NOTE: We made this video to help beginners get a better understanding of speakers and audio. You might find this video redundant and useless if you already know the basics of audio. If this sounds like you, please move on and watch some of the more complex videos on this channel.

Are speakers AC or DC? If you have an old school passive speaker, you could say that the signal is AC related. But if you have an active speaker, your answer is going to be a bit more complex. In this video, you'll find out:

How to know if you have an active or passive speaker.
Acoustical energy and how it relates to output.
How do you power your active speaker?
External and internal power supplies.
Example of AC plug and DC plug and what they look like.
