The whole point of the Tang Band 8" is to use them as full range speakers. They do measure with an up tilt in frequency response so probably best listened to flat against the wall instead of toed in.
Still, we all hear differently.
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.
