    I've got 4n & 8n .zma files, and 90dB .frd files. If I need lower SPL curves, I just add some series resistance (which WOULD alter the z data). Using an appropriate L-pad shuld let you target any SPL & Z
    I could, but that's a lot less convenient than having them readily accessible and configurable within the application itself.

      I just tested the latest version (1.0.0 Rev 3), worked fine. Looks like a never uploaded to my web site. That was almost two years ago, that was probably the change for v3. Thanks for mentioning it. I'll get that uploaded and update my web site, probably tomorrow.

      FYI to anyone not familiar with it, for target curves, it's built into WinPCD similarly to Jeff's PCD. And the SPL change adjustment does work in it.

        I've updated WinFilters. The target outptut file will now have the nominal SPL as set.

          Mentioned before, but the latest release of VituixCAD is really powerful and quite well streamlined. I'm really impressed that it's free. I haven't explored it fully but it seems to be a one-stop-shop for speaker design.
