Some of the home theatre systems offered by Teufel (not Dolby Atmos) come with special effect speakers, the so-called dipoles. Depending on the version, these effect speakers have a toggle switch, which can be found on the rear connection terminal of the boxes. Here you can decide whether you want to use the dipole as a direct radiator or dipole.
As a rule of thumb, if the effect speaker is not mounted on a wall, always switch the box to direct radiator mode. If mounted on a wall or if the effect speaker is very close (less than one meter) to the listening position, you can set the effect speakers to dipole mode.
