J-horn is like JBL 4560 - this is all I know.

I've used additive silicone to form OS throat in 12cx. Those who have OS-12 waveguide can easily make it in one weekend.

Caprolactam plastics are very useful for making phase plugs and adapters - below is plastic insert for LCY ribbon forming 25mm throat. It takes 10 minutes to do - put in hot water and press into the housing.

What is the throat angle on the JMLC 400. I am looking at it as a alternative to the azurahorn 425. Also, how can we have it painted in other colors than those offered. I would really like to match the grey of my Altec 416's. It is like a charcoal grey.

5 degree as usual. Maybe Nextel Grey would work for you?

The Nextel grey look great. I ask about throat angle because it will match up with Altec 288/Radian 745, and I think theirs is 7-8degrees. Is it possible to get the 400 in 1.4" mount and that throat angle?

Yes 5 degrees is at 1.4". Ask Autotech for availability with grey Nextel, send PM to info@autotech.pl or better to diysoundgroup.com

jzagaja,
I saw the design published in stereolplay You send in pdf here
it is huge handy work, effort and precise finished elements
But the total design is not good. it is little of the amateur outfit.
the main elements are OK horns ets
BUT
the connecting parts are not designed well
and their outfit is opposite of the rest, sore of the design issue.
they are forced curved putting into global look to many curved lines.
mainly this black round barrel line carring the central horn and top little horn is
biggest alien. shape, material possition and kraft.
dont get me wrong but maybe consulting of a pro-designer is not bad idea?
second it is so huge contrast. Should be but not that much
horns are white so this black parts should be not total black but some grey variant,
or natural metal color
dont take me wrong but theese things is somehow can underestimate the main idea
and good based concept. Dont You think?
I post this not to underestimate acheivement, but rather to implicit the not so good points in generaly good design, please dont get me wrong

keep good work

Thanks for thoughts. As you may know - I'm a friend of Autotech just helping keep everything alive - hobby work. AT doesn't use any external designer - this is a family business. They just trying do good job with passion - not everyone like it that's for sure
