    In Passive Crossover Designer there is a grey button below the woofer and tweeter sections that says "View PCD Circuit Layouts". If you click it, it will unhide a tab called Printout (you can actually see the grey tab in rpb's image in post #114). This shows a generic layout for the woofer and tweeter with inductors (L1, L2, L3,...), capacitors (C1, C2...) and resistors (R1,...) labeled. If you hover the mouse over the cells in the woofer and tweeter areas a comment box will will pop-up showing what position that cell refers to. You should be able to look at rpb's values in certain cells and match them up to the generic circuit layout.

    I don't have time to do it now, but if it is too complicated I'm sure someone will take the time to sketch it out; it may just take a little bit for someone to have time to do it.

      The layout is pretty much like the one in post 48, and 56. Here's the PCD layout. Some of the x-over locations are labeled on my sim. The notches are not, since there are three potential positions. (All three are on the far right side.)

        Wow, that's a big xover. I'll put those values into my software and see if I get similar results

          There's a spot for many parts, and different layouts. Most are unused in our sim. The funny thing is, after you use the software a while, you seldom need to look at this layout.

          I need to post the modified files for the 9 x 14 baffle. Let me see if I can find them.

                Does this look like what you have?

                  Yes. That's correct.

                  • Note that some resistors are not real resistors, and are coil DCR or a combination of DCR and real resistor.

                      Correct, and the resistor values can be changed to tweak different frequencies by a few dB in the area of the notches. Buy extra parts for tweaking if you don't have some already. Also, assemble the x-over external, so that you can touch resistors, and see if they get warm at all under high spl conditions.

                      • And if you have some of those cheap alligator jumpers you can easily switch between crossover components and see what kind of difference that makes.

                          Thx everyone, I'm away on a camping trip (ugh) right now but when I get back I'm going to start building the cabs. Do you think this general xo design, barring any tweaks, is my best bet? If so, I'll start pulling together the parts. Thx again!!
