Hopefully it's there now!


I think it "timed-out" and vacated the premises ( since I take so long to create a post ).

Hi Bill,

Thank you.

I wish there is a feature in which one can input a real world sound clip waveform and simulate with the given xovers and drivers to see how the output would compare to the input. To me, although the step and impulse responses are very helpful, they are a bit theoretical and it's hard to translate them into real world affects of the real world sound.

Not 100% shure but will mean that should be doable for the design axis curve used in Xsim

1. In Xsim export each seperate bandpass as frd file.
2. Import each bandpass frd file per a dedicated transducer driver over in free VituixCad and let them sum with direct parallel wires without any XO parts. Should probably work without using active power amp in XO tab, else add one of those per transducer and if you need to delay any bandpass it can be set per power amp.
3. SPL chart should now look as Xsim did, then push "View" menu and then "Impulse response", fill in settings so rate is same as your audio test tracks will be and export this new IR convolution file.
4. Use a player as Jriver or Foobar to load the IR convolution file and tick it on and off to hear the difference while test track is playing, probably its best procedure to use head phones for listening test because they normal XO-less and then stay clear off add more XO point excess phase on top of what XO summing excess phase is within the convolution file.

Thank you. Sounds very intriguing. I'll sure to give it a try.

If I give someone all the specs to the drivers and box size and ports. Could someone make up a crossover design for me?
I have all the specs for the Dayton 8 woofers and seas tweeter and box size and ports being used. I have a 2way Electronic crossover for it that the person built for these but Id rather use passive crossover

I am building Marten King's open baffel a 2 way using the FF85WK a 8 ohm driver with a RE of 7.2 . with a high pass xover using a 25uf cap and 4mh inductor. I need to know if this would work with an amp with a 4 ohm output impedience. I downloaded the XSim program but can't find the files needed to plug into it. Do one of you experts have a down and dirty way to find out how much that 4 ohm output resistance would affect the xover point and slope ?

Carl and woody, you can get great help here to use this magnificent software, however first there are a few things you need to do.



As I understand speaker crossover design you need to get your drivers in your enclosures and measure the individual driver frequency response and impedance. You also need to measure the combined frequency response of your drivers.


Once you have your zma and frd files the crossover magic can begin!

Thanks for the reply but I don't have any tools to measure the drivers. And I realy thought the FF85wk being a fairly popular driver someone should have the files for it.

I have a Dayton mic. Do I use REW to get the specs? I also have one of those Dayton audio driver tester units

Woody,

go over to multy-way forum and someone might help you. There is free excel spreadsheets (response modeler can simulate OB) and a tracing software to work with manufacturer's graphs. I am not sure what you meant by having amplifier with 4 ohm output impedance. They are usually specified for certain loads.
