This is an automatic translation by software: One of the technological highlights of the series. This is, of course, due to the Dolby Atmos module integrated into the top panel. This coaxial speaker, specially developed according to Dolby guidelines, consists of a 100 mm mid-bass driver and a 20 mm dome tweeter. By radiating upwards, the Atmos signals reach the listeners via reflections off the ceiling. This eliminates the need for additional speakers. The traditional hi-fi section of the S 80 features two 170 mm woofers, a 110 mm midrange driver, and a 28 mm dome tweeter. This is sufficient for a frequency spectrum of 26 to 38,000 Hz. With the Atmos module, it's also an impressive 26 to 28,000 Hz.
