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
 
112 dB 1/w/m 3ohz à 125 Hz à -6 dB

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:

can we have a little more info on this? graphs?
 
112db is on par with the Martin ASX, and thats a 21''

that's right it's ONLY 950X1200X546 but it's bigger than the wsx.
 
i have no graphs for the moment b ecause this horn is 12 years old (the V1) and was made for work with a phl oem ,and mr startec have made some rework on it to go with a  RCF LF18N401 driver ,there only a few peoples who had allready made and still waiting on the feedback.
 
here's a picture of the first party with the 3way full horn loaded speaker and the famous sbh 18 from mr startec:

The picture is the throat area of the terra horn. The terra horn is unfortunately not a DIY plan but is made be minaximal, a member of this forum. Minaximal's website for meta acoustics is online now so you can see a few more build photos I think.

I don't remember ever having heard the Quake, not many companies are using them, so I have nothing to compare the terra horn to directly.  My impression having heard them playing the same music and about 15ft away from LAB horns is that despite being fairly evenely matched in terms of SPL, they sound totally different.  The terra horn has a much more classic bass sound, it doesn't have the characteristic bang of a folded horn; the terra horns certainly sounded like they were going lower than the labs.  SPL was similar but I was putting less power into the drivers, I would guess that the LAB horns might ultimately be able to swallow more juice and have a slight SPL advantage when being ragged but I'm not really interested in pushing my horns to the limit to find out.

In my opnion they would be absolutely perfect for a reggae sound. They go far lower than most scoops without needing loads of them and they don't have the ultra aggressive sound that can ruin intricate basslines like on roots music.  I would love a big reggae sound to give them a try.
 
Neither the quake nor the LAB have the void in the middle but the snail folding is similar; the terra horn has the void to enable the folding to be smoother while retaining a 3.6m horn path.

yes but mr startec have now put this speaker in his brand (because he had put many time in it and was really happy with the results) and sell it allready make or as the porn horn you can buy it and make by yourself ,i think a pair is about 700/800 euro all finished ,i will put more info soon.
it's a HP PHL12" hornloaded , coaxial hornloaded 6.5"(phl)+1"(bms) with phase plug

Hi
 
Take a look at what Startec wrote about that SBH:
 
"Startec" a écrit :

 
Notez que j'ai un joker, 
une sorte d'arme fatale quelque part dans un tiroir; 
32oo watts, 112 dB 1/w/m 3o à 125 Hz à -6 dB ( et c'est pas des chiffres en l'air )....... 
Simple
 
Un vrai pavillon de 3 mètres avec le bon HP ! 
 
j'ai le plan (il serait nécessaire de le refaire car plus très lisible pour être scanné) 
C'est prévu spécifiquement pour un HP PHL 18 " (faut que je retrouve la référence sur une facture ça date déjà) 
le caisson de base fait 12ox95x52 cm , pavillon conique hyperbolique de 3m. 
4o>15o Hz, 1o7 dB( FC 57 Hz en 1/2 Lamda) 
Usage par 4 descend sous les 3o Hz. 
 
Ce super basse, extrêmement puissant, 
à été réalisé pour un HP PHL; 
ce composant étant une fabrication spéciale, il n'est disponible que sur commande avec une quantité minimum!!!! 
Personnellement, je n'ai pas envie d'investir des milliers d'€ pour stocker uniquement ce HP. 
 
Une modification est possible pour recevoir un RCF N4O1, HP qui se rapproche le plus, du HP Original ( mais avec 2-3 dB en moins toutes fois). 
 
voici ce fameux sub corrigé pour le RCFN184o1. 
Comme toujours chez moi, c'est assez simple à construire, bien qu'il y ai des découpes à angles. 
Je préconise l'usage de bouleau de 18mm (renforcé de 12mm pour la porte c'est important!!!) 
Le type d'expansion n'est pas courant ; l'objectif était d'obtenir un peu d'infra d'une seule caisse d'où la finalisation hyperbolique très marquée en sortie 
Ce pavillon descend à 4o Hz , 
par 4 sous les 3o Hz probablement 25-28 Hz avec le RCF vu les specs. 
( des mesures ont été faites à l'époque, avec le 18" PHL désigné, malheureusement, ces notes ne sont plus disponibles)

I need some more info on these tops - they seem to fill a much desired area in the market. I want some especially at that price!

The terra horn is a beauty - from a construction point of view, and im sure its performance is matched - but i really hate those bar handles - routed or bars but not both, ruins the original top notch construction i recons (not that it matters).

Note that I have a joker, a sort of fatal weapon somewhere in a drawer; 32OO watts, 112 dB 1/w/m 3O to 125 Hz to -6 dB (and this is not figures in the air )......  Simple A true house of 3 meters with the good HP!  I have the plan (it would be necessary to remake it for more more more very more legible to be scanné)
THIS is foreseen specifically for a HP PHL 18 "(is necessary that I rediscover the reference on a bill that already dates) basic chamber done 12ox95x52 cm, hyperbolical conical house of 3M.  4o>15o Hz, 1o7 dB (FC 57 Hz in 1/2 Lamda) Usage by 4 descendant under the 3O Hz.  This great low one, extremely powerful, to
realized summer for a HP PHL; this component being a special manufacture, it is not available that on orders with a quantity minimum! !!!  Personally, I do not want to invest thousands of € to stock only this HP. 

