Thanks for your comments, Romy.Edgarhorns weren't an obvious choice. Many horns never worked for me. The Avantgardes left me cold. So did the single-driver crowd (I just don't get it....), Altec VOTs, PA systems, etc. But there were some systems ...

[quote user="jessie.dazzle"] There may be better drivers out there, but with my level of experience, I doubt my abilities to recognize them. So though it may resemble laziness on my part (remember, this is the same person that will be constructing a ...

[quote user="Kerry Brown"] Bruce says his folded upper bass horns work much better though - and he's usually right...[/quote]Well, let do not contaminate ourselves with superficiality. If Bruce suggests that his folded upper bass horns works better t...

[quote user="TonyB"]Romy, what are horn flare frequencies of your horns? I understand that both are Tractrix. My guess is that the midbass is 125Hz with a sealed rear chamber and 4" throat. Correct? [/quote]They tunes for 115Hz and pushed in room dow...

"The top response of the upperbass channel is challenged. I do not know why it is – a wrong driver, a wrong curve in J-horn or wrong made filter… "
That sweep mirrors what I hear - specifically tepid and weak upper bass in the presence region betw...

[quote user="Vasyachkin"]has anybody tried a horn speaker with a dipole bass section ?[/quote]Well, I must say that I have tried dipole bass in a few configurations, including dipole bass plus horn, however I think this is completely immaterial to th...

I except suggestions and critique. I live in Turkey and I am not living in a city, I live at the coast. It is not possible for me to go and experience most of the stuff first hand. There is no one really interested in horns or have multi-way horn sys...

I was rushing when I made the last post. Wanted to share a little more about my thought process and how I arrived at doing another large-scale masochistic audio project. Making a bass horn is a huge risk - the results can vary from exceeding expect...

Quotes from Romy in blue: "...Anyhow, I do not know at which stage your project is what I think you are somewhere in a process of integrating the drivers..."I would like to stabilize the system, and listen to the existing horns, while ...

Merlin, I wonder why you need more information if according to you: “the solution that has not been heard and is not intended for your ears”. You migration from sightless denial to desire of self-education is very… I would say fast but st...

[quote user="Romy the Cat"]
Drdna, generally I would not agree that your assessment of the EdgarHorns is correct. There is nothing fundamentally wrong in them that would prevent them to "disappear" in the room. [/quote]Well, this is good news.&nbs...

When you say, your horns are 11feet apart, does this mean from acoustic centre line, or the outside perimeter of the upper bass horn. If it is from the outside perimeter of the upper bass horn you are having a similar setup with mine. When they are a...

[quote user="Romy the Cat"]I do not understand what does it mean. Are you saying
that you lost bottom response with closed exit hole on the driver back? If with
the closed drift from back you have a (loaded!) response no lower than 200Hz then it i...

Hi Greg,linkSearch the site and you'll find that Ulf has created a upper bass horn using the aforementioned TAD 1201's.I also own a pair still in boxes waiting for the weather to warm up enough for me to start some enclosures and horns for.My origina...

Angelo, I do not think this site add anything applied to the subject. I personally do not feel that upper bass horns require any phase plugs; quite in contrary they are dreadful for upper bass horns. When a straight horn employed then the horn does n...

Skushino. Yes TH is designed to play 2 octaves and no more, this derives from the design which actually uses a labrynth, in the shape of a horn, to return (and amplify) the back wave of the driver to the front and add its strenght to the output, no...

[quote user="skushino"]Have you considered the opportunity of raising your upper bass HP crossover? How high do you plan to use your mid bass horns? If your mid bass is comfortable playing up to 280hz (or whatever the right freq is), you can use yo...

[quote user="Joe Roberts"] The L-9 enclosures were wood on all sides. Sealed box. No ambiguity here.Wings were common on theater speakers for mid-bass reinforcement. Plainly audible improvement on these and, for example, A-7/A-5 VOTs. It is equivalen...

[quote user="Murataltuev"] Now it is
clear! Thank you, Romy!Today I auditioned and measured GOTO with closed hole in
back chamber. Mid-bass completely disappeared!
With closed back chamber it works efficiently
only from 200Hz! So, I'm going to tr...

[quote user="haralanov"]Ironically or not, I have no practical problems with it, simply because I’m not using big UB horns. My upper bass channels are much more compact – 4 very massive 15” drivers with no horns. Their integration to my main widerang...

This gentleman's set-up makes me think very much of the one I have in mind for my new room in due course. Whilst as Romy points out, the room might well be on the small side, it has a very high ceiling (say 4.5 m) that in my mind always presents fabu...

[quote user="rdrysdale"] The bass driver will play to about 8 khz… [/quote]
OK, this dose make some since, become I understood you that it droops after 300Hz.
I wonder what made you to select the 300Hz as a crossover point – the currently existing...

Would not a 9ft-11ft long bass horn path (tapped horn or any horns) cause a sonic problem if not physically time aligned with the upper bass or mid bass channel? The only way to fix that would be to place the bass horn 9-11ft closer TO YOU than other...

We have two models with different upper bass horns, one is indeed a 140hz horn (77 cm diameter) and the original, bigger horn at 110 hz (92 cm diameter) Both tactrix both made from the same materials (MDF) and finished in the same automotive finish.T...

In reference to:

I had recently a guy in my listening room and he asked me if it would be possible to get the 300Hz range in the way how it sounds in my room but without using those larger uppe...

Murat,
I am not qualified to talk credibly
about Tapped Horns. I know that they get a lot of traction now around audio
people but I am, without listening a good example of it, am not so warm to the Tapped
Horn idea. The comments of yours that y...

[quote user="haralanov"] Romy, the actual sound benefit of this 4-channel upper bass configuration, is rather in the type of sound presentation. The commonly used single upper bass horn (or direct radiator) sitting under the midrange horn, gives the ...
