Iwata horn 1 inch plan

[SebastienL]

Hi everyone,

Since I started my petite Onken project, I was attracted by the perspective to built a pair of Iwata horn as described in the old l'Audiophile magazine:

Pavillon Iwata en tranches (J.Ledauphin)

Now that I found a pair of TAD TD-2001, I cumulate informations on what could be an Iwata horn with a 1 inch mouth and its proper expension instead of the original one, which is a 2 inches.

I consider an acoutical cutting frequency of the horn at about 400 Hz and a cross-over frequency of 800 Hz with my Great Plains Audio 414-8C. I plan to use it in a 2 ways design which is the case I'm in actually with excellent results.

I'm wondering if someone have some plan for an Iwata horn around the specs I'm looking for.

Many thanks,

Sébastien

The above comes to mind.... Made in Poland I believe but not sure if it's readily available.
Can't find it on the original site anymore: Horns but one of the guys over there is a member on this site. Shouldn't be to hard to trace him...
