Romy, do you think there is enough of a chance Fane's new studio 5 incher (http://www.fane-acoustics.com/pdfs/Studio_5M.pdf) could be driven down far enough to be worth trying out for an upper midbass horn (120Hz)? ...

Malinowski , are you still around? Did you get into making those midbass horns and if yes how did they turn out? Let me know .Regards, Klamecki...

Probably not one subject among horn enthusiasts does not arouse as much fantasies as midbass horns. This subject in one way or another was discussed at my site (look for the linked threads) but I would light look at the subject of the Midbass ho...

I have been running around this design for a couple of months...I re-designed it just now to change some numbers according to your post. The main idea is to have a lot of posibilities in a huge horn:It is formed by conical sectors th...

Here is an idea that I partially like. I make the horn “invisible” by using a full height of a room; I made just 12” as an example.
This is basically the regular J-horns but it is INVERTED and has a few advantages over what peop...

Thinking further about my "Hanging" inverted Midbass J-horn presented above I asked myself: where is to cut this 12’-13’ horn hypothetic horn. Initially I thought to do it in order to keep the parts smaller to be able to fit them through the doors an...

Of cause it shall be mentioned in the context of thin there that there is always the ALE Acoustic solution. The Japanese ALE Acoustic make two midbass drivers: P1260 and P160.

One advantage of the use of a phase plug in a midbass horn is that it will beam less at higher frequenzies than a horn without phase plug. If the phase plug is designed for the specific horn and driver it will help "steer" the HF.
Me and a friend ...

Dear Romy,
well the horns are actually not designed for HF. The intended working range is up to 5-700. But since we use low Q, only second order filters we want to have a rather large overlap in the crossover region and a fairly even pattern over ...

Let me tell you a bit about how an why we designed the midbass horns the way we did.A few years ago we discovered the tractrix horn for MF use. It was really the most important improvement so far. No more honking exponential horn sound.The improvemen...

Hi Cat[quote user="Romy the Cat"] However, here is where the trick begins. Putting the headphones on, playing them along with the big loudspeakers system and adjusting the volume of the “big system” (primary the LF channel) it is possible to take the...

Wify was asking me about my ideas about midbass horns at one
nice property that we looked. Her innocent question made me to think. I do look
at my prospective listening room from point of view of introducing midbass
horns. I am not planning to mak...

You have said that you want to keep the channel relatively small, and sealed is one way to do it. I don't know your Vitavox, but a larger ("IB") box might have more of the dynamic transcience you mention, and it probably would not be a step back in ...

This is very interesting subject.
I expect that tghe new Midbass horns will have somewhere 108dB sensitively anechoicly. The driver is 99dB and the hyperbolic curve has much more EQ then Tractrix and that is more important the EQ that work mu...

[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 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="jessie.dazzle"]….. sit back and conclude that, yes, damn it, a pair of good straight Mid-Bass horns is exactly what you need. My reasons are of course somewhat selfish... as I won't like being alone in needing a non-digital delay solutio...

Ulf, are you still around?
I would be interested in an update on this project.. are you listening to this setup a year later?
I have a pair of these same drivers (TAD tm-1201) sitting new in boxes and trying to determine what horn profile, tractr...

Dear Malinowski,
Here are the input data used in the HornResp simulation for the tractrix midbass.This is a 117cm long tractrix horn with the TD-1201. Throat area 84 cm2, mouth 10000cm2 with 5,6 liters back cavity.Ang: 1Pi; FTA 89,80; S1 84;...

Dear Malinowski,The basic idea for phase plugs is that the sound from all points of the diaphragm should arrive to the throat at the same time. For the midbass horn we only used a simple one slit plug. If you feel up to it you could make a more...

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...

I still remember proposed solution for symetrical TAD 1201 horn loaded midbass sections. Was it to free listener from sweet spot low seat position ? I could imagine that that midbass horn performing up to 1000Hz sitting low on the floor would impair&...

|
[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="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...

I really notice the absence of any discussion of the melody range. Tannoy tweeter and red midbass seem to be getting all of the attention. I wonder if the reds problem with loud, may be located in the melody range. The problem is something I would pr...

is the compression driver problem not solved by using multiple drivers all feeding into the same, relatively large throat, eg four 2.5 inch drivers into a 5 inch throat? The idea is that sensitivity to reactance will be much less at lower excursions,...

My work to make the Fane S 8m work, continues amd I have yet to hear my midbasshorn built perferctly according to Romy-specifications. I will continue because in early trials there was something I did like. I guess I will just end up with a measly €...

You said are lucky to get hornloading down to 150Hz. Then I guess you suggest you will end up at maybe 175Hz. Hornloading a compression driver down to 175Hz is not too difficult and the horn will not be larger than the Avantgarde Trio midbass horn, a...

Turns out we were in agreement in 2009: http://www.romyhome.com/Forums/ShowPost.aspx?PageIndex=2&postID=11289#11289Have you changed your mind about such a horn that you propose, or do you have any more hints before I build it? Here is a nice exam...
