What is the "front focusing bipolar array" technology of DT speakers?

The technical principle of FFBP is to imitate the sound characteristics of natural objects-omnidirectional sound. By increasing the reflected sound from the environment, a larger sound field is constructed, and there is a balance between accurate positioning and spatial expansion, so that a more realistic sense of the scene can be obtained when listening. But also can use the space more effectively, expand the listening range and make the placement of speakers more flexible.
