PA speakers come in two main types: powered and unpowered. Powered speakers can simplify a PA system because they are easy to set up. In addition, they are ideal options for musicians or DJs who travel with their own equipment. Keep in mind that models, such as the EON 515 XT Active Speakers, that combine a powerful amplifier, tweeter, and subwoofer into one component provide a rich, full-bodied sound.
Unpowered speakers, such as the Eminence 15-inch subwoofer speakers or the EV Electro Voice Tapco 100, typically better suit large venues because they require their own power source, amplifier, and sometimes even cross overs. The former produces a deep bass sound at 35 Hz, while the latter features a 12-inch woofer and a 1.5-inch high-frequency titanium compression driver. These two features combine to create superior quality low and high frequencies for a full range of quality sound.
