Crossover Simulator

If anyone is interested, a partially-functional, beta, version of Crossover Simulator is now available. The current build is capable of simultaneously simulating multiple projects of up to 6-way parallel/series-type systems.

I'd like to finish it asap, but I can only work on it in between school work :D I hope you find it useful in your DIY projects :)

It's on the 4th line, just below the Crossover Simulator header, on the left menu. Here is the Download Link just in case :)

I am aware of the looping links. I will move those links down to the bottom of the pages and rename them to something like, "Click here to go back to the main page." It's just that I noticed visitors arriving from search engines directly link to my pages without seeing the main menu. This is a disadvantage of having frames, I think. Sorry about that.


Yes, it's possible to use mixed-order filters. You can use the sipmlest of all filters, or you may go all out super complex :) So far, I haven't encountered a passive filter that it cannot simulate.

I don't know of any other online transaction system besides PayPal. You got me curious, is PayPal not reliable?


(Did you want to donate? If so, out of around 113 downloads since XoverSim's release, you're about the only one to hint your intent to donate, I really appreciate it.)
Glad you like it, Raka.

Unfortunately, it's not that simple. Your FRD/ZMA files must come from your driver's actual measurements (to get accurate results). If you just want to investigate filter bahaviour with different FRD/ZMA datasets, you could use Subwoofer Simulator to write simulated FRD/ZMA files.

To make modeled FRD/ZMA files from SubSim, simply:

--> Set SubSim's upper frequency graph limit to about 20kHz or 30kHz
--> maximize SubSim to get more datapoints into the FRD files.
--> For your Woofer(s)
---- Enter your woofer's Thiele-Small data
---- Design your box (sealed, vented or what)
---- Write the FRD files
--> For your Tweeter(s)
---- Enter your tweeter's Thiele-Small data
---- Use the Sealed-Box model, set box volume to something very large -- something like 1e12.
---- Write the FRD file

Here is a screenshot of FRD/ZMA files made from Subwoofer Simulator.

Again, you really should use measured instead of modeled data. If you're comfortable with a soldering iron, try Speaker Workshop. It has a measurement function (and a filter simulator as well).
