A wireless subwoofer has a transmitter that sends a radio frequency to the speaker. This radio may experience interference from microwaves, cordless phones, and other wireless home technology. For best results the transmitter should be 30 feet (9.14 meters) or less from the speaker.

Subwoofers are available in many shapes and sizes. It is important to choose one that provides enough base tone to adequately fill a room. Larger subwoofers are more expensive than smaller versions, but provide a much deeper bass experience for movies and music.

Each wireless subwoofer includes a built-in powered amplifier. This power rating determines how much bass the speaker will put out. Larger speakers typically have bigger amplifiers, which play a louder, deeper bass tone.

One important consideration when choosing a wireless subwoofer is budget. Subwoofers can be an expensive audio addition and wireless versions are more expensive than standard subwoofers. It is good to shop around for different options include shapes, size, and exterior finish. This will help keep the cost down.

Wireless subwoofers are also available for outside listening. These speakers are enclosed in water-resistant cases, which makes them a great addition to a poolside deck. Outdoor subwoofers can also be connected to small radios, compact disc players, and iPodsĀ®.

There are many wireless speaker systems to choose from. Most of these systems include a subwoofer. A wireless system is connected to an audio receiver that transmits the music to all the speakers in the home. This provides quality sound without messy wires. A wireless subwoofer gives the music a deep bass that brings more depth into songs. The tone is so low that it can actually be felt in the furniture and walls of a room.

The subwoofer handles low frequency transmissions that standard speakers cannot play. This is accomplished through a special music filter that captures low-frequency sounds. The filter is built inside the speaker and blocks high frequency notes ensuring only deep sounds are played.

Subwoofers are available in many shapes and sizes but most systems only need one. Low notes are not played in stereo and a single speaker provides enough bass. Using multiple subwoofers may create too much bass that will detract from the music.

A wireless subwoofer is enclosed in either a box or a tube. The tube subwoofer is a round cylinder that can be easily hidden behind furniture and doors. This type of subwoofer provides a good bass tone, while blinding into the room decor.

@Vincenzo -- That is mostly true. I mean, if you are looking for Bluetooth technology in a wireless speaker, you probably want to buy an entire speaker set rather than just a subwoofer. Otherwise, you would be pairing your device with just a subwoofer and you probably don't want that.

On the other hand, a wireless subwoofer using WiFi can be mixed and matched with other speakers through a receiver. That's a more flexible arrangement than just a Bluetooth subwoofer.


When you are shopping for wireless subwoofers, you might want to look for one with Bluetooth technology so it can be paired with smartphones and other digital media players. That type of connectivity is becoming very common and is very desirable when buying any wireless components.
