So, apparently there seems to be a bit of consensus around this being a 97dB sensitivity driver, but LspCAD 6 gives 89,1 in free space, which should equal 95,1dB, or around 2dB below the others, and that is probably not just an accuracy issue. LspCAD (LspCAD.exe) free download, latest version 6.50, LspCAD 6 is a program intended for the design of loudspeaker boxes and. Here are some simulation results at 2.828VRMS: I believe I have compensated correctly for measurement distance and half/free space (assuming point source).
Note that this is is only the latest build of LspCAD, you need to have.

And as there are tons of settings that affects the damping, I am not paying that much attention to the low end sensitivity, so my focus is on the passband. Download and unzip the file, drop the contents in the folder for LspCAD 6 in your PC. As especially LspCAD 6 is a fair bit more advanced than anything else, I think it is safe to assume this has to do with some settings I have not yet found. I am having an issue, I assume it might have to do with LspCAD 6, but I am not quite sure.īasically, I do not get the same relationship between the resonant low end and the passband in LspCAD 6 as I do with other simulation tools.
