I would look at the distribution of speakers on the market... particularly high end ones. Say the most high acclaimed speakers over $50K or $100K. These are intended to be examples of the very best possible sounding speakers with as few a compromises as possible for cost. What are some examples? Magico, Sonus Faber, Wilson, B&W. Notice anything in common?
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.
Who is right, and who is wrong?
