the restriction on exporting .step files is the killer. If I can't create those it cuts all the CNC hobbyists off from my work.
I think the 10 doc limit is ok, I just have to save everything locally all the time.

More Bliesma T25B and SB26 results! Reminder these are 7ms of clean signal, no smoothing. Depending on waveguide size, baffle diffraction starts to show up @ 3-4khz. Basically if you see the responses getting wavy and crossing each other as you move off axis, baffle diffraction is showing up and the waveguide is losing pattern control.
Prints from my new Ender 3 Pro are pretty good. Everything is reasonably smooth, the contrast makes the layers pop more than they really are:
Is .... is .... is this christmas ? 🙂 🙂
Nice performance of the 1.2" deep 6.5 waveguides with sb26X ...
The bliesma is outstanding above 20k... (And before surely !!! 🙂 )
Did you try some distortion measurements too ?

Here is the Bliesma T25B on two waveguides with simple filtering applied, 0 and 40 degrees (which I find to be a quick and dirty proxy for power response or early reflections). Hopefully this is a cleaner display of the performance we're talking about.
BTW since the Bliesma designs went so well, I didn't have to spend a ton of money. If I can reach my gofundme goal of $750 I'll buy the 3/4" Scanspeak d2104/7120-00 and 1" Scanspeak r2904/7000-05 and start working waveguides for those. I did a circular waveguide for the 1" Scanspeak ring radiator for the Monkey Box project and it came out well so I'm hoping it will be easy to do more variants. A big 8" waveguide to go deep might be a nice match!
Whouhou ! Thanks you so much for your time and effort !
I'll launch my next project based on your WG next week 🙂

Whoa, I've asked a quotation from i.materialise.com.
The previous 5" model was about 45 euros, but the new 6.5" is 100 euros !!
The new 5" is about 37 euros
I presume it is related to the amount of needed material, does it mean that new models are more solid & dense ?
Do you have some distortion measurements ? Maybe new ones are less prone to resonances ?
Regards

Hi Augerpro,
I just approached my project using your older 6" version for the SB26ADC.
I see now you have a slightly larger 6,5".
Are there any significant differences between these differences, despite the size?

I don't think ever did a 6" for the SB26 prior to this group. Maybe you could link me the post you are talking about.
Yes there is a change. Before, the tweeter mounting flange was a 1/4" thick sort of "disc". Now it is a large block. I did this because a CNC could not mill the disc, and I didn't want a whole bunch of versions of a single design to keep track of. When you get bigger they get spendy, although those prices seem high for PLA. If this was SLS nylon then I can understand that, I think HP is the only manufacturer of those printers.
Thanks you.
Yes it's sls printing.
Ok, and at thé same time the 5" is lighter because of these méthode, that it?

arnandsway> I can't find any results for that one, I don't know that I ever printed it. There have been major improvements in preventing printing issues with my new stuff, so I wouldn't use that old version. Is there a reason you are looking at that one?
Well, maybe stupidly, but I already have it printed and also made a cutout for my speaker with it... So that's quite unfortunate for me, but the newer 6,5" versions won't fit in my front now. 
So I will test it and hopefully it will be good. I will be using it for a 2-way design.

A couple weeks ago I ordered a pair of the 5" SB26 waveguides for my 3-way tower build. They came in today and I'm very happy with the quality, so I figured I'd share details!
Vendor: Xometry
Material: SLS Nylon 12
Finish: Media Tumble w/ black dye
Cost: $125 shipped w/ tax for the pair

arnandsway> I have results from a vA that look good, but none from vB. Likely I made a small tweak to profile, but shouldn't be a large difference. It's also possible there was no tweak to profile, but just other little features. Should work pretty well if it is at all like vA.
black300zx> looks great and that's not a bad price either. What's the intended application in your design?

They'll be paired with Peerless 5" HDS mids and 8" peerless HDS midbass/woofers. I have very wierd room geometry so I'm hoping the controlled dispersion will help control room reflections. My first time using waveguides, so it's also an opportunity to learn & experiment. They look pretty neat too😉
