With the Onkyo SKS-HT648 the sound of movies, games, and music is given more depth. This 5.1 channel speaker set provides every medium-sized room with a powerful surround sound. Enjoy the effects coming from every corner of the room, while the subwoofer provides an exciting movie scene with strong sounds. The downward-facing bass reflex port distributes the bass evenly across the floor, so that everyone in the room experiences a film or song more intensely. The round back and the solid material of the speakers prevent unwanted vibrations. As a result, you can also enjoy clear and undistorted sound at a high volume.
