Passive, unpowered speakers
Passive speakers donÕt have an amplifier built-in, they are lighter than powered speakers and are ideal for permanent installations. Passive speakers are good for hanging or wall mounting because you donÕt have to run AC power to them, and all the adjustments are made in the outboard gear like: amplifier, compressor, and mixer. Passive speakers require for you to understand how to match your speakers to an amplifier. The back plate of the speakers is very simple with only 2 inputs, one is for the cable coming from the amp, and the other one is for linking or daisy chain to another speaker.
Powered speakers are also called active speakers, they have an amplifier built-in which means no need for an external amplifier, and you donÕt have to worry about matching the speakers to the amp. Powered speakers have a crossover built-in, EQ, and DSP (digital signal processing). Powered speakers are easy to setup, and are the number one choice for those who need an easy and fast way to setup a pa system, they required a little or no knowledge about amplifiers. Powered speakers are great choice for houses of worship, mobile DJÕs, hotels, and nonprofit organizations. You can plug a microphone, your phone or any other audio source directly to the speaker, and you are good to go.
