In simple words, digital wireless speakers form an integral part of the home theater or audio system components and are in the network but without being wired to each other. The wireless speakers communicate with the audio or video player through radio signals (radio frequency i.e. RF) or via infra red. The opportunity to cut down on the clutter of wires either lying on the floor or passing through ducts on the walls & ceilings, offer the flexibility to move the wireless speakers anywhere around the room or rather within the prescribed range of the player / radio frequency transmitter attached to the output terminal of the audio / video player.
The technology behind the operation of digital wireless speakers is a main speaker unit which combines the loudspeaker with a radio frequency (RF) receiver and a radio frequency transmitter unit. The transmitter connects to the audio output of any audio device. Digital wireless speakers work just like a radio that receives a signal from a radio station, but over a much shorter distance in this case. They typically work in the 900 MHz or 2.4GHz range although transmissions at higher bandwidth such as 5.8 GHz are available. The infrared based wireless speakers systems require line of site between the transmitter and the receiver.
The hassle free installation or the flexibility to position the digital wireless speakers wherever required comes with its own share of disadvantage. While they work great with all sorts of digital media, there are complaints of there being interference that these devices garner from a number of other electrical appliances like mobile phones and microwaves, a disturbance that occurs more so in the 900 MHz and 2.4 GHz frequencies. However, the speakers that function at 5.8 GHz bandwidth offer a lot less disturbance owing to a fewer number of wireless devices operating on this wavelength at any given time. This may be credited to this wave-length being the new kid on the block, but the fact also exists that any device using this bandwidth will have considerably lower range than a similar device, set similar distances apart on a lower bandwidth.
These wireless speaker systems are great to use with media players like; video games, mp3 players and home theater systems. Another interesting use is with musical instruments. A wireless speaker system or speaker kit can add a lot of flexibility in the use of your musical instruments, video games and mp3 players. You can even send your digital audio to a remote set of rear speakers and not have to worry about wires – this is a great way to use wireless surround to create surround sound in your home entertainment area. Home theater systems have a much greater ease of installation with the use of digital wireless speakers.
With a super-store like Amazon offering a range that is unbeatable, it makes little sense to buy your speakers from anywhere else. The Sony AIRSA20PK iPod Dock and Digital Wireless speakers, part of the S-Air range. There are a number of deals that you would hate to miss! The Bose® SoundLink® wireless music system not only ships for free but also is sold at 10% off the sticker price. The Sharp DKAP8P i-Elegance Music System for ipod / iphone with a wireless remote control in black is another steal worth a look and so is the Boston Acoustics HIDS3W Powered System with Wireless Subwoofer and iPod Dock in white. All of the above systems can also be plugged into the standard audio-out found on many WiFi routers sold today like Apple’s Airport Express.
