Enjoy the threedimensional home theater experience with the Focal Sib Evo 5.1.2. This complete set includes 1 subwoofer and 2 Dolby Atmos speakers. With the Atmos effect, the sound is sent to your ears via the ceiling. This means the sound is all around you. The set of 5 speakers can be placed in a cabinet or on a tripod. If you want to mount the speakers on the wall, use the included mounting system. Both treble and bass tones are audible, thanks to the wide frequency range from 70 to 25,000Hz. You'll be even more immersed in your favorite movie or series because of the powerful bass tones of the subwoofer.
