[quote user="haralanov"]Actually I see the biggest benefit (besides the huge sound body) in the fact that such a configuration allows very precise adjustment of the way how the harmonics of each UB channels touch the midrange, by simply dealing with...
|
The “best midrange comes from compression drivers”. I see somebody like Haralanov would be very much opposed to this comment. The irony is that I would be opposed as well to this comment. I would say that the best midrange at over 107dB sensitiv...

[quote user="Jorge"]I guess you cannot say you listened to a horn system if you dont have an upper bass horn. [/quote]Yes, I can very much concur with it. The upperbass and MF horns set the frame of the sound, sort of sonic skeleton upon which everyt...

[quote user="jessie.dazzle"]As for balancing the amplitude between channels by driving them from different taps: I drive the upper bass horns form the 16 Ohm taps, and everything else from the 8 Ohm taps. An 8 Ohm versoin of the upper-bass driver...

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="anthony"]Romy, I
appreciate that this is an old thread now and that you may not remember
everything from your time developing these amplifiers, but I have a (hopefully)
simple question about the upperbass crossover in the schematic ab...

[quote user="Romy the Cat"]The biggest problem that usually people face when they listen the middbas horn is that people tend to make the middbas horns too short. In the short horn the driver shot right through the horn and the LF go not “get loaded”...
|
slowmotion,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. The ultimate driver for upperbass should be a compression dri...

[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="Axel"] I hope I got this right when going through this long thread with LOTS of information. Did you mention for upper-bass cross-overs Elko’s (electrolytic) only to be your preference? If I have it right, any special preference at a...
|
Come on, Dominik, no one cares about the LeCleach for bass. You might consider slower opening profile: like exponential of hyperbolic. Exponential will give you a bit more horn gain at bottom and hyperbolic will give you even more gain. Hyperbolic wo...

[quote user="Ronnie"]Haven't had sound with this kind of impact here before. It's extremely even throughout the whole room (behind the speakers too), except for the LF. Wonderful![/quote]BTW, Ronnie, did your recent experiments somehow altered the pr...

Very cool, James, it would be very interesting if you put your ears into an investigation of “Ooopsy back chamber.” I was wondering about the A45 Lowther as well. The 125Hz midbass horns that you made, how big the input hole in there? The attempt to ...

Hi, Martin,
As I understand you are the AU guy who makes horns? I heard a lot about you, very welcome, it would be very interesting to hear your experienced…
I agree with you: what I say on the subject to be entirely true. :-) However, talking abou...

Herman,
I am not familiar with your driver and I do not know those horns. It looks like they are 200Hz horns through….
You shall not worry about your horns create any shadow. As I understand you use digital crossovers with your horns and if...

At the beginning of this thread I said: “Show to me your middbas solution and I will tell you how your playback sounds”. Continuing to stress the domination importance of middbas-upperbass I would like to bring some illustrations and let you to make ...
|
I’ve been harassing my horn-maker for quite a while with an idea to go for straight, no-cheating 45-50Hx horn. We discussed it countless times and sometime probably we would go for this, and particularly if I figure out how to resolve the delays prob...
|
Hi Romy, I've been following your progress, it seems that you are drawing some very similar conclusions to what Steve Schell and I have learned. The bass horn has to be the proper size in order to work well, we are having ext...

We, horn people, when we see as some kind of horn outsider begin to spill his foolishness about the horns inhalations, we always feel that out territory was violated by a primitive brain who listen a box loudspeaker. The Absolute Sound, in its ...

This is funny and depressing at the same time. Two readers of my site sent me unhappy emails informing me that my latest posts” “A typical upperbass horn mistake.” was juts my foolishness. Whatever they said boils down to following:
1) They do...

Romy,If making a Tractrix Horn to cover between 100Hz & 1000Hz do you have to choose an Fc or mouth size that equates to 50 Hz? I've often read, and don't know if its true, that tractrix horns actually need to have their Fc an octave lower t...
|
Bass is what bass is and no mater how greedy audio people become with their implementations bass does not appear to obey people’s greed and lives according to own rules. I always said “if you can not do bass properly then do not do it at all”. It is ...

I am keep listening my just two channels: MF + upperbass. They sound good and I know this sound VERY well but there is one phenomena that I can’t explained/ in the old room my upperbass went to 95Hz-100Hz. In this new room it doe 140Hz BUT subjec...

When many of your will experiment with building and listening your own horns and spend countless amount of time by sketching a configuration of your new horn assembly you then might come to an observation that Macondo Upperbass topology is very s...
|
First of all we need all to understand that all channels attenuators need only for setting up phase of playback live. When the installations are set up properly then it is all not necessary. Anyhow, if the upperbass has less output then you might use...

[quote user="Kcct82"] There aren't a lot of ready made options for 200-800hz so I chose Goto thinking "oh they are so expensive they must know what they are doing." [/quote]
Yep, there in not a lot of our there in horn universe that care the “primar...
