    How to Design a Crossover from Scratch

    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:

    SPL Copy:
    SPL Copy - Speaker Frequency Response Automatic Trace Tool

    Here's a link to a playlist which contains all the videos in the series:


    I currently have 6 videos in the series, I hope you enjoy and learn something. Please let me know if there is something else you want to learn. I'll try to post it when I can.

        I've used the program a bit... its really nice to be able to verify that I was using it correctly. Very thorough series as this program has a steep learning curve for anyone *just* getting into loudspeaker design. Helping a lot of people out, including me. Thanks!

          You are Welcome. I am glad you guys are getting use out of it. I have almost completed this series. I may do one more video on Phase if people are interested. Unless there is something that people really want to learn that I have not gone over yet. Just let me know if there is

            Since some of you were getting some help from these. I did another video about Phase. This will help you design a crossover by keeping the speakers in phase tot ry to avoid cancellation waves. I hope you like it.
