Exactly. And I like the nice and even response of the off-axis curves too. I hope that Purifi makes a 5" alu midrange - that would be nice.
After I started using your Waveguide on a SB26ADC - finding how good a rather cheap driver can perform, when used well. Then I just wondered which midranges could be the best to match the great performance of the smooth curves of the waveguide.
The little Textreme has its breakup much higher than the Purifi. With a passive network, it should be possible to suppress it, though. But when I have an active setup, it feels almost wrong to start fiddling with passive components too.

Maybe it will work on tweeters too?
Sometimes it's just the thought about something that is maybe better. Like maybe the Textreme tweeter could have one of your waveguides, rather than the small one it is born with. But would it really be better? Maybe only the BE tweeters are better, because they load the waveguide better, with the flatter dome structure.
Is there something specific in a tweeter that you go for, when designing a waveguide?
Yeah, I hope it will work on my waveguide!
Seriously though, it is tough to guess how a tweeter will interact with a waveguide. Flatter domes do help, and smaller surrounds. But there are always exceptions. I'd love to see how the SB Textreme or Be tweeters look on the waveguides I made for the fabric Satori. I'm currently developing a speaker using the MW16TX and T25B, but I want to make sure I'm making the right choice by taking a look at some other high-end candidates. Both of the SB domes look pretty flat and might load well. If anyone wants to loan me one, that would be a great help.
Anyone work with AMTs on waveguides, or hear them? I'm going to work on getting my AST2560 on a waveguide. Only example I have to look at is the Beyma TPL150 model.
IMO the Purifi has a better motor and likely a more natural spread of harmonics (proportions from lower to higher order HD) in its pass band than the Satori. Most smaller cone mids don't do that well down into the lower mids. I've heard different versions of the MW13 and wasn't all that impressed when comparing to others in that price range.
Snicker if you like, but the Peerless NE149W is still one of the best 5" mids I've ever used at almost any price. It just sounds very clean and neutral, even crossed lower than usual. Very sad its almost impossible to buy now.

Joseph Crowe maybe ?
old AST2560 or a recent one ? Are said to be less good from few years (concistency issue said J Holtz)
I have the old ones, but if a waveguided version works well with my speakers, then I would pick up the new ones to model for a published design. I know the new ones drop a little sooner on the low, but everything else is the same as far as I know.
the old one .... lucky you 🙂
Edit : Here in Europe it can not be found, there is Harwood brand that is said to be the same, but some noticed it was not exactly the same model...

As I am too mke print a 10" wave guide foe a 1" CD, I also sent your stl file of the round 6.5" sb26 WG (as I am pretty too much a beginner to try the other shape) to mate with a 6" to 7" midrange for a try with the SB26ADC. The guy at JLPCB (I told them to convert x2.54 to have the centimeters) showed me a 7.5" diameter WG . Is it correct or should it be netto 6.5" width, please ? I will order in ABS !
Is the 7.5" diameter of the mouth correct, please ?

total diameter with mounting flange is 7.28". There is also a 6" that is 6.78" wide that works well with 6-7" drivers.
ABS is alright if you don't have access to SLS nylon or MJF processes. I would print in those if you can.

When my current project progresses to the point where it can replace my main system, I will consider sending you one of my TW29TXN-B tweeters. It would be cool to have a waveguide option for it.
Someone stepped up today and I have one of the Textremes on the way. When I find out which one I'll let you know. Thanks Jim
TXN in Jantzen WG does not look bad at all 😉
Measured in 2way cabinet, with 20mm facets.

Thanks, I am talking of the round one in 6.5"... seems the stl. shows 7.5" according JLPCB. They have not converted in cm yet. See the picture they sent.
Is that the good stl file, took it from your site in the 6.5 round WG SB26 section. Has anyone printed it at Diya, please and can help ?

Ah, that's right, I left the mounting flange at .50" for the circular waveguides because the routing template for the elliptical ones required me to shrink that to .39" to use off-the-shelf template bushings.
So that is the correct dimension.

I will try to measure this week, when I get to my hifi-office. TXN dome is quite flat, similarly to Be version.
