This guy is a lot of fun to watch and he explains crossovers in a way that newcomers to design work will easily understand. Kirby has a nice site at http://www.kmakits.com and I encourage you to check it out.
Edius 6 free download version. DATS is very fast when it comes to measuring T/S parameters. It’s not free but is totally worth it. From is you can get your .ZMA file that you’ll need for Xsim. Skip the first 2:00 of this video…it’s about installing the software on Windows 7

If VituixCAD had some canned passive filters, not sure I would need XSim much though. Zaph 5.2 TM build. Dayton C-Note build. Carmody S2000 build. Selah Integrity build. To use Passive Crossover Designer (or the Windows version, WinPCD) requires that you import the speaker frequency response as an.frd file or the impedance curve as a.zma file. The instructions for REW explain how to export your measurements as text files and state that the format is compatible with.frd and.zma files. This is a cool video. Xsim is awesomeand free!! Be ready to hit the pause button A LOT if you follow along as you design your crossover. This guy really knows how to use Xsim and moves quickly. But, he very nicely covers everything you need to know to design a crossover. XSim (XSim.exe). XSim is a free-form passive crossover designer and simulator. This application allows the users to create, design or replicate circuit boards. It calculates and displays graphs with the frequency, filter response, group delay and impendance of the created circuit design. With the changed component values in the premium crossover, two speakers with different crossover tunings are now compared. (Just to be clear: The audibility of the shown low-Q resonances is of course not directly comparable to a modified Encore crossover, it should only illustrate that tonal changes can be perceived well below the 3dB you.
These aren’t the greatest videos when it comes to showing all of the features of Omnimic. Specifically, I can’t find a video that show how to generate FRD files. It’s one of many features of this great product. And, you’ll have the other file you need for Xsim. Maybe that’ll go on my “to-do” list.

These are a good place to start. WinISD is FREE and pretty powerful. Download sql developer for mac os x.
Yes, this requires some space. And yes, if you are going to test speakers and derive FRD and ZMA files to use for crossover design, you’ll need some manner to mount the drivers to take readings. I’m about to build one to the IEC spec, so check back for a “How-To” guide coming soon.
No need to go nuts here. I bought one at Guitar Center for $30 and it works fine. You’re just looking for a telescoping variety that will hold your measurement mic still at various heights. Keep it simple.

This LCR meter can test any of your crossover components. I find it particularly useful if you need to unwind an inductor to reach a value that is not available for sale off-the-shelf. I use the DER DE-5000 although there is a new version of it.
You’re SPL meter is useful for several reasons. If you are testing drivers and speakers, it is an imperative. Dialing is you sound pressure levels to about 72db will yield excellent results. A must have IMHO.
