The most powerful model in the series, the Devine Axeo 15A active full-range speaker doesn't just deliver up to 390 Watts of power, but high-quality sound and a flexible set of connection options. Designed for professional stages, this set of two speakers can form part of the sound system for live bands or mobile DJs, and can also be combined with one or two 18 inch woofers for even bigger sound and fuller bass. These 15 inch speakers can be directly connected to everything from DJ controllers to PA mixers, and from electronic drum kits to digital pianos and keyboards. Microphones can also be plugged straight in, while a built-in audio player supports playback from an SD card or USB stick and the integrated Bluetooth receiver supports wireless audio playback. Basically, with this stereo two-piece, your setup can be as simple or as extensive as it needs to be.
