XSim free crossover designer

[AllenB]

The two (cabinet impedance variations and crossover interactions) happen at different parts of the band, limiting the effect (in some cases more than others). Ideally you would but if for some reason you can't include the cabinet influence, don't let it stop you designing.

 

[jmpsmash]

can anybody light me up about this? Should the effect of the cabinet on the impedance be taken into consideration?

always use the impedance measurement with the driver mounted in the cabinet.

how to use the esr value for capacitors in the crossover tab? since esr changes with frequency

 

[kimmosto]

Leave initial value as is and focus to something relevant.

started to learn using this application and it's very easy to draw schematic, plus using "fpgraph tracer" for having fun.

however i got this error while loading frd files, both from FPgraph output or from below link that i download

http://www.rjbaudio.com/Audiofiles/FRD files/ScanSpeak 9500.frd

when i open this frd file, i can understand it easily since everyday i'm dealing with database for analytics. header will be : Frequency SPL Degree

with this simple txt file, still wondering what's wrong with my import process

 

[AllenB]

I just tried the file and it works.

For debugging you might try deleting the driver and starting again, if not then save the project and restart XSim.

 

[gadut]

great, i just created a new project and frd files can be loaded properly.

new trick

 

[gadut]

XO design part is completed with values and curves are populated, when i close and reopen project .dxo file then error pop up.

opening project .dxo file in notepad, any clue on which value that related to the error "Floating point division by zero".

great, another trick solved now

I keep getting a "file load error!" when I try to input frd and zma files traced from FPGGraphTracer. Anyone know what this could be?

 

[AllenB]

I'm thinking headers, possibly delimiters...

 

[bwaslo]

Could that program be using commas to mark decimal places (rather than a period/dot) in numbers? If so, XSim won't work with that.

 

[sardonx]

Thanks for the quick reply. But I don't see where. They are decimals not commas. Maybe I didn't do the trace properly.

 

[bwaslo]

I think I see two problems with that data. First, the frequencies (first column) need to be in ascending order, lowest frequencies first. Second, could that be a negative [-] sign in front of each frequency???

 

[sardonx]

Yes you are correct. I've already starting working on it! My first time doing this

 

[sardonx]

Yep, a negative sign!

 

[sardonx]

Success! Thank you very much.

I was wondering if anyone would be willing to look at my first XSim XO before I start ordering parts.
