I want to build a pair of C-Horn speakers... I've got Fostex 206EN (and some other nice sounding 8incers) I have CNC at hand but I have no idea about the cutting plan... any help is appreciated... 🙂
as I can see there are two different versions... first one:
and this version which seems to have one more loop in the horn section:
what is the difference between these two?

That is gorgeous. I bet that acrylic wasn't cheap!
How's the response?
Is that a horn sub in the background? Looks nice
Good work!

Haha I just realized you said you want them... not that you made them.... That's what I get for reading too fast haha
Are these horns designed through hornresp program? Has anybody modeled anything like this for diy community? Ariyahoor, you should also look at Dallas horn, seems to be excellent for the driver you have, as some builders have reported. Do a search you will find plenty of info on it. Stylistically Chorns( at least to me) look lovely.
😛 I wish...
ooh I didn't know... I though it's someone's contribution to DIY community... excuse my mistake 😉
ha ha 😛
I don't know what program is used but as they are Commercial designs, I just have to design my own horn. I'll do it with CAD. Plexiglas should be cut with Laser Cutting machine which is at hand. internals are CNC job
I'm from Iran and buying flat kit of C-Horn from Andrew would cost me very very expensive... I've got CNC at hand, I PMed Andrew if I can just buy the design and patent of his product... He will take his money and I can build the slices myself and everyone would be happier 😛
No I don't think so. Acrilic (Plexiglas) should be cut with Laser cutting machine which one of my friends have
Intriguing looking speakers, but I wonder about the purpose of the circular cutout just below the driver.

I think the circle cutout you mentioned is all about appearance and refers to the name "C-Horn" ... there shouldn't be any sonic purpose behind it.
footnote: I might be wrong... designer might come up with a different answer

At the expense of comb filtering distortion from the cavity resonances, delay............

So it would seem. I wouldn't have it either, but I guess they're willing to trade that off to obtain the desired looks.

Plexi (Poly methyl methacrylate) certainly can be cut with water jets and lasers, but you can also use routers and cnc without optical loss. (per one of the manufacturer/distributors:
PLEXIGLASS - Plexiglass Sheets - Discount Plexiglas® Acrylic plastic sheets for sale: clear, colored, frosted in stock - custom plexiglass is easy to order.
Many ways to skin that cat.
I'm gonna tell you something you won't believe 😛 I estimated all costs and whole the project (MDF + Plexiglas + water-jet or laser cutting) will cost me only about 400USD 😀😱 except final painting
but I won't copy Andrew's commercial design... I'll design my own horn... the only similarities would be acrylic side panels... that's it 🙄

well over here ( west coast Canada) the Plexi sheeting alone would cost several times that, then you calculate the machine time to cut it and all those layers of MDF, assembly and painting...
BTW, you could cut plexi with a chain saw if you wanted, but ending up with nicely polished edges as seen in the photos is a whole nuther story - and as for laser/waterjet/highspeed diamond coated CNC etc, the finer the edge the cutting tool/material leaves behind, the more work required to make it safe to handle
you're right... I double checked and found out that acrylic price had a huge increase in the market... I'll need 1400 mm * 2400 mm piece of 20mm acrylic which will cost me 6720000 Iranian Rials equal to 370USD... taking this into consideration, the final cost would be something around 600 to 650 USD which still seems fantastic 😀
