Active vs Passive Speakers: What Sets Them Apart

Speakers play an important role in an audio system because they convert audio signals into sound. As a result, many electronics companies offer different types of speakers, both active and passive. Both produce sound, but the sound quality of each differs. Here are the differences between the best active speakers and passive speakers.

Differences Between Active and Passive Speakers

1. Components

The most important component that sets an active speaker apart from a passive one is the amplifier. An active speaker has a built-in amplifier that works on electricity and battery power. A passive speaker, on the other hand, needs an additional amplifier component to function. Powered speakers can operate independently because of the complete set of components they contain.

This differs from a passive speaker, which needs an additional power supply to operate easily. To get a passive speaker working, you need an extra external amplifier. That makes the best active speakers more practical to use than passive ones.

2. Power

An active speaker is powered by its internal amplifier. The unit has to be charged before use. This makes things easier for users, since they do not have to keep supplying power while using an active speaker. For passive speakers, power comes from an external source that has to be connected first.

3. How It Works

An active speaker can directly convert the signal picked up by its amplifier into sound waves. However, because its performance depends on the amplifier inside it, an active speaker's ability to amplify sound is very weak over a fairly large radius.

The best active speakers can only amplify sound up to the capacity of their internal power supply. This differs from passive speakers, which can deliver the speaker's maximum output. That is because an additional amplifier of any capacity can be paired with the loudspeaker as long as its voltage matches.

4. Types

Common types of powered speakers include smartphone speakers, laptop speakers and mini sound systems. Active speakers do not need to be connected to external electrical power. Their power comes from a pre-charged battery or the internal amplifier. Passive speakers are found in large sound system networks and are generally used in home theater speakers, theaters and events.

Because the power a passive speaker needs is supplied by external electricity, its sound output depends on the amount of power it receives. That is what separates the best active speakers from passive speakers. Passive speakers are used more often than active ones in places that need large or extra-large sound.

These are the differences you will find between active and passive speakers. So before you decide, understand the strengths of each and your own needs so you can make good use of the speaker's capabilities. You should also compare the prices of the two types to see which fits your budget.
