The two distinctive types of PA speakers are the Powered- also known as active speakers and the Unpowered – also known as passive speakers. The Powered speakers have built-in amplifiers while the Unpowered has yet to be connected to an external amplifier. The sizes of PA speakers vary from 8” to 15” and they come in different outputs as well. The volume of the PA speakers will depend on how and where they are going to be used. As a rule, solo acoustic set will require only 115-120 dB and vocals with a band, need 120 dB+. On the other hand, a 125 dB is already enough to make a band audible.
