Hello,
tell us the similarity to my double horns please

The fact that your "horns" have double mouths does not change anything. You are trying to compensate the irregularities of the response using differently tuned pipes but the end result is the only thing that counts. I see only double efforts to suppress something that is mistaken by default. Good luck with that - you use to try construction with 22 different mouths :-)))

expensiv driver which will at least worth for the money.
And i found a lot of driver which are after 300 ours good enough.

If you really believe this it is nothing than a clear indication of you low sonic demands...
BTW, which are those drivers and why do you think they are good only because they are expensive:-))

Stupid!??

Hey boy,
is it a kindergarten,
"does not change anything"
you don´t understand my construktion, your are not able to interpret measurements and simulation,
if you are so blind, to see and understand,
why do you post, little boy.

it is so boring. read again show us single driver measurements and IMP and compaire it:

Through membrane movement interlacing there are more bass, due to the bass
horn mouth distance, there's no rise above 100 Hz. So the pressure chamber can
be kept extremely small, both horns are extremely small. Small is also the air mass
in the horn and the wall-to-wall distance inside the horn is short, the relatively
small cabinets also contributes to the fast, contoured bass reproduction.

An attempt to explain
these graphs:

By way of parallel
operation of the two
different horns,  the
driver of the long horn
controls the stroke of
the driver in the short
horn. The little horn
will not be acoustic short
circuited,  but instead
creates sound pressure,
amazingly much, more
pressure than the long
horn below 40 Hz.

At the same time, the
impedance peak of the
lowest octave is eliminated
by non-interlacing,
below 50 Hz~4 Ohm.

See system horn mouth
measurement and single
simulation of the
CORNET and impedanz.

Membran movement
interlacing:

My haptic verifications
show a rather linear
membrane movement,
similar to a normal
distribution curve.
Which means a reduction
of "pressure changes",
and hence less mechanical
membrane stress and
maximized

Stupid or not - the sound remains the same - just bad sound
fiogf49gjkf0d
Moreart, believe me or not, but I perfectly understand your constructions – they are nothing more than a simple reflection of your own way of thinking about audio and sound - just a pile of glued wooden panels without any audio based motivation behind it. Do you want to achieve specific sound out of your horns or you just try different methods to see what will happen? Following your logic and complete absence of any audio motivations, you may tattoo a middle finger on the whizzer cone of your drivers, telling everyone they sound much more better. Back loaded "horns" like these has sound signature which cannot be mistaken even if you listen them at the next room with your back pointing to them. All of the music sound exactly the same in the zone of mid and upperbass and after 15 minutes of  listening it becomes very very boring. You insist the Moon is made of chocolate, but it doesn't change nothing - these constructions will never sound like properly made horn. I do not understand people like you which are looking for agreement but they are not able to handle some critics. You are not the first who react this way and of course you will not be the last. Post your projects at diyaudio.com , show them the measurements and everyone will tell you the words you want to hear. Good luck.

Oh boys
fiogf49gjkf0d
oh boys may be your brain is made of chocolate,
good luck,

Markus, very poor,
only a quote, good luck.

and romy is out because he didn´t find
a similar construction he will have heard?

What a forum.

The “phantom fundamental” BS idea.
fiogf49gjkf0d
Haralanov, do not write stupid posts, you have “no experience and no knowledge” about it. Also, do not propose to look at any other speakers as looking is very a deceptive activity. There is a phenomenon of vision that called “phantom visual reality”. It implies that if object is not there but if it very much wanted to be there then the existence of object considered actual.  It like if you crave turkey sandwich, you have no sandwich but your stomach have produced the acid to consume the sandwich then the sandwich is consider eaten.  You, Haralanov, with your “limited experience” do not know how to yank your left ear in order your digestion system created the right acid trigger the effect phantom perception. You in your ultimate ignorance are running around a yard, trying to catch a turkey, kill it, cook it and make a sandwich from it. Moreart is much more sophisticated - he does not bother with cooking turkey or knowing how to do it.  He knows however that a turkey will eventually get converted into bowel movement and he is trying to mimic the after-turkey bowel movement in order to convince a gourmet eater that a phantom turkey sandwich was delicious….

Moreart, you have a strange and wrong vision of interaction protocol at this site. There is no community in here what you need to convince in anything. People in here are on their own and they care only about themselves and own results. Whatever you do you do for yourself only – you feel yourself a bellybutton of Universe – good for you, trust me, no one cares. You did post the explanation how your speaker works. You have push-pull horns and one horn does something to another. It is elegant but it is irrelevant.  The effect you get might be described by LCR resonating chain? It was done zillion times. Regardless what you say your horns are “DIY Pipes” and it is very irrelevant what you do with resonating of damping of drivers. Do you understand that the driver I and ANY behavior of the driver in the topology of your horns is irrelevant?

