Speaker classification introduction
As a single speaker is incapable to provide the whole range of audio frequency so the loudspeaker consists of different driver units which are as follow –
1) Tweeter (for High-frequency range)
2) Mid-range driver (for Middle-frequency range)
3) Woofers (for Low-frequency range)
Types of speaker
The speakers can be classified in many different ways. On the basis of amplification, they can be classified as follow –
1) Passive Speaker
2) Active Speaker
Passive Speaker – The passive speaker does not have built-in power amplifier. So they need to connect to an external power amplifier for high power output. Most speakers that are commercially available are passive type due to their small size.
Active Speaker – This type of speaker has inbuilt power amplifier for high and low frequency. So they are also called as Powered Speakers. But they are bulky as compared to the passive one so they are less used commonly.
