I think Joseph Crowe has done a couple of horns for ribbons, I think the main difference is you have to make sure, at what ever usage volume, the throat pressure doesn't become too high, otherwise the ribbon can rupture.
For a more shallow waveguide though I don't think this will be as much an issue.
Why not use a reinforced ribbon for a horn like the Founteks? I've never had to replace one yet, even after transporting them a few times.
Yeah that should work, I don't think it's a major issue, it's only if you play loud and load the hell out of it on a massive horn.
Hi all,
Is there someone who has measured the spl of the SB26 cdc in the augerpro 5" WG at 2.83V, please ? Would like to know if it >= to 91 dB/2.83V since sligthy loaded by the WG, at least in the bottom area from 2 k Hz.

What do the waveguide Pro's here think about this design?
I want a close distance between the drivers but don't compromise the waveguide to much.
(This is a 3D printed and coloured prototype - the end version will be routed from wood)

You could put the waveguide just in from of the woofer, so the edge of the waveguide covers the mounting flange of the woofer, and meets at the surround.
I have bad experiences with hard edges on the baffle like what you get when putting a flange or waveguide simply over some other driver. Therefore I normally just cut the frontplate of the drivers to get them closer.
The flange of the woofer also isn't straight - would mechanical not be easy to get closer. The contour now goes 1mm to the flange ... will do some measurements and find out if that's good enough.

you migth need it...or not, according the cut off frequency choice.
What is hard to route with the ellptical jiig from brandon ?

monty6400,
You can find the *.step files also on Brandon's site - those should give you the measurement in mm.

The STL from Brandon's site are in inches... Just open it in Fusion360 and scale it by 2,54x , and hit SAVE. Now you have a metrical STL.
Would you post some measurements with the 8NDL51 in a fitting cabinet? The original frequency plot at B&C homepage starts to make troubles past 1kHz - which was to low for my project so I never tried this 8".
