90% there, I've screwed it all together with no glue to be sure everything fits, and it does. Tomorrow will be glue, mount driver and shake the house day. 😀
An externally hosted image should be here but it was not working when we last tested it.
Awesome, I'll be using a DCX2496 so I'll hook my multimeter up to the speaker outs, and make sure the limiter it set. It does seem like a really nice (and heavy!) driver, and it'll be great to finally hear it in action (it's been sat around for many months. 😱).JLH said:
Gotcha... My amp will do around 900W bridged, but I'll be using a limiter to prevent any toasted voicecoils. 🙂djk said:

Yes, I made Romy's horns. It's not as hard as it looks. You just need to be able to solve problems on the fly, and be very determined. Nothing works right the first time to just please you, you have to make the damn thing work. 😀
Hello zobsky,
what don´t you get?
do you read my double horns and about what,
there you find explanations.

Still Don't Understand
Hello hm:
What you say sounds interesting, but it is not clear. Your english is not clear enough for me to grasp your concepts. Please illustrate with a diagram.

Hello,
please look the measurement of the system,
and below the single simulation,

physically the same as my idea and a smallest study abouit that,

I try to grasp the concept, but the german is as cryptic as the english. Maybe some further explanations could be helpfull for us to understand what you intend. 🙂
One of the earlier TH designs for a LAB12. I have the drivers, my home has a huge open plan room (so no LF gain) and excess is my true path. Once I build the shelves for my books and LPs, the TH because of their small footprint will blend in well. Two of them will be built into the iternal gardens my living room has so will be invisible.MaVo said:
Do you think 3kW is enough power for them?
Not 6 LABhorns, but 6 TH with LAB12 drivers. I agree that 6 LABhorns would compromise the structural integrity of the dwelling.Sabbelbacke said:
Maybe, maybe not. My neighbour hated it when I played my bass through the LABhorns. Slapping E in the best Wooten style would get all her crockery dancing in her kitchen, but it didn't sound 'loud' in my room.MikeHunt79 said:

Sounds like engineering work to me, and I get enough of that all day. I was impressed with the how-to that Angelo(?) posted on his Flickr pages, but not enough to turn up some myself, especially as I'm inot doing horns above LF now.JLH said:
Re: Re: Re: Re: Laying out the wood cuts
Simple answer -- no...
Which is kind of disappointing, since it seems like a pretty fundamental issue when trying to figure out what a tapped horn is capable of, especially for high SPL applications.

Hi HM, i honestly dont understand the text on your website. This is what i said in my first post as well. I have no clue what a "membrane movement cross setting" or a "bass horn mouth distance" are in this application. All i can see are regular back loaded horns for fullrange drivers.
So, if you have a great idea to improve tapped horns, please explain it to us. If you like, do it in german and i will translate, as long its no book in size.
Hallo,
Mavo,
gerne, erkläre dem Forum die
Messungen des Kornetts, Erklärung nach der Simu,
vielleicht die Simu IMP und Frequenzgang an den realen Messungen, dazu die Hornmünder in Relation.
Die Membranbewegungsverschränkung an den
Membranbewegungen der Einzelsimu,
siehe dazu auch die Konstruktionen
Posaune, Saxophone, Trombone alle physikalisch "gleich",
dann dazu das Minibasshorn in zwei Teilen,
das dann auf zwei tapped horns übertragen,
alles gepostet, alles auf meiner Webseite mehrfach
beschrieben, belegt durch Messungen etc.
Solltest du es dann immer noch nicht verstehen,
mail mich lieber direkt an als das du dich..... verschreibst.
dann lies noch mal meine Idee,
und erzähle es uns besser damit es alle verstehen.
"but I have an idea to improve the tapped horns at the low,
~ 1 oktave, and the size, take two ! one ~1,7 m and one ~2,6 m,
place it so the mouths have a distance, IMO 65 cm, but this can
be different, move them, and connect it parallel, the IMP goes
below ~50 Hz flat 4Ohm, and don´t laugh, the short horn makes
more SPL below 40 Hz!
You can get the effect of bass horn mouth distance and
membran movement cross setting, by partial delete ~ 100 Hz
(mouth distance) may be useful up to ~250 Hz."
Mehr als mein Know how kostenfrei zur Verfügung stellen
und das mit Messungen zu belegen kann ich nun wirklich nicht.
Sollte deine praktische und theoretische Kenntnis sich auf
Glauben beziehen denke bitte an F. Nietzsche:
"Glauben heißt nicht wissen wollen, was Wahr ist." ;-)

Hi HM, i think i get a grip on what you do.
You build one enclosure which houses two horns, driven by two drivers, one driver per horn. Those two horns have a different tuning. Both horns are rearloaded / without a closed volume on one side of the membrane. The hornmouths are placed in a certain distance to each other. The drivers are wired parallel and in the same phase. So you get a speaker which is one way, without crossover and has hornloading over a broader frequency range, than a single driver in the same enclosure space could do.
Here are my thoughts on it: Your horns are probably pretty small in bandwidth since they are small in size and because of that resemble more a resonant tube than a horn. By using two of this, you achieve a broader frequency range which has some loading. This is probably usefull in a passive one way speaker, as you get more efficiency and still dont need to use a crossover or several amps. Maybe i miss a critical point in the design, but it seems that it brings no benefit for speakers which use crossovers, as one can easily build as much horns for diferent frequency ranges as one likes.

leider nicht ganz vollständig trotzdem danke für den Versuch,
Vielleicht versuchst du es auch nur mit der Flankensteilheit
der Messung des Mundes des kurzen Horns, was passiert da und warum im Vergleich zur Einzelsimu?

Do you assume that there is a beneficial interaction between the two horns, besides the addition/cancellation of the sound from both sources?
i think so,
normally the short horn goes in the
(sorry) akustischen Kurzschluss you
see on the single simulation, but real system
measurement shows a bass bigger as the long
horn below 40 Hz, it is a 4 Ohm effekt, at the lowest
oktave you eliminate the reso imp, look in comparison
a single simulated imp of a tapped horn.
+
the parallel wiring may contol the stroke of the short horn by the driver of the long horn, so it does add SPL, what single driven not happend. Lower system movement, the step response of the Saxophon is better as can be!! , and i saw a lot of single 8" driver.
only if less large "change press ", (linearized stroke)which again
the mechanical Membrane charges minimized and so
Sound and SPL maximized.
P.S. i would test two tapped back to back in a corner,
mouth distance is "OK", corner loading, indirect sound.
wave length > 3,4 m- 20 m, listenable after the 4 wave,
ear brain system, so 40 Hz ~8,5 m, is 34 m on the run
before you get it, take this in relation to the dimension of your listening room.

say i wanted to build the 30hz horn the same as mikehunt, if i chose the right driver and added some lose stuffing along line, would it work as if the line was longer and get me down to 20hz? is is possible, im guessing it may filter the higher bass frequency slightly, but this may all fit together, even 25hz would be ok
if that doesn't work i would like to convert mavo's simulation for the lab 12 horn, into a atual design that will fit in my room, 220cm would be the max hight allowance, been sitting on this a while, i really want to get cracking now