 
A modification is possible to receive a RCF N4O1, HP that compares itself the more, Original HP (but with 2-3 dB in less all time).  Here this fine corrected sub for the RCFN184o1.  As always at my place, this is rather simple to construct, although there let us are cuts to angles.  I recommend the usage of birch of 18MM (reinforced by 12MM for the door it is important! !!)  The expansion type is not current; the objective was to obtain a little infra of a single cash register from which the hyperbolical very marked finalisation in exit This house descends to 4O Hz, by 4 under the 3O Hz probably 25-28 Hz with the RCF seen the specs.  (measures were done to the era, with the 18" designated PHL, unfortunately, these grades no longer are available)

A really Superb Design by Mr Startec.. hope we could have more of his great works specially His midtops..Wink

Hi Myke, now I'm a bit confused on which of his two designs i would start to build.. the Hybrid Horn or these SBH. I will be using HDF cause Birch Ply is not available in our place, wish they could have here in our place Unhappy, and these would be really bloody heavy for HDF material. Need to import those birch from China or maybe in your place which is not practical on my part...

If your only going to build a few then go for the SBH, for shear SPL and controlled low end
 
if your going to build allot more then go for the hybrid
 
What ply do you have there, can you get 9ply? you must have a marine ply there?
 
HDF will weigh a tonne if you build that SBH

i plan to build 8 in all, 4 per side. but momentarily i will build the first 4, then later on the second batch due to my time limitation. yes we do have marine ply here but if i'm not mistaken its only a 6ply with a 3/4 inch thickness. I usually use HDF on my rectangular ported box, love the sound with less vibration... but heavy even a single 18 inch speaker in one bass cab.

 a stack of 4 SBH loaded with pd 185O = 111 dB /1w/m from 28 à 11o Hz à - 4dB. 
with 2 ohms 2ooo watts total; it's give 144 dB/1m with a thermic compression under 2 dB.
 
toxmaxtreme: i say that the mid horn cab will never be a diy project anymore ,startec had take to much time on it to give plan for free and he have put it in his brand. but anyway if you have the plan you will not have the phase plug and the oem speaker to make it work ,and what's 800 euro for a 3way full horn speaker ?? nothing !! it will probably cost you more to build by yourself.
 
to mikey: i will let you know more as soon as i get more info.

Many thanks DJ panoramix for clearing the issue...im just one of the hundreds DIY'ers waiting for the plan... but its ok Mr Stratec deserve the credit for his hardwork. 

WhhOW! 800 euro in our country is almost 50,000 pesos and thats a lot of money..Wink

Smile yeah i got your point mate, it would be still useless, i mean it would not still have the performance and the sound quality as the original design considering it uses an OEM driver and and a dedicated phase plug. 

hmm for a quality 3 way here, that would be much much higher than  800 euro..

will at the moment i will stick to the existing DIY plans here for the midtops..

sorry don't know but can ask for hornresp simulation.
i don't think they will go lower than the 1850 or the rcf ,i think you will just have more spl with the 1850 and the void driver.

ok ,so if the question was ,is there any mesurement done with void ,i say no. only simulation had been made with pd and void.
the only driver had been tested enough in real life is the rcf.
as i allready said ,this is an more than ten years old product and have been made specially for a phl oem driver ,and now as he get many peoples asking for a big horn he reworked on it to go with the rcf speaker.

@DJK

thats why I originaly was a bit shocked at it's 'not so big size'

in the photo it looked enormous, so i thought...yeah that will do the business, then I worked out its size from the drawing and wondered how how it would sim
 
because a horn with a 3 meter length could do with a bigger mouth
 
it's still doing the business at 30 though

This is one horn in 0.5Pi (could be 4 horns in 2Pi):
 
 
Note the 18L front cavity, and no dip?
 
Mouth about 6400cm^2, 80cm (31.5") square.
 
Subtract 29dB for 2.83V/1M, or 117.2dB/2.83V/1M. This is sensitivity, the horn is actually 4R at the sample frequency, so its real efficiency is only 114dB/W/1M.

You just need to manipulate Vtc and Vrc until you get the smoothest resonse.

If you examine the perspective view of this design, you will see a large cavity in front of the woofer before it opens into the throat. This gives a much more uniform load across the cone, and the cavity gets rid of the dip a half-octave above the Fc of the horn.

That the Tempest design, BTW?

All of Bill's links are dead because he hosted them at AA, and it's a paid service.

I only have a few saved to my hard drive, this one, a 70hz Hypex, and the rear-load horn with the Karlson slot. He has re-posted the later at his AH! site.
 
The Tempest woofer is a 15" similar to a Lab 12 driver.
 
Here is a graph comparing one of the above design, two of the above, and a double 18 reflex box.

Note the solid response to 40hz, and no dip.

Maybe try finding a driver with similar parameters to the Tempest - details available at the Adire library.

Same size would be a good start. Wink

Horn looks lovely. However, I immediately see the you have placed a 180degree fold at the end of the horn. I remember tom danley talking about the best ways of folding horns and that you should try to keep bends to 90degrees or less. He said that if you must put a 180deg fold in it, then place it at the start of the horn where the dimensions are small.

I belive this will limit the upper frequency response of the cab.

just my observation.

This is prolly a dumb question but might there be a chance 1 proline 3000 is able to run 4 of these beasts?
would 1 proline 1800 should run 2 of them?

I love that RCF driver by the way, if it the same one that in the dB tech 2 x 18 bins that is


I know this is probably a bit of a daft thing to say... but would it be possible to make it slightly wider eg 636 and then reduce the depth... how would i go about doing this? like the format.. but would also like slightly less depth and more width. Height is fine for me... but gaining the 636 width would be perfect for van loading in my experience and that might mean some depth could be lost maybe ? anyone fncy helping?
