That might be one way to do this with an Alpha15. I had messed around with underlapped XO frequencies in your worksheets a while back, but haven't looked into that recently.

Is there any way to export the baffle response as an FRD file, so I can import it into Speaker Workshop and combine that with the driver's response and check it against different target curves? I know I can save the images and use SPL-Trace, and I think one of your worksheets or documents (the U/H frame comparison maybe?) mentioned something about being able to export responses, but I haven't figured out how to do it with the OB worksheets.

Also, I'd like to keep the upper baffle (with the midrange and tweeter) at 12" for aesthetic and woodworking-challenged reasons - that's a size I can get cut at Home Depot easily. I'd modeled tapered and other shapes, and they do give better response, but I don't think I have the skills to build them

With the free MathCad Explorer program you cannot save work, print work (you can copy and paste), import results from a file, or export results to a file. You need a full blown copy of MathCad to use these features. To do what you want would probably be better handled by importing a driver's measurement files (impedance and SPL) into MathCad and then do the postprocessing to add baffle and crossover effects. I do this with my own designs (for sizing BSC components for example) but it takes some careful programming and enough engineering/math knowledge of acoustics and electrical crossover design to make it work well.

Thanks. I might be able to figure out how to add data to a worksheet, but doing the math to properly combine it with the baffle response curves is well beyond my skills.
