Wireless speakers for TV

So, you bought the big TV, bluray player, and home theater seating, and you’re ready to crank up the sound. But wait – is that all your TV can really produce? Although the latest TVs give superior resolution and image quality, the sound they produce can sometimes be described as satisfactory at best. Fortunately, there are plenty of ways you can beef up your systems sound, by upgrading to a nice set of speakers. And for added convenience, less clutter, and the ability to get your surround sound just right, wireless speakers for your TV are a great way to go.

Any variety of wireless speaker for television will have a few key components. First the transmitter, or base station. This is what connects to your television, amplifier, or other audio output and converts the signal to the speakers. Transmitters for wireless speakers can use one of two different technologies to transmit the audio signal.

First, radio transmission. This works just like a normal radio, sending the audio signal to a radio receiver in the speakers. The benefit of this is that range is generally fairly good, certainly more than you would ever need for a TV speaker! The disadvantage is that some other electronic devices can cause interference with the signal, leading to brief bursts of static or weird noise that can interrupt the sound. This does depend on the frequency of the radio signal, as radio transmission comes in many flavours. Common wireless speakers kits use a 900MHz band, whereas Bluetooth speakers for example use radio waves to connect, but a very weak high frequency signal compared to other wireless TV speaker technology. This makes them less likely to be interrupted by consumer electronics. Because of the low powered signal, Bluetooth speakers don’t have the range of some other wireless speakers, but they do have the significant benefit of being able to connect to a wide range of other devices without being tied to a specific transmitting device.

The other method of transmitting audio remotely is infrared. This is a poor second cousin to radio transmission for most applications, as the signal relies on line of sight – limiting range and leading to issues with interference.

It’s worth noting that the term ‘wireless speakers’ is something of a misnomer though. Any speakers will need power, and power means one of two things – batteries or power cables. Batteries work, and some speakers come with rechargeables built in, so you can simply plug into a docking station to recharge when not in use. A good solution but not always convenient. Battery power speakers will also, by nature, be less powerful than a powered speaker. This in effect means that a loud system is still going to have some cables involved. Strategic positioning of your speakers near existing power points is a great move, but if you just cant manage to make it work, an electrician can often install an extra socket for you relatively cheaply. So although wireless TV speakers might not be completely wireless after all, there are significant benefits to reducing the clutter of cables at least a little!
