New Horns

[aktivkampi]

Hi, here are some news from my Hifi System!!!

After some experience with my 2360 Horns, the result was not really satisfying at all. There was always trouble in the upper midrange, no passive eq was perfect. Active digital crossover (Behringer DCX 2496) did to much noise for my ears. So I tried the 2397 with good results, but the sound of this setup was to much "hifi like" for me. After hearing the TAD TH 4001, I started some research, but there was nothing I could find. It seemed to me, that the Yuichi A 290 was the closest to the TH 4001. A friend of me converted the plans for me into CAD, a CNC maschinist did the mechanical part. The first hearing was very satisfying, its a combination of both worlds (the directness of the big boys and the behavior of the 2397). Now the horns will be coloured, for you some first pics......to be continued

....some more pics...

....and this is the colour, the horns will get....

really nice

That also looks easy to assemble!
Would you mind sharing the CAD plans?
Are you going to sell some of these?

What driver are you using on them?

@OP - Great job!!!

Would you mind sharing the CAD plans?

@POS - They are available here.

these are just drawings scanned in pdf, no real CAD plans

The shop that will do the CNC work will most likely want to redraw them anyway. They will have better control on the process and a better understanding of the steps. Doing the cad is not difficult...

I see what you mean, and I imagine each CNC machine will have its specificities that will impact the final plan...

I would love to try a scaled down 1.5" version of this horn, and see how they compare to the H9800.
I think Woody Banks build such 1.5" A290 horns for his 2435HPL one or two years ago...

@ pos, thank you for the complements....

Im using a D.A.S M 401 driver. It is similar to the JBL 2440. I' ve tried different Dia's, with different results. Sharing the plans is possible, but no good idea, as Lee told, the CNC Shop will need their own plans......
Selling is maby possible, but it's not really cheap ! Please send me PM.

Nice work!

I'm always impressed with people that actually do and not just think of what they might do.

I'm sure they sound good as well

One question: have you experienced any problems having the 077's in a position so far back? Though a location near or in the same vertical plane as the mid driver seems like the way to go phase/time wise, it would seem you could get a lot of reflections from the top of the mid horn affecting the 077's response.
Any thoughts about this?

What do the rest of your system look like? Did I see part of a 2206 in the pictures?

Hi Jacob

I've done various experimentation with the 077 and for my ears, that positioning is the best possible...... and even easy to handle!!! The rest of my system is 2 x 2235 in 160 liter cornersubs, actually 2206 as low-mid (but Í've got 2 brand new TAD 1601a) which will follow the 2206. Mid High is the new horn with D.A.S M 401 driver and the 077. Driven 3 chanel active by an analog crossover, the part between high and mid high crossed passiv.

Do you feel that the 2206's are not good enough for the low-mid bandwidth?

There are many handy people on this forum. The sharing of ideas and methods is great too.

I am surprised more people aren't doing this. Most 3 axis CNC'c will do this stuff quite easy if you can produce a model. Making horns out of MDF would offer better sonic results than the originals if anyone wanted to make a copy. Down under there are plenty of shops that would be glad to do this sort of thing.

Hi Ron,

the 2206 is really good, but the TAD is better !!! You will have much lower distorsion, clearer mids, the speaker is a little bit louder and can go to a lower crossoverpoint to the 2235 (50 Hz / 24 dB). But as I said before, the 2206 is really good.....
