The Focal Sib Evo 2.0 is a set of 2 satellite speakers. You connect them to your television or sound system. If you expand the Sib Evo series with more speakers or a subwoofer, they form a part of your surround set. With the frequency range of 70 to 25,000Hz, you can hear both bass and treble. That results in a lively sound, giving you a movie experience in your living room. Place the Sib Evo 2.0 in a cabinet, on a tripod, or hang them on the wall using the included mounting system.
