There’s no free lunch with speakers. There are many choices to be made, and every one of them has advantages and disadvantages. It’s up to the designer to define the objectives and find the best path forward to meet it, but there will always be compromises. Most companies only market the advantages, and don't bother to mention the downside of their offering. A talented designer will try to maximize the benefits and minimize the impact of the cons.

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.
