Crossover programs

[A Reef Scene]

Is there a good program that will help in crossover and speaker builbing? If It could be freeware that would be great. If not that is not a problem as long as it is not 300.00 or somthing.

I would recomment checking out FRD consortium (just google it). They have plenty of freeware programs and Excel spreadsheets to get you started. They also have tutorials that will help out.

If you need more advice on some of the programs that are on the site you should check out the DIY forum at HTGuide.com. Have fun!

I have looked at differnt programs and seen differnt desgins. Here is one

And here is the second

Question is which one is better? For two of the same crossovers thay are very differnt.

Because they are different designs.

After 20 years away from building speakers, I decided to get back into it, long story. I built a few spread sheets with my calcs before I stumble on tons of freeware. The differences you'll find between calcs will be minor for the standard crossover of the same order and original formula, math is math. What you will stumble onto are the variations of the same orders. These are normally the named versions ie a 3 way 4th order Butterworth will have a different end result than a 3 way 4th order Linkwitz-Riley and differing gains at the crossover points.

For freeware, I recently down loaded the speaker workshop. So far it looks like it might be something good to play with and could be a good tool. But I still have all my other gear for back checking, signal gen, Oscope freq counter and various meters. From what I have seen, this looks to be a very good start point program, saved me a lot of time as I was building virtually the same thing in Visual Basic. Plus they have a forum for help, does not appear to have high traffic but most of the questions are answered quickly.

I use WinISD pro for all of my projects. I have found that it is pretty accurate (box response), as far as the crossovers, it has a crossover program for 2 ways. I just model everything in there (too lazy to pick up a calculator) and cascade them. The key to any design is research. You have to know what your goal is, and then figure out how to get there, on paper. Then you can start soldering stuff together.
