There are obvious advantages to be had from a point source phase coherent design. That is why increasingly horn + subwoofer solutions are being favoured by designers. The subwoofer is by design omnidirectional. Complex multi speaker designs have a hard time being phase coherent
Single way or multiway
The founder and builder of the highly respected high-end speaker company Gauder Akustik, Dr. Gauder, says that using a full-range driver is very bad. He uses 3- to 4-way speakers with extremely complex 10th-order crossovers consisting of 58–60 components.
In contrast, some other well-known and equally respected speaker companies — such as Voxativ, Zu, Cube Audio, and Totem — use crossoverless designs.
