Hey Auger,
Is there any chance your waveguide design methodology interacts in a useful manner with small cone drivers?
Something like the SB65WBAC25 2.5” fullranger?
I’m assuming the input hole will be so big that it’ll have no effect on the >4k hz dispersion?
Just curious!

Hello, I have a general question and don't want to open an extra thread for it.
I'm trying my hand at FreeCad and I'm wondering how deep the waveguide depth has to be so that it is flush with the front baffle.
I'm not sure if all versions have the same depth, I'm aiming to use the one for the Bliesma T25B, which should be 6.35mm deep. What headroom do I need for the speaker sealing tape? Would a depth of 7mm be sufficient?
Some people here have already used augerpro waveguides, could they share their wisdom with me? 🙂

Have you looked at these supposedly Be cheap tweeters that measure very well. You can find measurements from a few different people.

If you need a WG for it, perhaps consider purchasing a single unit and sending it to augerpro?

Davidlouis (eBay) or Melodavid (AliExpress) tweeters are good candidates for waveguides. Faceplate is flat aluminum plate, and voice coil assembly isn't weird, nice flat mounting surface. Photos here (also photo with faceplate removed in eBay page linked above):

6 in version measures and sound much better in my case than 4inch. Much smoother
Now I am printing phase shield version to compare.
I don't see anything wrong with them. Can you post screenshots of what your slicer is showing or something to help me understand what the problem is?

STL file is wireframe by design, however resolution is high enough to result in a clean print. If you want perfect shape profile, stick to the STEP file.
Right.
So if the surface finish is a bit lumpy, is the solution to increase the infill %?
My (outsourced) 3D printer has dropped off the phase shield, and the surface finish is not as smooth as, say, the WG148R or WG300.

No, percentage of infill has almost no effect on surface finish. Orientation of the part on the bed, good quality dry filament in a printer with a well tuned profile is what you need. Unfortunately I don't think the library will get you there.
PLA process? SLS or MJF nylon will not have layer lines like PLA. It leaves a sort of sandpaper feel that should be smoother than the slightly rough Visiton waveguides. Even with PLA you really shouldn't see the wire mesh, just layer lines. So I'm not sure what issue rafabro is having, or if just the look of the model in software is concerning him when it shouldn't.
