Hi Johnny
My choice is for Yuichi 480, the building is not a problem because my woodworker has a pantograph. I fear for final result: I want to be shure that sonically It will be good with JBL 2225h & 2425j.
Let me know,
thank you very much

Hey Audiophile,
If you are going to use this in home system you shouldnīt count on a XO-frequency higher than 4-500Hz from the 4560/2225. So you will need a horn and driver that does this. 2"?
Cutting straight along the red lines will change the horn. I would advice against it.
... I forgot... where I can find an adapter to connect the driver to the horn? In the original plan It should be in wood but for me Is diffucult to build. I have seen the adapter of old wood horn Fostex but I don't know where to find these metallic adapter!
Thanks for every help
Giuseppe
A 480Hz(like Yuichi flare) exponential adapter should be 1,4cm long. If the horn for example is Hypex=0,6, it should be 2,1cm. If making it that thick wood should be no problem.
What is recommended adapter thickness? THose Iīve seen seems shorter.
Still if you build that nice horn, what will you fill the gap between 4560/2225 and the horn with?
My intention is to do a cut crossover frequency at 1200hz, I have a friend with instruments for calculating this. Probably we will modify the volume of the box, I want measure the sound before to finish to restore the boxes so I will be shure of the result.
About the adapter I will try to built by myself.
