We recommend setting the switch to dipole mode when you are running a standard set-up . This dipole mode puts the two driver arrays out of acoustic and electric phase with each other so in the near field, their outputs cancel, resulting in a very non-locallizable sound field. This is ideal for reproducing non-directional sound effects.

When installing in a Dolby Atmos or DTS-X home theater, set the IW-155SR to Bipole mode (the speaker arrays in phase with each other) The positional audio in Dolby Atmos and other object based systems requires precise sound localization from the surround speaker. Bipole speakers deliver very definitive imaging and outperform Dipole speakers in these instances.

The front mounted switch makes it easy to change for personal preference as well.
