About Powered Speakers at Sound Productions

Get all the features you need right out of the box with powered speakers from Sound Productions! All speakers need a sort of amplifier to function. Powered speakers (also known as active speakers or self-powered speakers) have built-in amplifiers, so they’re ready to connect to your audio source without any other required accessories—making them great for environments where space is limited.

Powered speakers are typically the go-to choice for portable use because they’re affordable, easy to set up, and simple to use as standalone sound systems. They’re great for achieving an immersive audio experience with the minimal amount of hassle—perfect for delivering a polished performance in smaller venues that may not have their own sound system installed. With fewer components to pack, they’re also a great choice for traveling events, such as mobile DJ performances or adding music to an outdoor event. Many models include other built-in features such as effects, compressors, and more to make one powered speaker virtually a standalone PA system!
