How does this wireless speaker work

Operate loudspeakers via radio? It actually works!

Thanks to our mobile devices, you quickly get used to the luxury of listening to your favorite music anywhere, anytime and anywhere. Whether on the go, via the integrated loudspeaker or headphones, just a few clicks separate us from our very personal playlist and a little musical break in the stressful everyday life. Anyone who has got used to this digital convenience on the go thinks often enough about their music playback at home. Until now, music fans usually had to set up a stereo system with powerful, wired speakers in order to be able to enjoy a real sound result without headphones. However, if the stereo system with the speakers was in the living room, listening to music in the whole house was only possible through additional wired speakers. Not at all practical and certainly not nice if you couldn't really make the many cables "disappear" and they also led to a real tripping hazard in the household. Wireless loudspeakers are a real alternative to this. Using radio technology, all elements of a loudspeaker system can be freely positioned in the room or even in neighboring rooms - sound enjoyment throughout the house.

 

What exactly are wireless speakers?

A central radio unit or a transmitter station is required for the commissioning of radio loudspeakers. It is usually connected near the stereo system and controls several loudspeakers from there via radio signals. With wireless loudspeakers, the music signals are transmitted as an analog signal on a specified frequency. Most wireless loudspeakers usually cover a frequency range of 20 to 20,000 Hertz. The specified wattage does not represent a purchase criterion. The watt information is not a power specification for the loudspeakers, but rather shows their resilience. Even with low wattage, large living rooms and entire apartments can be covered by radio. In practical terms, this means that an average of 10 watts of power is converted when listening is felt to be very loud!

Even if the music is transmitted exclusively via radio and not via cable, as was previously the case, wireless loudspeakers cannot do without cables. Because the transmitting station is connected to the audio source via a jack cable. When you're not running on batteries or rechargeable batteries, there is a second cable, namely the power cable. But apart from these two cable connections, the wireless speakers are a real alternative to conventional wired speakers. Because every additional box can be started up or the living room box can be taken into the garden without any problems, depending on the range of the system. The sound quality is also adequately taken care of: wireless speakers of high quality in terms of price and technology can even reproduce a much more precise and clearer sound than their wired predecessors.

 

Noise-free playback even at long ranges? Is that possible?

Yes and no. Because two factors play an important role in the range: on the one hand, your individual needs and, on the other hand, certain framework conditions. In general, the range varies from product to product on a scale of 30 to 100 m. Unfortunately, it often only becomes clear when the device is started up whether the playback is free of interference and noise. Because it can happen that you often have problems or interference with the sound transmission despite a high-quality product. This does not automatically mean that your new speaker system is faulty. The disturbances can have a completely different background. If other users are also working in the same frequency range as you, sonic overlaps are not an isolated case. Then the quality suffers in all systems. Ideally, you can ask your neighbors whether they use radio systems before buying - and then make sure when buying that your system does not overlap with the transmission frequencies of the neighbor.

 

How do wireless speakers differ from Bluetooth and WLAN boxes?

The main difference besides the range and bandwidth lies in the data transmission. With Bluetooth speakers, direct transmission from the player (e.g. smartphone, laptop or tablet) to the speakers is possible - without going through a router or transmitter. Bluetooth technology is manufacturer-independent and is supported by many devices. The greatest disadvantages of Bluetooth technology include a short range, around 10 m, and the often inadequate ability to control more than one loudspeaker. Wireless loudspeakers play music through the support of a transmitter station (see above). WLAN speakers need a WLAN network to enable music playback from the home network or the Internet. Using a previously installed app, WLAN speakers can even be controlled via tablet or smartphone and even enable a multiroom speaker system to be set up for listening to music in different rooms. This is only possible to a limited extent with wireless loudspeakers and only if the loudspeakers have an integrated interface for communication with mobile devices.

 

Is it all a question of price?

Wireless loudspeakers are offered by many manufacturers in different price ranges. Depending on the scope of delivery, the prices vary from less than 100 euros to several hundred euros. Unfortunately, cheap products do not convince in terms of sound quality. The higher price is not only due to the well-known brand name, high-quality, high-quality technical components also have their price. It doesn't have to be the most expensive speakers right away, if you value good sound, you should invest at least in the mid-range. Otherwise, the wired systems easily overtake your radio speakers in terms of sound.
