An increasing number of vendors has started to offer wireless speakers for home theater systems or a separate wireless surround sound kit. Multi-channel audio is still a relatively new phenomenon. As such in older homes which are not pre-wired for rear speakers, not to mention 7.1 speakers, a wireless option seems like the logical conclusion. But how reliable are these wireless surround sound kits and do they really eliminate 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 surround sound application, such as a home theater setting, the audio from each speaker naturally should be in sync with the video and also with the audio of the other speakers. Some wireless surround sound kits, such as the product from Rocketfish, will introduce a significant delay to the signal. Therefore when choosing a wireless surround sound kit, it is important to look closely at how much latency the wireless unit will introduce. The Amphony product adds a little less than 1 ms delay which should be sufficiently low for pretty much any application.
One of the main issues with wireless devices of any sort is interference from other devices. As more and more consumer devices go wireless, the available frequency space becomes more and more limited. Especially the 900 MHz and 2.4 GHz bands are exceptionally crowded, due to WiFi hot spots, cell phones with Bluetooth etc. Picking a system that avoids these frequency bands may be the logical choice, such as systems working at 5.8 GHz.
In addition to connecting rear speakers in a home theater setting, another useful application of a wireless surround sound kit is setting up speakers wirelessly in another room in cases where installing speaker wire between different rooms presents a challenge or for setting up speakers in your backyard within minutes. The applications are endless.
