The Basics of Wireless Subwoofers
If you’re not familiar with wireless subwoofers, let alone their specific operation, it can be a bit confusing.
To make things simple, there are several main components involved in a wireless subwoofer system: a receiver, subwoofer driver, and an amplifier. And each component has its own little subcomponent. But all you need to know is this: a wireless subwoofer system operates on its own frequency and lets you adjust its volume independently from your audio system.
This way you can add more sound to your room and to your entertainment without having to add physical speakers. So, wireless subwoofers are like small sound systems in themselves.
But even though they are technically little, there are a few downsides to wireless subwoofers you should know about. First, they can be expensive. Second, their limited range means that you can’t take them to the back yard or move them around the house as you wish. Thus, they are more suitable for indoor application than outside use.
The wireless subwoofers utilize either direct infrared or radio frequencies to transmit a signal. Radio frequencies are more prone to outside interference, so you may experience signal loss if the frequency is not properly set. On the other hand, infrared technology has been around for a long time and is considered more reliable.
Transmission Methods for Wireless Subwoofers
Modern audio systems usually use digital amplifiers to power multiple speakers in a speaker system. With the massive surge in wireless systems, there have also been considerable developments in wireless speaker systems. A big trend nowadays is to fit a powerful subwoofer into a wireless subwoofer. This is in part due to the advantages of wireless systems, which include easy installation, versatility, and freedom from wires.
Many new wireless subwoofers are powered by digital amplifiers that have a number of modes for transmission. The two most common modes of wireless subwoofer transmission are DTS and Bluetooth.
Gizmodo explains that the newer wireless subwoofer systems make use of the DTS codec, which aids in data transfer to a 5.1 receiver system. The DTS codec allows the wireless subwoofer to distribute frequencies between 20 Hz – 500 Hz and one of its particular advantages is that it means that sound quality is preserved while you are streaming music via Bluetooth.
Bluetooth is also a convenient way to stream music wirelessly. You can stream music directly from your smartphone or tablet or from any compatible source via Bluetooth. This makes perfect sense if you are looking for flexibility and convenience with your audio system.
Wireless subwoofers are typically referred to as subwoofers—or subs—due to their powerful bass output. They consist of a cabinet covered in a specialized woofer speaker, a built-in amplifier, and a radiofrequency transmitter.
The two most popular types of subwoofers—passive and powered—use two different co-axial driver components for the woofers, or speakers. Passive subwoofers have no built-in amplifier and are often used in conjunction with a powered subwoofer that is connected to an amplifier so that both the subwoofers can work together.
Subwoofers use the radiofrequency (RF) technology to amplify and modify sound. The input signal received by the transmitter is sent to the subwoofer. During amplification, the signal is strengthened and converted into mechanical energy. The mechanical energy is then transmitted to the subwoofer, where it is turned back into acoustical energy. Amplification happens with the aid of suitable components (e.g., amplifiers, filters, power supplies, and drivers) embedded in the subwoofer. The transmission of the power to the subwoofer is accomplished by co-axial cables or air conduction. The co-axial cables transfer the electrical energy to the drivers magnetically.
Infrared subwoofers are very efficient and this is because they do not create heat like conventional woofers do. Infrared subwoofers use a slot loaded design and they have no need for air vents or dustcaps. Since they do not produce heat, they do not need to be cooled and this makes them highly efficient.
These subwoofers come with an infrared LED light and a heat sensor. The heat sensor serves two important functions, the first is to supply power to the LED and the second is to detect the vibration. When the sensor detects vibration, the LED turns on and when the sensor doesn’t detect vibration, the LED turns off. When the LED is on, it supplies the surface of the cone with light causing it to produce sound. As soon as the LED turns off, the cone absorbs heat from its surroundings and this makes it go back to its original shape creating the pulsing sound.
Most wireless subwoofer models are bluetooth compatible and work similarly to other bluetooth speakers. Once you choose a subwoofer, you have to turn on your bluetooth connection on your phone and set it to “pair with device”. Then follow the instructions of how to pair the device and you will quickly be ready to play your music.
The great thing about these subwoofers is that you don’t have to connect your phone to the subwoofer via a wire. Instead, they connect wirelessly. It’s just a matter of downloading your favorite music onto your phone, pairing the device, and then enjoying your favorite music with the incredible tunes of a wireless subwoofer.
The Bluetooth® connection only carries the music signal from the phone to the subwoofer. The bluetooth signal has a limited distance. Depending on your phone/device, it can be around 33ft (10m), 20ft (6m), or even less. This means that you can usually play from your phone or tablet from the location of your bluetooth subwoofer.
Bluetooth technology has captured our lives by storm in the past few years. Even the most conservative people are getting Bluetooth headsets and speakers for their homes. It has become popular in homes, offices, and schools as well. This technology is spreading at such a great pace among the music lovers. You might be wondering how Bluetooth works exactly and why it is so popular among people. The answers to these questions lie in basic science. Let’s try to understand how Bluetooth works.
There are two types of Bluetooth devices such as transmitters and receivers. A Bluetooth transmitter is a device that wirelessly sends a signal to a receiver. Similarly, a Bluetooth receiver is a device that receives a signal from a transmitter.

Bluetooth transmissions are the same as radio transmissions. It works by allocating a specific amount of frequencies to the transmitter and receiver. Each device works on a particular frequency so that there is no interference between the devices. The device that is receiving the signal identifies it using the code. It is coded for data transmissions to identify the signals sent by the different transmitters. However, your music Bluetooth headset will work only with a Bluetooth receiver.

Disadvantages of Using Wireless Subwoofers
The simple answer as to how wireless subwoofers work is that they use radio signals to transmit the audio feed from your AV receiver to the subwoofer.
A dedicated transmitter is attached to your AV receiver and an antenna in the subwoofer receives and broadcasts the signal. A wireless subwoofer has no connecting wires between the two components with the exception of the power cord.
Your AV receiver sends the audio feed to the wireless transmitter and from there it is broadcast to the antenna in the subwoofer. The signal is then sent to the amplifier and the amplifier will create an electrical signal which is sent to the woofer, vibrating the air to create the sound.
The biggest advantages to wireless subwoofers are convenience, being able to place the subwoofer in any location as long as it has an outlet, and system flexibility. Instead of having to run wires to the subwoofer location, nowadays all you have to do is get an extension cord and plug in your subwoofer. This makes it really easy to hide your subwoofer behind home theater seating or other items that may be in the way of the subwoofer’s path.

The concept for a wireless subwoofer is actually quite simple. The device uses a transmitter to send the music’s bass signal wirelessly to a receiver. The receiver decodes the signal from the transmitter then uses a subwoofer to get the low notes out to the listening area through the use of an audio cable.
Wireless subwoofers basically do the same thing as a passive subwoofer (one with no built-in amplifier) except they are completely wireless and convenient.
