here are a new 18horn plan made by a french guy called Startec (Quad Acoustics),this plan is made for a RCF LF18N401 (cheap solution),Void V1OOO (mid solution) but you can use a pd1850(expensive solution).
It's a 3 meter long horn ...  Clap

The horn folding looks rather 186/1850-esque, but with a cunningly repositioned driver to move the front chamber and add more length.

Looks good on paper - how does it sound?

it's sound f**king good ,the only problem is it's really big and make 60/70kg(without speaker) when you do it on birch-plywood!!
 
this one go really lower than 186/1850 and the chamber is bigger ,so it's don't sound like 186/1850.

Yeah, it looks like a bit of a beast! 60-70kg isn't stupidly heavy for a bass bin though.

looks great, I think this would make a good alternative to a labhorn for those with less money to spend on drivers and less carpentry skills. The chamber looks big enough, and the compression ratio low enough to allow for cheaper drivers than the 1850 horn. I'm sure it is very efficient too.
 
Have you tried it in groups of 4 or more?
 
where can I hear this beast?
 
Have any French sounds started building them yet? It would be good to see a french rig without a pile of w-bins or martin audio speakers, they might discover that life doesn;t end at 50Hz! (Sorry for the terrible generalisation but I'm sure you can see where I'm coming from!)
 
It's a shame it isn't quite big enough though!

Is there a reason for that tantalising pic of the Terra Horn bitoec?

Nice design, btw. Fills an important niche - 30-126hz -6dB sounds greeeat.

Does it need a kick bin?

For comparisson I suppose, I hope it didn't come accross as showing off. There's only so many ways to fold a 3m+ horn into a reasonable shaped box and it's suprising how different this new design is. The Terra horn follows the same folding pattern as the EM Quake and the Lab Horn really whereas this design is an innovative extension of the 1850 style S-bin fold.
 
The fact that the driver is loaded from the front in this design limits the throat arrangements you can have. I never had any problems with this style of loading in the 1850 horns when I had them but I have a preference for the style of throat used in the ASS folded horns (BS1200, etc) and the punisher where the driver is firing onto a parallel plate and the expansion is the the other plane for the initial section. The terra horns are a kind of combination of the two.
 
 
Opus get around the uneven loading caused by the throat arrangement in this new design by putting a weird shaped bulge on the access panel. Perhaps the designer of this cab could esperiment with this to reduce the front chamber volume and even up the loading?

Don't worry, meant nothing of the sort!

I was thinking of something like this for evening out loading as well,

Mykey also uses a bulge in his Brute 45.

Either a piece like this (courtesy of Tony ASS) or a letterbox martin style:

I remember seeing the build thread for this awhile ago.

 
Anyone have a link to it.
