Open Baffle Analysis

I would like to determine the step frequency of a rear-open baffle speaker. The driver is mounted in a 10"h x 10"w x 12"D enclosure with an open back. Then, I'd like to invoke a sensitivity analysis by changing cabinet dimensions. I'm not sure if it's possible in modeling software, but I would like to compare results against an open driver with no enclosure. The purpose is to demonstrate (via modeling) the effect of a baffle on low-end frequency response. Then, conduct an actual demonstration with an audience.

Basta! offers a pretty simple way to model a driver on a flat baffle. It takes account of the driver's T-S parameters, the baffle size and shape, and any passive or active crossover you want to add.

If you want to model an open-back box (i.e. a U-frame), Basta! can model both the effect of the box cavity and the dipole roll-off, but not at the same time. See here: https://www.diyaudio.com/community/...baffle-and-other-woofers.426580/#post-8004549