BTW, if you would like to talk then can you tell me how your speaker sounds in compare if it were not using the “phantom fundamental” BS idea. Oh, BTW, why from your experienced point of view the musical instruments are not being made utilizing the “phantom fundamentals” concept? Would it be great to have a flute that produce impact of tuba and to have a fiddle that would make Giovanni Bottesini to feel that lived his live meaninglessly.

sorry your post is irrelevant,
a little bit psychotic,
where is your list of horns which work like mine?

please delete me, i bet for it.

Go with peace….
fiogf49gjkf0d
Moreart, if you ask my opinion then let me to decide what is relevant. Your idea of “how” your horn work is self-delusional in my view as whatever you imagine you do go overridden by deficiency of your mouths and by other problems that your enclosure has. You would argue that your measurement do not show it and this is why I ask how your horn sound.  You feel that it is irrelevant – which is fine. I accustom that each person who stress DIY treat question about sounds as irrelevant personal insult. Your measurements are irrelevant unless you understand how they related to auditable experiences. I do not know if you do but I know that you bail out what you asked about sound of your speakers. If you fart in your microphone then if will show some acoustic pressure – it is completely up to you to recognize the bump as “primary resonance” or as irrelevancy…

Do not beg to delete me. Stop post and no one will bother you. Your manner to shape a defense of your design idea is very unappealing. Of cause the collaboration of audio ideas it is not a beautify context and you perfectly in title to ask in any way you wish but you did not convince me that that I need to review my view about what you do, in fact it made me more confident about my position. Psychotic is what I hear a LOT in sound of you.

"and romy is out because he didn´t find

no he is in, he know nothing,
he can´t look the IMP, not the SPL,
not the range, etc.

and will know how it sounds he is not able to read and
translate the feedbacks on my side.

Through membrane movement interlacing there are more bass, due to the bass
horn mouth distance, there's no rise above 100 Hz. So the pressure chamber can

be kept extremely small, both horns are extremely small. Small is also the air mass
in the horn and the wall-to-wall distance inside the horn is short, the relatively
small cabinets also contributes to the fast, contoured bass reproduction.

i think it is for your person and the forum not a good idea to delete me not.

everyone can read your disqualification,
and you can lie like a trooper.

I think this must be enough to be deleted.

sorry where is this Forum located, in USA?

I take that back. I had decided not to post on this thread anymore, but since so many of the terms you use, Horst, are new to me, I was intrigued to find out if I had been missing anything. So I googled the word "basshornmunddistanz" and found a good number of discussions, like here

 http://www.visaton.de/vb/archive/index.php?t-16764.html

where other people had tried to make sense of your construction and pointed out that your interpretation is wrong.

For example, just looking at the impedance plot you kindly provided, it is obvious that what you have built is indeed a resonating device.

I also found that correspondence with you always follows the same pattern as on this site.

So, again, I wish you luck in your future endeavours.

A BS transmission line with an oversized port vs a Horn.

 I do not think that it is an honest argument. The “other people” is never an argument as it immediately brings the question: who are the people?
 
I did not read what “moreart” said elsewhere beside what he expressed and show at this site. What he has expressed did not make me to be interesting and to read his site.  The problem with Moreart, in my view, is not much different then with many-many other DIY-minded people (whom I hate) - they preocupated with manufacturing of some kind audio without having a rudimental understanding of sound.  Any sane person who has a respect and comprehending to what Sound wants can recognize what a horn does when it overloaded with LF, the LF that mouth can’t pass. The whole Sound got change, the nature of Sound got changed – if a person can’t hear it then he just can’t hear it. Moreart from one side adherents to the BS idea of “phantom bass” but from another side would like to extend bass of your speaker by building some kind active resonator in it. Ridicules, as whatever his resonator would/might do will be anyhow fucked by the undersized mouth of his horn. In fact this type of the horn I do not consider as horn. I considered it an exponential transmission line with an oversized port.

Whow
fiogf49gjkf0d
oh boys,

it is boring,

where are the known and listen construction like my constructions,
you both tell this forum you heard,
show us.

I think you won´t show us, you won´t identified as little liers who don´t understand
simple physics, why don´t you show the forum, the difference or similarities
of your horns.

Who thinks i tell not the truth on my HP must be very stupid,
who don´t understand and write that he did´t read is more than stupid.

Before open your mouth or take the keyboard switch on your brain. 

Romy delete me,
or shall i spam your forum in hell,
" be careful with this Forum the moderator lies"
shall i start?

Ok, moreart, it is official – you are an idiot. Upon your classification your account is suspended. If show up under different account you will lose reading rights on this site. It was no my intention to get rid of you but this fake drama of your “suicide by cap” has begun to annoy me. Good luck with doing what you do.
