Open source Waveguides for CNC & 3D printing!

I like MJF too
If you are going to bother with the time and effort to build a speaker just get the good stuff, seconding MJF. The glass filled PA12 MJF is a good deal stiffer, more dimensionally accurate, less susceptible to hydrophilic issues, and a bit denser. Did my last pair of 6" WG with MJF glass filled and it looks great and a marked improvement over the PA12 alone I did for my 5".

Expect to pay $200-250 for a pair of 6" waveguides. You may be able to cost optimize the design under $200, but I wanted the mass.
 
Any chance you would be interested in experimenting with fabricating a lens like that on the Seas 27TBCD/GB-DXT but for the T25? The Seas really has amazing directivity control across its range. It might be fun to try to replicate that for another tweeter.
The DXT lens introduces intentional diffraction to control directivity. Waveguides like Brandon's do an equivalent job of controlling directivity without introducing severe changes in curvature. If you want something the size of a DXT for the T25B why not look at Hificompasses W104 waveguides?

For crossing to a 7" mid(woofer) a 6-8" waveguide would be better than a 4-5".
But for a pure midrange duty, that 5" Faital is a better driver IMO and for this, a 4-5" wg would be enough and the tweeter probably would be happier too with the higher crossing.
 
This woofer cannot keep up with the mid (if you really want to combine those two drivers).
Why not use a more harmonic combination? This mid would be good with a high efficiency 10-12" woofer.
Or you could spend less and use a smaller, lower spl (cheaper) mid.
Just my 2 c.
 
Do you mean the correct dimensions for the wgs from augerpro or creating your own wgs?
with the auger wgs you only need to change the units from inch to cm in fusion. you can do this in the fold-out area at the top left.
or do you mean creating one yourself?

EDIT: Ah ok im stupid your a from america, inch is probably already correct in your case 😀

if you want to design your own WG you might want to follow this tutorial:

Or you could try something like i did.

You can create several construction planes in Fusion on which you can then place your sketches. The projection command gives you the same center points. Then draw the shape of the respective waveguide section on each plane. Then connect these with the elevation tool, but not the one from the shape/body area but from the surfaces area. I'm not quite sure anymore, but I think you still have to make a body out of the surfaces with the stapling tool
I hope I have translated the individual terms correctly, as I used fusion in German.

I would also be interested to know how others create their WG in Fusion. After all, there are many ways to Rome

Here is an example i made. This is the part where you use the "elevation tool" from the surface tab.

To make a body out of it, however, the surfaces must also form a body, the picture now consists only of surfaces, you cannot make a body out of them. I hope that is understandable.

And as I have only been using fusion for 2 months, I would also be very interested in other approaches.

I am struggling to get actual dimensions of 5 inch eliptical and 6 inch eliptical for satori-tw29tx in fusion 360
I am trying to draw up baffle for cnc cutting.

5": 5.78 x 4.88
6": 6.78 x 5.77

I just noticed the oddest thing. When I download an .stl from my website and open it in F360, it is scaled down in some way. Maybe 1/2 as big. They still print fine since many people have printed this already. Interestingly when I download and open the .step version, the dimensions are correct in F360. Anyone know why this might be happening? Why would F360 incorrectly read an .stl that was created in F360?
 
Take the nominal width, say 5", and multiply that by the aspect ratio. In this case .82 (as seen in the waveguide name). That will give you the dimensions of the primary ellipse that everything is based on, and would be the size of the cutout hole you need. In this example: 5" x 4.1". The mounting flange is .39" on all elliptical waveguides, so you can add that (x2) to the width and height of the primary ellipse to get the outside dimensions of the whole waveguide.
