Pictorial of an exponential/radial horn being made for me by a friend...

[Bas Horneman]

Were those impressive badges laser engraved? I think oiling now would make 'em look better and blacker. Perhaps boiled linseed oil.

Nope....with the same CNC machine that made the mid and high horn.

Kees tells me that they look a lot blacker in real life than on the picture....but thanks for the tip!

I sold the speakers back to Kees. My wife was making my life a hell and I did not have the funds to finish them.

Here is wat Kees has been doing to them.

An externally hosted image should be here but it was not working when we last tested it.

wifes!

Those speakers are amazing!

Incedibly beautiful works of art.

 

[Pit Hinder]

not really amazing - had you ever worn a pair of klompen (the real Dutch wooden clogs - beware of cheap imitations and those sold to unsuspecting German tourists) you'd know that the Flatlanders are *beep*ing good at woodbiting.

OK, fun aside - there a lot of perfectionists about, but very few who have the ability (and tools) to convert their ideas into reality.

Full marks for Kees.

Sorry you didn't get to keep them

I'm blessed with an understanding wife. As long as there's not a speaker falling on her head, she's pretty okay with my insanity. Funny thing, I seem to self-limit as much as she needs me to, good match there.

They look great- is the crossover mounting machined teflon? Or ceramic?

Nice to have controlled directivity when you're having to put them against the fireplace, that'd never work with 'conventional' speaker types.

 

[Bas Horneman]

My wife is pretty understanding as well. But realistically it would have taken me 2 to 4 years to complete it. There is no way she would have those unfinished things in our living room that long. Giving up the speakers was sort of a self-limit as well.

The crossover is done on corian.

There is nothing to direct with these speakers.. music comes from everywhere, except from the speakers..
There is sound and there are speakers... Not there is sound coming from the speakers.. That's what everyone wants.. i have it

these lousy looking, cheaply made....with bad drivers..........

I don't believe ya.......

Hi Kees, that's a wonderful piece of work. Can you share the design details for the bass horn? Particularly the Hornresp model, I'm trying to learn HornResp, and am not certain that I arrive at the correct inputs. Either way your work is inspirational.

 

[audiomanics]

Oh, that would be difficult as i only have some drawings left in my CAD-program.. I only used Hornresp to find out which speaker would be appropriate and gave the best response, simulated.. Some parts where made while doing the job, like the wingshapes to brace the large panels.
I don't see your email anywhere else i could try to send you some of the drawings.. I have to convert them in some readable format for you.. (i assume you don't use the same CAD-program as i do..)
Calculating was done in some excel-spreadsheets.

Hi Kees, I'm using ACAD14. If you had a picture of the Hornresp input screen, e.g.: some form of print screen, that would be great.
