In this post I’m going to reveal some facts about wireless speakers which you probably are not aware of. I would just spend a few minutes to read through the next sections because knowing these facts can help you great deal when shopping for a pair of cordless speakers.
Obviously the speakers are wireless which goes without saying. But what exactly does that mean? Well, the fact is that only a portion of speakers on the market are actually truly wireless. Let me explain what I mean by that. Wireless means that the speaker can operate without being attached to anything else by any wires. Obviously, regular speakers have to be attached by using his speaker cable. The speaker cable sends the audio from the power amplifier. Without the cable the speakers are unable to receive any music. Now, how do wireless speakers work? The main difference is that the audio is not coming in via speaker cable. Instead, it is being received wirelessly. That might seem like a great idea but, unfortunately, wireless speakers need an amplifier in order to generate enough energy to drive the internal woofer and tweeter. Without the amplifier, the speaker would be silent. Also, wireless speakers require power for the wireless receiver.
So where does the power come from? Typically wireless speakers are powered by a wallwart power adapter. This adapter converts the mains voltage to a DC voltage. Obviously, this wallwart has to be connected with the wireless speakers. Therefore, the speakers are not really wires because there’s still connected by a cable. However, some brands of wireless speakers have internal batteries. The power therefore comes from the batteries. By using batteries, the speaker can be set up anywhere and is truly wireless. The drawback, obviously, is that the speakers cannot get is loud is speakers powered by a wallwart because batteries of a limited capacity and also speakers powered by batteries can only run for limited amount of time. Once the batteries run out of power they will have to be recharged. If the speakers do not support recharging then you will have to swap batteries which can get quite expensive over time.
Another fact which many people don’t know about wireless speakers is that the range which is published on the marketing pages typically a lie. Why do I say that? Most of the time you will set up your speakers indoors. Most likely, the speakers will be in another room then your source. That means that the wireless signal has to go through wall. In that case you will discover that the actual range of the speakers is a lot less than the number published in specifications because the signal when it passes through the wall gets much weaker. So be aware of that and figure that the actual range might only be one third of the published range when shopping for speakers. Also, do a listening test of possible to make sure the speakers have good enough sound quality. Otherwise chances are you might be disappointed.
