Correct Answer - Option 1 : woofer
For High Fidelity (Hi-Fi) type audio systems, the response of the sound is split up into smaller sub – frequencies. This improves the overall efficiency and sound quality of the speaker.
The low-frequency units are called woofers and the high-frequency units are called tweeters.
- Subwoofer: 10 Hz to 100 Hz
- Bass: 20 Hz to 3 kHz
- Mid-range: 1 kHz to 10 kHz
- Tweeter: 3 kHz to 30 kHz
Extra Information:
- In multi-speaker Hi-Fi systems, there are separate woofer, mid-range, and tweeter speakers with an active or passive crossover network to accurately split and reproduce the audio signal by all sub – speakers.
- A mid-range speaker is a loudspeaker driver that reproduces sound in the frequency range from 250 to 2000 Hz, also known as a squawker.
- The squawker is the speaker of the special unit in the speaker.
- Generally, the medium-diameter cone speaker is used as the mid-range speaker, and the horn speaker with high efficiency and low transient distortion is used as the mid-range speaker.
- A booster was a motor-generator (MG) set used for voltage regulation in direct current (DC) electrical power circuits.
- Boosters were made in various configurations to suit different applications.
