Turbo Bass Express is a useful and precise utility that I developed to specifically design a cabinet to perform in the confines of a car boot tuned to cope with road noise and internal pressure. No other program I know of will perform this specific task.

All you need is a technical data sheet from the manufacturer of the mid range, woofer or sub woofer. You will only need 3 of the parameters to calculate the desired cabinet needed. Comprehensive instructions included.

Results are Forth-Order Butterworth.
