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 ...

[quote user="MINGSU"] The SG146LD4 driver can play down to 20Hz but we choose to crossover the horn at 70Hz only due to the space limitation of my listening room. [/quote]
Ming, here is the whole point. If the driver meant to be play20Hz then ...

Ming,
I was thinking about this SG146LD4 driver again. They say: 106 dB/ 20 - 500 Hz, 19,000. Well, let look at this a little bit further as I feel that might be very interesting driver.
I admit I never heard about this driver. All that I know abo...

"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...

John, I disagree.
No one deny the importance of harmonics and you are right saying that “If a speaker does not reproduce the harmonics correctly, then the tone is not reproduced correctly.” However you are talking about a complete speaker, not...

i am sorry but i cannot answer to all questions, for several reasons you can understand.we have tested many drivers since the early prototype of La Grande Ca...

[quote user="slowmotion"]I'm not so critical as you to open baffles for midbass, tho, in fact I think they can be made to work quite well, if one doesn't have the room for midbasshorns. [/quote]
You suggest that open baffles might be more successful...

[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 do not comp...

Bruce told me last year that he started to manufacture 80Hz straight horns to replace his 80Hz. I was under impression that you refer to it.
Anyhow, if your midbass horn is fine then one of the most effective ways to get it even better is to reduce...

Hi all
The WE 555 is IMHO an interesting driver, made for a very spesific use,
which is driving a "full-range" horn in the theatre.
As we all know, the wide range system with Jensen 18"woofers and Bostwick tweeter came later, at first the 555 an...

[quote user="rdrysdale"]….as of now I'm convinced that a compression driver is the best way to go for fast, detailed and dynamic bass. The compression ratio needs to be just right, and the horn needs to be right, when these two are working together p...
|
|
Romy, You have a most different and refreshing way of understanding and explaining audio, sometimes I have trouble following your discussions, but I find your ideas most intriguing. By fast bass, ...

Here is an image depicting the radiation pattern of the HF for a midbass with and without phase plug. The dotted line represents the HF output. This is not a measured response!Here are a couple of pictures that may be amuzing. My girlfriend and the s...

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...
|

Yes, Jessie I have thought about it as well but whatever you do with 40Hz horn you end up with horn talk with each other. It is very simple to measure – use one as a transducer and put a measuring dB meter across the VC of second driver, treating...

Room looks large and has a lot of potental, i also have simialiar room except no cubby hole on right channel. It would send up an alarm with me with low resonance problems on right channel do from cubby hole, Maybe you could put some type of sliding ...

I set up today the framework in which I will be testing my Vitavox 15 inchers. It is a wooden frame from my bathtub with a driver screws to it, the massive sliding doors that squash the driver from both sides and cardboard that cover the wholes. This...

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 ...

Say whatever you want but some of the vintage drivers has
it. Not all of them but some of them do and the question how to get it. I
always has been an enthusiast of midbass horn and I am very much the enthusiast
now but there are some topological ...

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 ...
|

Romy,I am considering a midbass channel similar to that you are currently using. The plan is to use the channel as a form of EQ to help rectify a large circa 40Hz room mode...bass cannons below the mode, midbass above the mode, and upperbass horn ab...

[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....

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&...

Quick answer before I have to leave for the airport..........
Romy, I agree with you that horns is a better sounding solution,
for myself it's the only way to go.
But only if one have the room for real size midbasshorns.
A lot of people have t...

Don't worry Romy, I know exactly what you mean. I tend to discount the opinion of anyone who raves about a system's ability to play back patricia barber. Speaking of which, if I were in her shoes, bunions and corns aside, I'd be mildly...
