The computer speakers have really evolved in the last decades. Today they are featuring some really advanced technologies and they are capable of giving a powerful and realistic sound. There are all sorts of speakers today, in all sort of shapes, sizes and colors. But not all of them have to be used in your room, near your computer, and there are other types of speakers too.



For example there are the wireless speakers, and these are speakers that don’t have any wires. They are working with a transmitter that sends radio wave through the speakers. And as long as they are in the specified range from the transmitter, they will work and bring the sound from the computer or from any other kind of music player. You can use these speakers in your room, and place them anywhere you want because you will not be limited by the cables. But you can also take them in another room, and enjoy the sound there. And you can even go further and take them outside the house.



If you want some speakers to use them mostly outside the house, then you must choose some wireless outdoor speakers. These are specially build to last on difficult weather conditions, so they are weatherproof computer speakers. You can use them in the garden, or near the pool, or anywhere you want in your back yard. And you won’t have to worry about water splashing on them, or other weather conditions, because they will resist. Of course it is better to not expose them all the time to difficult weather conditions (so that they will last for longer), but if it’s really necessary you will be able to listen to some music while it’s raining or snowing.

There are many models of wireless outdoor speakers on the market, and some of them come in really interesting shapes. You can find speakers that are looking exactly like a rock, so they can fit much better into your garden. So now let’s discuss about some speakers of this type, and we’ll choose the Acoustic Research 900 Mhz wireless indoor / outdoor speaker AW 811.

The design is quite simple, but thanks to this design the sound will be spread in all the directions. It works with 900 MHz radio waves, and you can have the speaker at a distance of up to 300 feet away from the audio source (computer, other music players or even TV ). You can use this small speaker anywhere you want inside or outside the house – for example in the kitchen, bathroom, near the pool, or spa, in the garden and so on. The speaker is working with 8 C batteries or with an AC adapter. It may be possible that the speaker and the transmitter interfere with other 900 MHz devices around your house, and to avoid this you will have to tune the knobs on the transmitter and the speaker, until they sound good.
