900mhz wireless speakers are a type of audio speakers that use the 900 MHz Radio frequency to transmit and receive audio signals wirelessly. The speakers have a wireless range of up to 150 feet, allowing for audio transmission through different obstacles such as walls, floors, and ceilings.

People use 900 MHz speakers because it offers them the ability to enjoy stereo sound wirelessly, with no line of sight limitation. Which means they can enjoy audio from their audio source, such as a PC, MP3 player, iPod, stereo, or home theater system, without the need for speaker wire or cables. The 900 MHz frequency band provides a reliable channel.

900 MHz speakers typically have Microphone, Transmitter, Amplifier, Speaker and integrated RF receiver. At first the microphone is used to capture sound and convert it into an electrical signal. Then the transmitter converts the electrical signal from the microphone into a radio signal and sends it to the speaker.

In the receiving section the receiver receives the radio signal and converts it back into an electrical signal. If needed the amplifier then amplifies the electrical signal from the receiver to drive the speaker.Finally the speaker converts the amplified electrical signal back into sound

This type of speakers usually have an integrated RF (Radio Frequency) receiver which allows them to receive signals from a corresponding RF transmitter. The RF receiver converts the incoming RF signal into an audio signal that can be played through the speaker’s driver(s).

Based on consumers requirements there are both ac powered and wireless speakers available on the market. But most of them nowadays are battery operated because of the flexibility.

What type of people use 900 MHz wireless speakers?

900 MHz wireless speakers are typically used by individuals who want a convenient and flexible audio solution without the hassle of physical cables or the limited range of traditional Bluetooth speakers. They are popular among people who want to listen to music or audio in different rooms of their home or office, or for outdoor use. They are also suitable for people who want to set up a multi-room audio system, as the speakers can be easily paired and synchronized to play the same audio in different rooms. Additionally, some people with hearing impairments or visual impairments may find 900 MHz speakers helpful, as they do not require a line of sight connection like infrared speakers and can be controlled remotely.

Can 900mhz wireless speakers be configured in a multi-channel ?

Yes, 900 MHz wireless speakers can be configured in a multi-channel setup, where multiple speakers can be paired to a single source device such as a stereo receiver or a home theater system to create a surround sound experience. This setup allows users to have greater control over the sound distribution in their home theater or entertainment system, providing a more immersive audio experience.

But for doing so the user must have a multi-channel system by having a built-in receiver that is capable of tuning into the designated channel assigned to that particular speaker. This allows multiple speakers to be set up in different locations, but still connected to the same audio source. The receiver in each speaker can receive the audio signal transmitted by a single transmitting device, such as a multi-channel audio mixer or a standalone transmitter, on the designated channel. In this way, multiple speakers can receive and play the same audio signal, or each speaker can be assigned to a different channel to play separate audio signals.

Despite having so much potential some users have reported that there are some issues with the quality of manufacturing of sounds that are built for low frequency sound emissions. As a result, the speakers are unable to create the high-quality sounds that a wired speaker with several woofers can.

What is Woofer ?

It is a type of speaker driver designed to produce low frequency sound, typically the bass and lower-midrange frequencies in music and sound reinforcement systems. Woofers are often used in conjunction with other types of drivers, such as tweeters, to form a complete loudspeaker system capable of reproducing the full range of audible frequencies.
