Setting up home theater speakers can be quite a pain. This is especially true if you live in a home that doesn’t lend itself to running wires behind walls. The end result will be that you half speaker cable clutter in your room. Many people don’t find this option desirable and thus either do not install of home theater or use options such as sound bars in order to emulate rear speakers. However, there are some options which I will take a look at.
Most notably, I’m going to talk about products which will allow you to create wireless rear speakers such as speaker kits. These speaker kits eliminate the speaker cable by transmitting the audio signal using a radiofrequency wave. The transmitter is usually designed to interface directly with an audio output which you can find on your AV receiver. Most people use a wireless option only for hooking up rear speakers. However, if you opt for a new 7.1 even 9.1 surround sound system then you might want to consider using a wireless option for the site speakers as well. Also, there are some some kits available which allow you to place the subwoofer somewhere other than right next to the AV receiver.
Most wireless speaker kits transmit at 2.4 GHz frequency range. This frequency band is available without the user having to potions a license in order to operate the equipment. These frequency bands also called ISM frequency bands. However, the problem is that a lot of wireless devices such as routers and baby monitors with use these frequency bands because they are available. That means that there might be some congestion which can lead to audio dropouts. More modern wireless speaker kits have come up with ways to combat wireless interference. In particular, wireless kits which utilize digital audio transmission usually half a fairly sophisticated mechanism in order to cope with interference.
In most cases, any data packets which have been damaged during the transmission be retransmitted. Therefore, the integrity of the audio stream is usually quite good. However, keep in mind that all this retransmission will cause a delay depending on how much buffering each component has. Data buffering is necessary in order to be able to retransmit data packets which have been damaged.
If you are using a wireless option for your rear speakers then I recommend to delay the audio going to the rest of the speakers which are hardwired. This will keep all speakers in sync.
