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 ...

[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...

[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]

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...

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 ...

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 ...

[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....

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 ...

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

now but there are some topological ...

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="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...

Yes, it is certain in what I proposed there is majored disadvantage of having a suspended floor. A suspended is like a bad turntable – no matter what you do you would never be able to get proper lower octave. The idea to have horn firing from ro...

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...

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...
