Default Waveguide for XT25

I am thinking of experimenting with a 2 way using Vifa XT25 and Vifa P21 8" woofer.
Does anyone here know where I can find a suitable waveguide profile for the XT25? I will probably turn a couple on a wood lathe.
Cheers
Peter

Here you have some nice waveguides for the XT tweeter:

Waveguide VP158/5030 for XT Tweeter

If you don't "master" the German language, use google translation here:

German to English

Elliptical wave guides offer more low end lift being able to be wider with a closer center to center driver spacing and controlled limited vertical dispersion

Many thanks for the links-very helpful. It would be very cost effective to purchase, but I would still like to diy some on a lathe. I have some thick cherry boards just waiting!

Damn they are expensive.
Would be cheaper in Europe to get the Dave Pellegrene (hope I spelled that right!) ones even if you were hit by everything the customs people could possibly throw at you.
If you are in North America I think the choice is a no brainer.

That said they look VERY solid indeed!

The xt25 is very happy in a waveguide. You can turn almost any size and shape and it'll work. Try some plywood and if the response is good cut the cherry.

Spinmonster...
The elliptical ones you use look really good.
I was thinking of about 8" round WG purely for appearance sake, and possibly overlap the 8" woofer a la Troels' TQWT. How critical is the center to center distance for the 2 drivers?
