What’s a subwoofer?
Subwoofer in audio usually refers to a subwoofer. In many businesses or media, also known as subwoofers, in-car audio systems, Subwoofer is responsible for reproducing those deep low-frequency sounds. The frequency range of these audios extends from the upper limit of 150Hz or 100Hz to the lowest of about 25Hz. However, it should be noted that this is only bass, not sub-bass. In professional audio terminology, only frequencies below 20Hz can be called sub-bass or sub-bass. This part of the audio is lower than the normal listening range of the human ear.
The working principle of the Subwoofer is to divide the sound into different frequency bands through the internal power amplifier circuit and frequency divider. The mid-and high-frequency sounds will be output to the satellite speakers, while the low-frequency sounds will be output to the Subwoofer. Generally speaking, a Subwoofer can emit low-frequency sound of 20-200HZ. When the energy of this kind of low-frequency sound is not strong, it is difficult for people to hear it, and it is difficult to distinguish the specific location of the sound source. When these low-frequency sounds are transmitted through the port, they will resonate with the satellite speakers, making the bass effect more shocking. People will feel that the bass is emitted from the satellite speakers, but in fact, the satellite speakers only enhance the bass effect.
For car audio, the playback frequency band is usually from the upper limit of 150Hz or 100Hz to the lower limit of about 25Hz, which is just bass, not a subwoofer. Technically speaking, frequencies below 20Hz are bass that exceed the musical range that the human ear can hear. From a scientific or professional exclamation point of view, only frequencies below 20Hz can be called subwoofers. The principle is: the internal power amplifier circuit divides the sound into several frequency bands through a frequency divider, the medium and high frequency bands are output to the satellite speakers, and the low frequency bands are output to the subwoofer. Subwoofers generally emit low-frequency sounds of 20-200HZ. When the energy is not very strong, it is difficult for people to hear and distinguish the direction of the sound source. Such low-frequency sound is transmitted through the port, resonates with the satellite speakers, and is combined with the weak bass produced by the subwoofer and satellite speakers. The satellite speakers will replay the speakers to release the bass, so the bass effect is very shocking and makes people feel the same as the satellite speakers.
What’s a woofer?
In audio, a woofer refers to a woofer. It is an important part of the sound system and is mainly responsible for playing bass frequencies, usually ranging from 20Hz to 200Hz. A woofer is a component in an audio system that produces low-frequency sounds, as opposed to a tweeter, which is responsible for producing high-frequency sounds. The woofer is usually located at the bottom of the sound system, while the tweeter is located above or on the side to reduce the impact of low frequencies on high frequencies.
What id difference between a subwoofer and woofer?
There is essentially no difference between subwoofer and woofer, there is no difference in their systems, both are used to output low frequency sound, the subwoofer is designed to reproduce the frequency band below the 30Hz level, while the woofer produces the frequency band above that sound. Their main difference lies in their scope of work and purpose.
Woofer is usually designed to produce medium to low frequency sound, and its operating range is generally around 20Hz to 2KHz.
Subwoofer is specially used to produce very low-frequency sound, usually below 20Hz, which can enhance the low-frequency effect and can also be used with other speaker systems.
