Dipole or bipole: That is the question.
If you are planning to use the IW-115SR in a 5.1, 7.1 or 9.1 Dolby True HD or DTS Master Audio-based home theater, we recommend setting the switch to Dipole mode. Dipole 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-localizable sound field. This is ideal for reproducing non-directional effects like rustling leaves or the general hustle-and-bustle of a crowded city street.
If you are setting up a Dolby Atmos or DTS-X home theater, set the IW-115SR 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.
Feel free to experiment with both switch positions. Since the magnetic attachment of the grille makes removal and reattachment quick and easy, you can easily go from Dipole to Bipole depending on your choice of program material or personal preference.
