Live Sound Engineering Tips
What’s the difference between Sub and Bass a question someone asked
So let’s add Low to the question
In live audio engineering, the terms "sub," "bass," and "low" refer to different aspects of the lower frequency range of sound that can be manipulated during a live performance or recording session.
Here's a breakdown of each term in my own way if you have another way feel free to share with us let’s learn from you
1. Sub (Subwoofer):
- The term "sub" typically refers to the subwoofer, which is a type of loudspeaker designed to reproduce very low bass frequencies, usually below about 80 Hz.
- Subwoofers are specifically built to handle the energy and air movement required to produce these low frequencies without distortion.
- In live sound settings, subwoofers are often used to enhance the impact of kick drums, bass guitars, and other low-frequency instruments, providing a physical sensation of bass that can be felt as well as heard.
2. Bass:
- "Bass" refers to the lower range of the frequency spectrum, generally from about 60 Hz to 250 Hz.
- This range includes the fundamental frequencies of many musical instruments and is crucial for the warmth and fullness of the overall sound.
- In live audio engineering, the bass frequencies are managed to ensure that the music has a solid foundation without becoming muddy or overwhelming.
3. Low (Low Frequencies):
- The term "low" is often used to describe the lower end of the audio frequency spectrum, encompassing both the bass and sub-bass ranges.
- Low frequencies require careful management in live sound, as they can easily become overpowering or cause feedback if not properly controlled.
- Equalizers, high-pass filters, and other sound processing tools are used to shape the low-frequency response of the audio system to achieve the desired balance and clarity.
