When the “Suggest” button is used BassBox Pro attempts to design a box with a maximally flat amplitude response. Its ability to do this will depend on the driver parameters. It does not try to achieve a particular speaker alignment. However, if the Qts of the driver happens to equal 0.4, the optimum vented box will resemble a B4 (4th-order Butterworth) alignment. As the value of the driver Qts drops below 0.4 the optimum vented box will begin to resemble a QB3 (quasi 3rd-order Butterworth) alignment. As the value of the driver Qts rises above 0.4, the optimum vented box will begin to resemble a C4 (4th-order Chebychev) alignment.
