A new trend is the appearance of an increasing number of home theater systems with cordless speakers or a separate wireless surround sound kit. As multi-channel audio still is a fairly new phenomenon, older homes are not prewired for surround sound, especially with the most recent trend of 7.1 surround systems. As such a wireless option appears to seem like the logical choice. But are these wireless surround sound kits reliable enough for real-world applications and do they get rid of the dreaded cable clutter?
Some wireless surround sound kits, such as the LG or Rocketfish allow to connect 2 speakers to a wireless receiver unit. This eliminates the cables from the front to the back. However, still cables need to be run from the receiver to each speaker and as such the amount of cables is just reduced but not eliminated. Another wireless surround sound product from Amphony comes with separate receivers for each speaker which in comparison to the other products does reduce the cable clutter, albeit not eliminate cables completely.
When using a wireless option, probably the most important consideration is whether or not the audio quality is affected, i.e. does the audio pick up any noise or distortion during the transmission. A good rule of thumb when picking a wireless system is to use a system where the audio is transmitted in a digital format which will avoid noise common to analog systems. Further, the amplifier inside the wireless receiver unit should be of good quality and introduce minimal distortion. Finally, the size of the wireless unit is worth considering as this unit should be hidden from view.
In a home theater setting, the sound from all surround speakers should be in sync with the video and each other. Some wireless surround sound kits, such as the product from Rocketfish, will introduce a noticeable delay. As such you should look at how much of a delay or latency the wireless will introduce to the signal travelling to the wireless speakers. The product from Amphony introduces a delay of a little less than 1 ms which should be low enough for pretty much any application.
But how well do these wireless kits work in a real-world scenario? One of the biggest concerns should be interference from other wireless devices. In the US, wireless devices are restricted to a limited number of frequency bands. Especially the 900 MHz and 2

But how well do these wireless kits work in a real-world scenario? One of the biggest concerns should be interference from other wireless devices. In the US, wireless devices are restricted to a limited number of frequency bands. Especially the 900 MHz and 2.4 GHz frequency band are increasingly crowded by WiFi, Bluetooth and an array of other devices making interference more of a concern. Picking a system working at an alternate frequency band such as the 5.8 GHz band would naturally reduce the impact from competing devices.
While wireless speakers and wireless surround sound kits are suited for use in a home theater setting, their use is not limited to that application. In particular setting up speakers in another room often poses a challenge in terms of running speaker wires or using speakers outdoors. Just imagine being able to set up a speaker in your backyard in minutes. The possibilities are endless.
