How to Use Passive Crossover Designer by Jeff Bagby

[Altoid]

For years, I wanted to design my own speakers, but didn't understand the intricacies that went into it. For all I knew, you bought a 2500 hz crossover from parts express, picked a woofer and tweeter that looked cool and went at it. It wasn't until i really got into DIY speaker building that I understood how wrong I was. Thankfully, Jeff Bagby came up with a great free to use program that can help us all out. My goal here is to help the DIY community along by helping teach the program to the best of my abilities. If anyone has any suggestions or questions, let me know, I'll see if I can help. Since, I personally am a visual learner, I'm creating a video tutorial series on this program. The first one, I just completed which shows you how to import FRD and ZMA files, as well as where to locate them. And how to use SPL Copy, if all else fails. I also help troubleshoot if your frd files are not importing properly. Here are the programs you will need:

Here is the next one. This one helps explain the basics of what speakers may work well with each other and where you could potentially cross them over.

Okay Guys, we are on to the third part of this series. In this video, I show how to actually create the crossover in the program based off the earlier videos. Later I will go into greater detail in how to calculate the different types of crossovers, some things to watch out for on the graphs, and how to add notch filters (ie baffle step compensator), etc. But the next video will show you how to take the values you have and physically layout the crossover.

Until then: https://www.youtube.com/watch?v=BDlPswC5U8U

I finally finished Part 4. This one shows you how to assemble the crossover once you've designed it. It also gives you an idea of where to get the crossover parts and which ones you would typically buy. Enjoy!

May I suggest that you edit your original post to add each successive video release. Lest they get lost in a horde of posts (or PITA to find).

That is a great idea. I'll do that now.

Why does mine look like this and how do I fix it?

I've never seen a screen like that before. Are you using Excel? Or what program are you using to open it?
