[quote user="serenechaos"] "I think the ultimate length of the upperbass horn is 3”- 4” throat. With longer horn it would be very complicated to time-align it as the horn will mask out the MF driver."
Is this also why you use tractrix curve f...

[quote user="Romy the Cat"] To my huge surprise and pleasure my midbass horn has absolutely no honk. I heard bass honk in ANY, even the best midbass horns that I heard (BTW, some honk does not bothers me and I even consider it desirable). [/quote] T...

This there is the last in the “THE PROBLEMS WITH HORNS” cycle. The previous threads might be found at:
Problems with horns: tweeters.Problems with horns: mid-range horns.Problems with horns: mid-range drivers.
This would be probably the most contro...

Yes, it turned out to be the emails from GOTO importer. I am not completely understood if the horn at the picture above is an official GOTO product. The Ming Su said that the horn was build locally by Jeffrey Jackson with the support of GOTO but then...

[quote user="jessie.dazzle"]Wow, 6 x 15" drivers (!!!); though the curved profile certainly imparts rigidity, I'm guessing this horn must resonate more than a bit (no bracing until the mouth) -- but I like this thing.
Interesting, the phase plug-lik...

Jessie’s comments about my idea to position midbass straight horns from basement, upper- firing and his warning that the horn will get converted into a giant garbage can made me to think. I did not think about it but it is a reasonable concern. Hypo...

Since I started this thread I have received a number of emails from people bitching that I do not like this, criticize that and that they can’t figure out what I do like. I reply to them invariably – “Do not read my site as you are too much a Mor...

Hi Gera"Has anyone done this and what were the observations of comparing different topologies."I have done just what you propose, I tried the JBL2490 compresion driver with a 3" mouth in a 110 hz horn well made, MDF round tactrix horn, it goes ...

First I want to say "Hello" to our host and to the other guests here.Sorry that I interfere here, but talking about PA inspiration and using PA parts in creative mode in dinning room, I can say that for about 15 years back I was starting my interest ...

[quote user="Romy the Cat"] Ok, I do officially like this “Battle Road” hours. Upon many considerations (and there are 4 ways to implement the midbass horn in that room) I have inclined to my leading idea to do it elegant and with time alignment....

Looking that my attic place is very much triangle I am contemplating an experiment with triangular horn. The idea that lead me there was Balalaika. Balalaika is Russian 3-strings musical instruments that has unique sound. One of the attribute of ...

I realized that this thread is slowly becoming the most sophisticated web recourse about Midbass Horn available. Trying to keep the thread educational I would like to introduce to my readers one more objective of my project. The subject is super ...

This is a very important question as since very beginning of the projects it was questionable if I would be able to get away with the back/top firing position of my midbass horn. So, as now, when the midbass horn project is over and horns fully i...

I just wish before I start my project I read a few detail descriptions of the similar projects. Unfortunately they do not exist and I well understand that my project is in away an exemplary for the horn-minded people. All midbass horn are different a...

[quote user="Romy the Cat"]Yes, they are Fane 24” bass driver with 24Hz primary resonance. I am waiting for the final sound check; the final is long time away. I will be testing today different back chamber size and different drivers. I have a few Al...

I have identified a direction for my next speaker system. Whether it is a good one or not is a different topic -- I think it's a good one because I've lived with my current horn system for 10 years and have since developed an understanding of it's st...

Today a guy I know from south coming to my listening room to hear my payback. He is mingling with horns, he heard my installation in city and he is very much interested to hear my new listening room and the most important my new midbass horn. He actu...

As we are looking for our new home I am slowly simmering in
my mind the ideas about new midbass horns. It is not that I am short for ideas
but I am not sure that I will take my family on a bumpy and costly ride to build
new horns. One way or anoth...

It is so funny. As Kitty and I are looking for different
houses we look at different listening rooms and we have different ways to think
about room sizes. She think about space for her piano and size of oriental ran
she would drop on the floor. Wh...

Oops sorry, I just re-read you post and you did said the “cub feet”. I read it as “sq feet”… so it came from it… If I have 12,000 square feet I would defiantly build a nice sleeping place for my Koshka inside a 50Hz midbass horn… That is one of the r...

Thank you Ulf and Jessie,
I can't wait to get this started. Jessie I am going to send this plaster spec to my supplier and see if I can find something close..
In the past I would use plaster for creating a wax form.. then put the wax form into a s...

A visitor of my site, presumably it is someone from GOTO, sent me email informing that GOTO made a new midbass horn. My enthusiastic applauses to GOTO as former GOTO bass-horns were very bad and not serious.

hello again Romy, cats, friends...
I built this horn for Ming Su, the Goto USA importer... I have posted on your site before about midbass and bass horns... I listen to eight foot straight 45 Hz horns... and as partial payment on this commission ...

"I think the ultimate length of the upperbass horn is 3”- 4” throat. With longer horn it would be very complicated to time-align it as the horn will mask out the MF driver." Is this also why you use tractrix curve for expansion? To shorte...

[quote user="Antonio J"] INTEGRATION that's the clue and that's what I always feel lacks in my room, I mean extreme integration, real integration, the feeling that the recorded bass sound has its own boundaries, not my room's. [/quote]

I got this new midbass horn to replace the Edgar 80Hz straight horn. It is made by Funktion-One and they claim it plays down to 90hz. I could not get it to play below 120Hz and I am trying to figure out why.Pictures are:mouth measurements with no fil...

I've had a long-time desire to replace my Edgar 80hz midbass shells with a better performing solution. My Edgarhorns arrived in 2005, and I made incremental improvements over the years until now they have little in common with the original Edgarhorn...

[quote user="Kcct82"]Thanks Romy, your comment above cleared some of the questions I had regarding 50/60hz midbass horns.
I found some info on the driver after digging through Japanese sites. I don't know if these info will help interpret with...
