Is this project still ongoing? Has any progress been made?

I am using TH-4001 clones on my TD-4003 drivers and would like to try something else. I would be interested to see how you tackle such a challenge.

Hi Alois,
We have decided to use the Radian 950. The Iwata horns will be CNC'ed around september where we will try different adapters to cope with the Radian drivers very short and 20 degree angled throat. I'll be back when we get there.

Regards
Peter

Hi Sannax,
The two 1:1 files can be downloaded here:

www.peterdupont.dk/Iwata_bottom.pdf
www.peterdupont.dk/Iwata_side.pdf

We are still working on the lathe for routing the Iwata top/bottoms - but there has been a lot of annoying inbetween stuff which has slowed things down.
To be certain we have everything in order before we start up with expensive wood we have experimented with the much easier TAD.
I'll get back when we get further.

Regards
Peter

I think that the drawings came from an article in the french Revue du Son. If anyone has other maybe more precise drawings, please come forward.

Regards
Peter
