4.3.4.2 Speaker Type Selection

On the Choose your Speaker Type page, choose the correct type according to the properties of your target speakers. There are three types of the speakers can be selected: closed box, ported box, passive radiator. For example, for a single speaker with a ported box, you can choose the Single Driver Ported Box as shown in Figure 4-7. Noted that sometimes passive radiator speaker cannot be modeled successfully, in this situation you can need to choose ported box to replace passive radiator speaker model.
