This set of Audio Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Multi-Way Speaker System (Woofer and Tweeters)”.
1. By using more than one speaker at a time we create a ‘multi-way speaker system’.
a) True
b) False
View Answer
Explanation: The human ear can hear range of tones, generally in the range of 20 Hz to 20,000 Hz. To faithfully reproduce such a wide range of tones, it is normal to use more than one speaker at a time, creating a multi way speaker system.
2. What is defined as the speaker which covers low audio frequencies?
a) Woofer
b) Squawker
c) Tweeter
d) Crossover network
View Answer
Explanation: The most common sort of crossover network is known as a passive 2-way crossover. This type of crossover is normally built into the speaker cabinet, with the outputs going to each of the speakers mounted in the cabinet. The speaker which covers low audio frequencies (20 Hz to 1000 Hz) is called a woofer.
3. What is defined as the speaker which covers high audio frequencies?
a) Tweeter
b) Squawker
c) Woofer
d) Crossover network
View Answer
Explanation: The speaker which covers high audio frequencies (1000 Hz to 20,000 Hz) is called a tweeter. There are two types of filter in a 2-way crossover network: a Low-Pass Filter and a High-Pass Filter. The output of the low-pass filter (LPF) goes to the speaker which is responsible to produce low frequency sounds; and the output of the high-pass filter (HPF) goes to the speaker that is responsible for reproducing high frequency sounds.
4. What is defined as the speaker which covers mid audio frequencies?
a) Woofer
b) Tweeter
c) Crossover network
d) Squawker
View Answer
Explanation: The speaker which covers mid audio frequencies (500 Hz to 5000 Hz) is called a squawker. The speaker which covers low audio frequencies (20 Hz to 1000 Hz) is called a woofer and the speaker which covers high audio frequencies (1000 Hz to 20,000 Hz) is called a tweeter.
5. What is called the combination of low-pass and high-pass filter?
a) Band-pass filter
b) Passive filter
c) All-pass filter
d) Band-stop filter
View Answer
Explanation: The additional filters in the crossover network are referred as band-pass filters. A band-pass filter is a combination of a low pass and high pass filter together. The filter which changes the phase relationship among different frequencies and passes all frequencies equally in gain is called an All-pass filter.
6. Which of the following system have a reserve power handling capacity?
a) Microphones
b) Loudspeakers
c) Multi-way speakers
d) Blue ray
View Answer
Explanation: The speakers in the multi-way systems consist of tweeter, squawker and woofer. A typical multi-way speaker system reduces modulation distortion. Thus, multi-way speaker systems have a reserve power handling capacity.
7. In multi-way speaker system a smooth overall response is not obtained.
a) True
b) False
View Answer
Explanation: The above statement is false. As the multi-way speaker system reduces intermodulation distortion and also provides flexibility of performance a smooth overall response is obtained in a multi-way speaker system.
8. Which control is required in multi-way speaker system that may be balanced one against the other to give the particular feeling of concert hall?
a) Volume
b) Video
c) Pitch
d) Frequency
View Answer
Explanation: The range of tones for human ear is generally from 20 Hz to 20,000 Hz. To reproduce wide range of sound it is normal to use more than one speaker at a time called as multi-way speaker system. They may be balanced one against the other by means of volume control to give that particular feeling of concert hall reality that most pleases the listener.
