, the speakers can’t see the infrared beam, unless they can see the receiver. Radio waves, with an RF home theater system, on the other hand, can bounce of walls and other objects and still be read by the speakers with the signal intact. Therefore, line-of-site is not required for an RF home cinema.
