What Are Active and Passive Speakers?
Active speakers have an amplifier built-in to the speaker directly. They therefore just need power to produce sound.
A passive speaker, by contrast, has no built-in amplifier, so needs both power and amplification from external sources in order to produce sound.
Lithe Audio Wireless Ceiling Speakers: Active and Passive
As an example, let’s look at our highly popular wireless ceiling speaker from Lithe Audio. The active units, like this Multi-Room WiFi ceiling speaker, have an amplifier built into the unit and, as a result, are more expensive than their passive ceiling speaker counterparts due to the extra hardware and engineering that have gone into the one unit.
While active speakers require a power supply to power the amplifier to drive the speaker, passive units have no internal amplifier and so do not need a power supply to produce sound. So long as the amplifier they are connected to is receiving power, passive speakers will produce sound just fine.
Can You Daisy Chain Active and Passive Speakers?
Passive speakers can be daisy-chained (wired), to active speakers to receive their power and amplification from the amp built into the active speaker. This is an efficient means of operating a dual-speaker setup.
This is why the active speaker is called the ‘master’ unit and the passive speaker the ‘slave’. Passive speakers essentially inherit all of their power from the active/master unit to which they are attached and have no means of producing sound by themselves. This also means that passive speakers, all other things being equal, will be cheaper than active speakers since they do without the internal amplifier.
Depending on the power of the amp itself, it may be able to power many passive speakers or just one. Typically, if an amp is built into an active speaker, it will tend towards being on the lower end of the power scale, meaning fewer passive speakers can be powered. For practical reasons, amps built into active speakers have size constraints. External amplifiers have no such constraint, meaning the amp can be larger and, as a result, more powerful.
With Lithe Audio wireless ceiling speakers, active and passive speakers come in pairs, meaning one actively powered speaker can power itself and a single passive partner using its built-in amplifier. If you want more than two speakers in a room, you’ll need to purchase multiple active/passive pairs of speakers.
