What is a stereo subwoofer?

Stereo Subwoofer is another speaker that can be added to the music system. The advantage of using a stereo subwoofer is that it plays low -frequency sounds of bass between 20 and 125 Hertz/Hz. The subwoofer, which was first designed in 1966, is used for domestic kinematory experiences for home and automatic stereo systems. Subwoofers have a crossover filter that tends to be set to 100 Hz and plays all sounds at a frequency below 100 Hz, but not those above 100 Hz. There are a number of stereo subwoofer types depending on the settings, amplification, size and box style. The basket is the overall frame that holds other components in place but is separate from the box. The voice coil is a coil surrounded by a wire attached to the main cone. The shock absorber called the spider controls the movement of the cone. The magnetic energy of the coil is concentrated by a piece of pole, steel pole, flows through IT.

There are a number of boxes for subwoofers. Boxes contain a subwoofer and help increase sound efficiency. The box size is determined to be a goodOtou boxes. This means the size needed to create the best sound from the subwoofer. Some boxes are sealed, while others contain ports that release air for a more efficient sound. Others gain the effectiveness of inclusion of passive radiators, which either contain a flat membrane or speaker without a voice coil.

Other variants include the BandPass box and a double subwwoofer. Bandpass Box is a two -chamber box where the sound for the first time passes through a closed chamber to a ported chamber. This sound is designed for music such as rock, techno and heavy metal. Double-Subwwoofer places two voice coils side by side or towards each other to create a different sound. There is also free air stereo subwoofer, which has no Asubwoofer box is mounted on the board instead.

speakers include different types of amplification plus systems designed for houses and cars intended for cars.All systems are designed to work in conjunction with other speakers, because the stereo subwoofer is designed to play only low -frequency sounds. The passive stereo subwoofer requires an amplifier to be attached to it. It can be either a built -in stereo system amplifier or a separate mono amplifier connected to a subwoofer. The powered subwoofer contains a built -in amplifier that ensures that the speaker has enough strength to work.

The

Subwoofer Sound can be adjusted by balancing or phase control. The alignment allows you to change the subwoofer settings, such as changing the threshold of the crossover from 100 Hz to 80 Hz or blocking frequencies that are too low. Phase control uses either polarity switches or continuously variable circuits and allows users to control when the Subwoofer Kicks In Subwoofer.
