The power capacity of a vented-box loudspeaker system is shown to be directly related to the system frequency response and to the volume of air that can be displaced by the system driver. The vent area must be made large enough to prevent noise generation or excessive losses; the required area is shown to be quantitatively related to enclosure tuning and to driver displacement volume. Mutual coupling between driver and vent is found to be of negligible importance in most cases. The basic performance characteristics of a vented-box system may be determined from knowledge of a number of fundamental system parameters. These parameters can be evaluated from relatively simple measurements. The vented-box system is shown to possess two important performance advantages compared with the closed-box system.
