How to Use Passive Crossover Designer by Jeff Bagby
That is WinPCD, the standalone program that Dave Ralph built up to work like PCD, but without series xovers. It doesn't quite do everything that PCD (Excel) does.

To add to Ben's (Wolf) post: Jeff Bagby's Excel based Passive Crossover Designer (PCD) hasn't been updated since 2010. There are possible issues if you use newer versions (2010 and on) of Excel, maybe others can chime in about that. David Ralph's WinPCD was written to provide the same functionality without needing Excel. As you've noticed the user interface is necessarily quite different. It doesn't have all the PCD features as Ben pointed out, but for the most part (series crossover designers excluded) it does everything that PCD does. I believe David also added some features, like directivity plots, that aren't in the original PCD.
If you're just getting started and don't have Excel you can legally download a trial version of Excel 2003 and use that to follow the videos. With that knowledge gained you should be able to use WinPCD.
May seem like a dumb question to you guys, but do we use the frd and zma of the raw driver, without accounting for the enclosure, to build the crossover or are we supposed to take the frd and zma measurements after the drivers take their respective places in the enclosure and build the crossover with those measurements?

I just added the 5th installment. I've already shown how to auto-populate a 2nd order crossover based off the frequency. Unfortunately, this only creates a Linkwitz-Riley, which is not always the best for the speakers you choose. In this video, I will go over the 4 different types of crossovers in this program (Bessel, Butterworth, Variable Q, Linkwitz-Riley), how to determine their component values. Each one of these crossovers will directly affect your final frequency response of the speaker you are building. So if the auto calculate does not get you your desired response, try a different 2nd order crossover.
Typically when you think of creating a crossover, you think you just want to cross it over at X hertz. However, did you know there are different types of cr...
I will be getting into the graphs more in depth as we go. I just got back from vacation, so i should have some more up soon. Is there anything specific you want to look at in the graphs?
Alright, I just finished the 6th part - Determining Box Size. This shows how to determine the box size for vented or sealed as well as determining the response by using Passive Crossover Designer or WinISD. Enjoy! https://www.youtube.com/watch?v=gizfbOBFBlM
