www.freetransaltion.com

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)

Quote i think a pair is about 700/800 euro all finished


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).

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)

that's my friend Kev at frenchtek this year.
 
You can see the mattress he has in there, it damps the vibrations and its actually pretty comfortable. I would wear ear plugs or defenders but at some parties it's by far the most comfortable and safe place to sleep.
me so horny, me love you long throw.

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.

Is there a reason for that tantalising pic of the Terra Horn bitoec?
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?
 
really? thats interesting
The EM hasn't got that empty void inside the cab though has it?Confused
 
Still loving that Terra Horn, still my favourite
 
have you or minimaxil got a 1w1m spl graph we can look at for the Terra horn?
 
have you heard the EM quake Biotec, if so how do you compare it to the Terra Horn?
 
what's the terra horn ? i never heard about it ? is it a diy subhorn ?
same question for quake Biotec ?
 
the picture you put ,is from wich opus-audio sub's cab ?
i talk about this picture:

this bin is not THAT big! 950 x 1200 x 546?
can we have a little more info on this? graphs?
 
112db is on par with the Martin ASX, and thats a 21'' 
 
I love that RCF driver by the way, if it the same one that in the dB tech 2 x 18 bins that is
 
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:
