Steps 3 and 5 are redundant. Not sure that's the difference though if your deleting the loaded files and importing the diffraction ones at step 9. -
Check the files loaded for your woofer. Perhaps just work with the horizontal diffraction files for now, remove the rest. -
These are the FRD and ZMA trace files I made for the tweeter. Along with the 0,15,30 diffraction modelled FRD's.
Also on the driver tab of... -
hmmm hard to understand what the difference is but it seems the impedance and phase might be the issue. I'll attach my trace files for the tweeter. -
No the mic should be in front of the woofer - the driver offset is taken care of in the crossover model. 11.95sd noted - it doesn't make any real difference... -
I have to say I'm pretty surprised. I wouldn't have even considered a 10" two way (and probably still wont) but if everything here translates from... -
Here is an update showing "purchasable" values.
You will want to keep the DCR (resistance) on the inductors to a minimum. This...Leave a comment:

Apologies I just noticed I had 'open baffle' ticked at some point running the diffraction model. I re-ran the models to be sure with the following updated...

Totally agree. Often a cheaper woofer/tweeter results in a more complex and expensive crossover particularly when stretching the limits with a combo like... -
Should be fine with this tweeter - its about as low as you would want to go but the third order network keeps it pretty safe.

....and to illustrate how important tweeter position is - here's an amended result based on a slight reposition of the tweeter for a better diffraction...

Yes, you definitely need to model the tweeter here in the same way. The output files are the new 'anticipated' frequency responses for the drivers in... -
Just based on a guestimate baffle size and speaker positioning. Potentially some off axis issues.

Chris has included BFC in his recommendation. But as you can see this is a classic example of why real measurements and proper modelling are required... -
Just an extra tip with this - I generally don't decide on the tweeter position and build the baffle before modelling diffraction. IMO tweeter position... -
This will give you a full set of diffraction modelled response files for your woofer. Start with the FRD file for on-axis (0 degrees), setup your baffle...

That 1.5uf cap and 4ohm resistor go across the first 2.5 inductor...in parallel with it. The 8ohm and 10uf cap go from + to - ahead of the woofer, not... -
Here's an example of a 15" sub with a 6" port. https://www.audioholics.com/subwoofe...se-and-xv30fse - those aren't... -
Could you not just port out the front or back and avoid the issue altogether?
Trying to use the air gap between the bottom of the sub and...Leave a comment:
