Asking for a little VCad help

[eddantes]

When exporting SPL out of the Enclosure tool - which should one use: 2pi or 4pi (after adding the diffraction response).

Thank you.

PS - the export is what I use in the Merger tool as the "Low" part.

2pi is also known as half space or infinite baffle. It simulates a driver with a single plane stretching to infinity. Use this for designing in-wall speakers.

4pi is full space, the full radiation pattern with no boundaries. Use this for designing typical freestanding/cabinet speakers.

Ok. As I thought. So after simulating the cabinet, I add the diffraction curve, and export as 4pi to merge with the simulated diffraction of the driver FR. It's what I intuited but wasn't certain.
