I am a cabinet maker working in Bristol, UK.

I am starting an audio company, the first product I am producing are custom small turned 1Khz+ JMLC horns, with hopefully lots more products to follow. Picture of these solid American Black Walnut 1.6Khz and my thread with more info. Priced initially, amongst the diy community at £100 Base price, plus shipping.

If interested please reply on my thread or PM me.

1Khz wooden horns for sale, interest?

Does any-one know the throat angle for the E-JMLC 600?

not much i guess

biggest issue might be to achieve exact matching hole size
and the small edge you get when mounting

besides, due to center plug or diffuser, exit throat area could appear to change quite rapidly, and result in totally different exit 'angle'

The throat angle of the EJLMC 600 is more open and is hyperbolic angle.
The throat angle of TAD 2001 is conical angle.

2 pictures attached.

Best regards.

Vertical is zero and horizontal is 12,4 deg (half angle).

Thanks tinitus,

Thanks Eric(who I pm'd on the very topic) for the pictures
From what I have read/understood, better matching of the two (driver exit angle and horn throat angle), results in better response. Are there any guidelines on what this difference should be for optimum performance, and is there a point of diminishing returns?
If matching of the driver/throat angle is preferred, it would be nice for horn vendors to provide this data.

jzagaja,
Wow, thanks. Okay 2 angles, 2 many. Contemplating on horns for my TAD 2001 (long term project ..... like all my projects). The 2001 has an exit angle of 3 degrees. So

Edited [ OK, not 2 angles, infinite ... re-reading Eric's post]

Question : Horizontal/vertical swapped in the picture?

No cut the hair in four parts.

The EJLMC 600 + TAD 2001 is one of the best of the world médium / treeble system.

No need to modify any thing for have a very good sound.

Mine turn with a 6C45PI diy SPUD amp. With the sound is the best.

Voilou in french.

Eric
