Tractrix Horn Build.

75 posts in this topic

Hi All

I know there are some keen DIY'ers here on WigWam, so this my (our) current project - a Tractrix horn build.

Calculations, Cad drawings, staining, varnishing etc all done by me - the wood turning is done by a pro-friend at mates-rates.

Initial detail -

wooden tractrix horn.

Drive unit - TAD 4002

Tractrix horn - 300hz horn, I cross it over between 600-800hz, we will have to see what sounds best on the new horn.

Looks fabulous so far! (Not that it won't look great when it's finished, of course.)

Nice to see pics of the stages involved.

I assume that is the template for the curve for your friend to follow on the lathe. Oh and thats a bandsaw btw:) what wood are you using?

the ''inner'' tractrix curve - stuck onto board, and cut carefully!! on a jigsaw.

I really wish I had the skill to do this kind of thing. Had I even an ounce of the aforementioned I don't think i would have abandoned my horn project quite so easily.

Yes I wish I had the skill and the tools, it would make my horn obsession a lot less expensive! Looking forward to seeing these evolve...

Hi

Yes, template for inner curve. I've gone with birch ply, to see the side-grain on the finished horn - like with Cessaro.

Great stuff Chris,

I'm smack in the middle of making some JBL H9800's using the layered birch ply approach(cnc'd throat) too.

hi,

basically am currently using a type of copy of the TAD 2402 speaker

product_704180_o_1.jpg

I use a 1601b 15" (tad), Tad 4002, and a JBL 2405 as a tweeter.

The mid-range horn which this will replace, is a copy of the TAD one shown in the above image.
