3 popular types of DJ speakers are explained here; powered DJ speakers. They are also known as active speakers. These speakers require a separate amplifier. These include the subwoofers, the main speakers, and the monitor speakers.
One of the things that all DJs need are speakers. Speakers for practicing, perhaps speakers for producing, possibly speakers for performing and, definitely, speakers for listening to and discovering music. The best computer speakers are the “2.1” models. The “2” refers to the left and right stereo pair, and the “1” refers to the single bass speaker, which is normally found on the floor to give “intensity” to the sound.
There are some standalone speaker systems called “mini-array” speakers (the Bose L1 is one of the most famous), but most are still speaker-shaped cabinets, with holes in the bases so that you can place them on sturdy tripod stands, as you should. Most systems also offer at least the option of a subwoofer, making this type of configuration the “adult version” of the 2.1-inch computer speakers we talked about earlier. You can definitely add the subwoofer when you can; in public it makes a big difference. You may eventually want to add two.
