With Dipole speakers, the two sets of drivers are out of phase with each other. What out of phase means is that while one set of drives is pushing out, the speakers on the other side are pulling in. If mounted properly in your room, the result is something called a null or dead zone of sound. See the graphic for reference. When properly set up, a Dipole speaker provides an open, enveloping surround soundstage. For this to work properly, the speakers must be positioned in-line with the listening position as shown. If you are sitting out of the null area, the effect can be spoiled. If you don’t want to, or simply can’t place your surround speakers and listening position as required, that’s where Dipoles come in handy.In a bipolar speaker configuration, the two sets of drivers are in phase with one another_both sides push air at the same time. The result is greater sound output where the dipolar speaker’s null would be. The optimum location for a bipole speaker is behind the listening position. This positioning offers the benefit of a more detailed surround sound and is the preference of people who prefer the greater localization of bipolar speakers when used in Dolby Digital 5.1, DTS.
