BI/Dipole radiator configuration

[Quakeos]

My brain is hurting, literally.

Can someone please help me out crack this mystery..

This RBH Surround speaker is a Bipole-Dipole configuration, so the woofers are in phase but tweeters are out of phase.

Clearly, they would have to wire ONE but not both of the tweeters out of phase, which should cause a mad cancelation on one side on the speaker?

It states it uses a 12 db/octave crossover.

Any clue how this is done?

Thank you and happy new year.

That concept is based on misconception! Or poor understanding of how loudspeakers work in real life.

Yes. It is discontinued since 2015. This kind of "dipole" on-wall surrond speakers were introduded in the early days of multichannel movie sound (ProLogic). I can't find any similar speakers in their present models.

There is some point when used in a movie theatre but at home not really. But it really helps to create a diffuse "ambient" sound! For Dolby Digital 5.1 and so on specifications for speakers are different.
