They are commonly used in meeting and event venues, houses of worship, schools, and other places where sound amplification is required. 

PA speakers come in many shapes, sizes, and power ratings, and can be used in conjunction with other audio equipment such as amplifiers, mixers, and microphones. With the right PA speakers, you can deliver clear sound to your audience.

If you need a PA speaker, you should consider these things first. Depending on the characteristics of the indoor or outdoor space where the speakers will be placed or the number of people who will be listening to a speech or music, you should decide which type would perform and fit better.

 

Subsequently, you will choose a bigger or smaller speaker with bigger or smaller drivers and more or less wattage.

Active PA speakers, also called powered PA speakers or PA speaker systems, combine a power amp and power supply in one, and require less cabling because they don't need to be connected to an external amplifier or mixer to function properly. 

They usually have multiple inputs and outputs on the back panel, so you can connect different devices at the same time.

The benefit of active PA speakers is that they take up less space and are easier to transport because of the built-in amplifier. 

Still, there is a downside to this type of speaker: you can't use an external amplifier like you can with other types of speakers. 

Active PA speakers require their power source (battery or AC outlet) to function properly.

A subwoofer is a low-frequency speaker in a PA system that provides low-end sounds such as bass or drums. The benefit of having a subwoofer is that it makes music sound fuller and more powerful.

If you're playing music in a small room, or you need speakers to play someone's speech, you don't really need a subwoofer. If you're using PA speakers for a big event, you definitely need a subwoofer. 

We all know regular speakers can produce low-frequency sound, but they can't really cut it down like a subwoofer. To experience true full-range sound, a subwoofer is essential.

Microphones and stands can be essential for microphones and vocal performances. Additionally, you may want to consider cabling and connectors to get the best sound out of your PA speakers. 

If you plan on using your PA speakers outdoors, you may want to look into waterproof covers to protect your speakers from the elements. 

Finally, you may want to consider PA speaker stands, which can help to get the sound to the right level and position in the room. 

With the right accessories, you can make sure your PA speakers are set up and maintained properly for optimal performance.
