First start of XSim, but...

[jeffrowland]

once installed it is very simple and intuitive, but when I go to create the .zma file, it does not create/save it. maybe I'm doing something wrong...
so I installed VituxCAD and repeated the simulation of the mid-wwofer with the values used in the two-way.
I'm shocked!

 

[AllenB]

The same as Xsim, yes?

 

[jeffrowland]

no, with XSim there is no simulation. I check and find any test .zma file.

 

[temp25]

I don't use Xsim, but I don't think it creates a zma. I think you load a zma for each driver.

 

[AllenB]

Both create default flat drivers until you change that. I checked it anyway and they both give the expected result with this circuit.

The 3.12mH coil is too large. Usually that coil is smaller than the first one. Obviously, it depends on what you are trying to make the filter do.

@AllenB
I confirm that the simulation is the same on XSim, with 8ohm of the driver, instead I should work on 16ohm.

@temp25
now I'm checking the low pass again, but this is the result of the audio tests performed to attenuate the excessive voice of the kevlar mid-woofer

-> this

 

[AllenB]

This looks like the resistance of a 16 ohm driver plus the meter leads. The impedance would be higher than that.

 

[jeffrowland]

that's right, if you remember in fact and then also confirmed by the Wharfedale 1334 model it is a 16ohm, however in the simulation in XSim I cannot change the impedance and not even create the .zma file which as you can see would be possible, but it does not create it.

 

[AllenB]

Open from here.

 

[jeffrowland]

but of course Allen, the problem is that the file does not exist because it is not created.

 

[AllenB]

Normally you'd either measure it or trace it.

Here's one I created that is 16 ohms.

 

[temp25]

Or download one from Parts Express.

 

[jeffrowland]

he uploaded it and I also saw the content.

I changed the values, but this way I'm sure that the voice will become invasive again as in the various tests I had performed.

 

[temp25]

Are the two 16 ohm woofers to be wired in parallel?

Have you measured the frequency response, and made an frd?

mtm?

I cannot change the impedance and not even create the .zma file which as you can see would be possible, but it does not create it.

To make generic impedance files, I've had better luck opening an existing zma file in Excel, modifying it there, saving as tab delimited text, then changing the file extension back to zma.

Bringing in files generated by other hardware/software has worked fine for me also, with just changing the extension to zma.
