I take it back, 100Hz is pushing it regarding horns and compression drivers I know of. I can't imagine a compression driver reaching the midbass muscle of the Fane S 8M. And I don't see why one should try, when the Fane reaches 120Hz so effortlessly....

Tonight I finished two
horns at once. One was a shortened Goto S-150 horn that now has a
Fane S 8M, without back chamber so far. Dimensions are now 1.1m deep, 11cm throat, 75cm mouth. It is replacing the Avantgarde
Trio midbass horn r...

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...

I’m new to this outstanding website and I found it has really educational value and antimoronizating information :)
I’m still in the world of direct radiators and I’m looking for the ultimate midbass channel solution. At this time it’s still impossi...

[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...

[quote user="Romy the Cat"] When I have my old transformer 11:1 then I had the midbass horns calibrated so perfectly that you can tune a large symphonic orchestra by it sound. It was spectacularly stop-on setting with any type of music if played it n...

[quote user="Romy the Cat"]The subject of midbass nasal sound is very interesting. In addition to all OTHER aspects that might lead to midbass honk I would like to note that there is one that is in my view greatly overlooked – the precision of re...

Romy,I might have overlooked something on your site but I understand that your ULF amp is driven directly by the preamp line stage. If that is the case, you may want to consider an old technique for integrating subwoofers and drive your ULF amp w...

From the time of the insertion and setting the proper crossover my midbass is growing and growing, getting larger, deeper and better in all aspects. I am not kidding and now, when I have no ULF channels operational, it is very obvious. I can’t explai...

[quote user="green heron"] I'm happy with my results midrange on up at the moment, but I'd like more slam from the midbass horns. The backchamber may be a bit too large, so I'm planning to experiment with the cabinet volume. Do you have any su...

I need to say that for whatever reasons the midbass horns acts as a phenomenal tranquilizing sedative to listen some older recordings. The midbass horns make bad sound much more palatable and make attention to be much less distracted to quality of ...

[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...

I though this would be answered elsewhere (AA) but Bruce Edgar did not reply. This question is important for me, maybe someone can help.When running an impedance sweep on the Edgar 80Hz horn some serious bumps showed up. (I ran the sweep because it s...

[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...

I just noticed the empty space at the location where your midbass horns are/were positioned. Am I blind or are they missing?Edit: I must be very stupid - the photo is probably taken before they were installed... :-))...

[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...

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...

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...
|
|
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 need to say that with all huge advantages I have in my room with my midbass horns there is something that lost. I lost a great impulse response that I use to have on my old room with my direct radiating bass array covering up to 70Hz. I did not...

I was listening recently my Carl Schuricht’s Bruckner and I again noted what I am been noting for a while. I feel like my Midbass horns begin to sound a bit saggy. It is not too but and the degree of change is very minor. It is not even auditable...
|
|
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...

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;...
