Why does BassBox Lite suggest different closed box sizes than other programs?
BassBox Lite tends to recommend a smaller closed box volume than less sophisticated programs. This is because the BassBox Lite closed box model allows several box parameters to be adjusted which are not adjustable in many other programs. These parameters include QL, Qa and gamma. QL is the Q of the leakage losses of the box. Qa is the Q of the absorption losses of the box. Gamma is the ratio of heat at constant pressure to that at constant temperature for the air inside the box. QL can be manually adjusted on the Box tab of the Design Properties window. It usually gets smaller as the box gets larger. Qa and gamma are automatically set according to the Damping or “Fill” setting of the Damp tab of the Design Properties window. The default values for Qa and gamma for different Fill settings can be adjusted with the Preferences window. BassBox Lite can be made to predict similar box volumes as other programs by turning on the “Use Classical equations” option on the Damp tab of the Design P
