What are active speakers?
Active speakers are speakers that are built into amplifiers. They are also called driven speakers because they have their own energy source. There is a huge range of active speakers designed for virtually any type of sound system. On the contrary, passive speakers are powered only by signals that create the sound they make. If passive speakers are only able to handle low -current input signals, too much energy from the source causes failure; If passive speakers are too large for the audio system, they will not produce enough sound when using. The built -in driven amplifier can take a weak incoming signal and amplify it itself. Another advantage is the size. Unlike passive speakers, which must be very large for mastering high input signals, active speakers can be designed to be much smaller in forming a comparable level of sound.
The very basic design of the active speaker consists ofE Power sources, amplifiers and woofer or tweeter to add real sound. Another common design is a preamplifier, which electronically processes the incoming signal before browsing the main speaker amplifier. More complicated patterns will include at least one speaker and one tweeter on the speaker and everyone can contain their own driven amplifier.
The selection process that active speaker is suitable for a specific purpose depends on the source and what the speakers will be used. Although driven speakers are more flexible than passive diversity, it is still possible to choose a set that is too weak and breaks when the input levels are too high. The specification between the source and the speakers must always be compared before purchasing and connecting to ensure compatibility.
Active speakers are not only multi -enabled than their passive counterparts from the viewingSka size. Much more freedom is also involved in their design. This is highly advantageous for people who want to use unique speakers as decoration in their house or workspace, rather than just boxes that carry sound.
The combination of passive and active speakers is called crossovers, but can still be considered as active speakers, as they still have to have its own energy source. A good example of a crossover speaker contains a passive tweeter with a powerful speaker, but the combinations are virtually unlimited. Other variations of active speakers are wireless speakers. They will certainly need their own energy source - batteries to be truly wireless - and amplifiers, because the incoming signal is transmitted through the waves of air.
