With integrated HEOS technology, these speakers ensure a stable connection throughout the home, allowing for synchronized music playback in multiple rooms or individual audio selection per speaker. Each speaker measures 15.8 cm in height, 11.5 cm in width, and 12.1 cm in depth, weighing 1.4 kg. The Duo Pack can also function as rear speakers in a Denon HEOS home theater configuration, creating immersive surround sound with authentic audio positioning for movies and series when placed behind the seating area. Integrated streaming services like Spotify and Apple Music provide access to extensive online music libraries, while the USB port supports playback of MP3 files for offline listening. The speakers feature a 3.5 mm auxiliary input for connecting external audio sources and support high-resolution audio formats.
