A traditional line array speaker with multiple drivers have comb filtering and lobing issues, thus leading to a non-uniform response. This not only effects listeners at off-axis but on-axis as well due to the reflected energy being highly colored.
The CBT technology avoids these phase misalignments and gives a very uniform response. The result is a loudspeaker with excellent sound everywhere and a speaker that is much easier to integrate into a living room.
The CBT technology can be applied in several ways with different dispersion characteristics. The most common type is a ground plane CBT with multiple monopole drivers in a circular arc.
