[quote user="KS"]Thats the kind of stuff I was hoping for. I appreciate the help with this, there seems to be a scarcity of horn related discussion on the web and its proving hard to learn the ropes.One other unrelated question that could save me a l...

Chris,
The point of digital delay is well taken. Digital has no problems to delay and if someone had only digital as source then it is very simple to use tow parallel DACs and to stick temporary storage memory in one or them. In case of multiple so...

[quote user="jessie.dazzle"] Romy's comments on "axial rotation" of the horns (meaning in this case, angling the horns) has me thinking. I had planned to build in a vertical tilt adjustment for horns located near the floor and ceiling... I woul...

[quote user="Romy the Cat"]I do feel that a playback sound has to be built first...The way how I trained myself is to disconnect channels. While I was making Macondo, installing it, moving it and experimenting with it I was frequently disconnecting c...

Would not a 9ft-11ft long bass horn path (tapped horn or any horns) cause a sonic problem if not physically time aligned with the upper bass or mid bass channel? The only way to fix that would be to place the bass horn 9-11ft closer TO YOU than other...

Hi Romy,How would such a time delay manifest itself in the resulting sound? Have you had the opportunity to listen to such an attempted system? Would the benefits of having a hornloaded AK151 not outweigh this or would it just sound too wrong to...

Hm, your advice to discard the Midbass time alignment and to
go to ULF time delay to catch up with Midbass timing is very interesting. Theoretically
I have no auditable sound from ULF. They are at 20Hz. As you understand there
is no way to align t...

Ok, I like your illustration. Let look into it deeper.
Considering that God located very far from the boat then the individual streams of God’s blows departed from a single infinitely-far located point (the God mouth) are parallel, as it is d...

Johan, I understand what you are saying. This is kind of James’ barn thread and if you do not mind can you share with him one thing, I think that many others, including me, would be interested to learn the answer to this question: What did you gain g...

OK, now I am happier as I did my duty and the back chambers are ready to be attached to the horns and to be lifted up. Yesterday I spent 5 hours trying to build the back chamber displacement that Jessie and my carpenter ...

Romy, make you own very simple experiment and then make your own mind.
Take two horn channels, low-pass and high-pas them at 6K for instance
and drive them with 6K sinewave. When you time alight the driver you
have well ...

Another very interesting aspect of the Water Dropping of Macondo is a dramatization of silences and influence of LF decay. Macondo has no own noise and the Super Milqs are dead quiet. However, the perceptions of silence with the Water Drop tweeter an...

At some point last year, after I had been offered an opportunity to buy some Vitavox S2 drivers from someone in Paris, and some S3s from Germany, I decided to approach Mike Harvey of Octave Audio, AKA Vitavox Hifi, to get some information about how I...

I do suggest to re-read my post above where I stated that Pacific has remarkably similar sound to Bidat. In Bidat there is one quality that sets it apart from any other converters out there – the Bidat’s dynamic bursts are orders of magnitude less an...

I should have said UP or Down in the listening chair. Toward and away from the speakers will also do it, unless you're sitting midway between tweeter and mid of course, but not to the extent of up/down will.I just did an experiment with some fishing ...

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...

It is looking like I will be constructing the 45Hz horn before some of the others. In considering time-alignment I went back through some of our posts and found this :

I think to a degree we misguided with our expectations as we
feel that the answer is in directly heard sound. We attributed to sound some properties
and we evaluating the properties are trying to make judgments about sound. I am

Merlin, I have nothing against Bernings, in fact I found it all educational as I never had exposure to them. Well, perhaps I did hear them at some kind of hi-fi show but just did not paid attention. I hardly believe that I will hear Bernings as I’m l...

Very good, thanks for the images. It would be very interning to learn what the bandwidth of the horns, the bandwidth of the drivers and the specificity of crossovers you eventually chose to use with each channel. It might take for you for a while to ...

Nice posts Romy and Jan, agree almost 100%. I've heard the Behringer in an originally crummy system and it butchered things completely. The input levels were low, which as you point out, won't have helped at all.On a vaguely related note: I dunno if ...

[quote user="jessie.dazzle"] Regarding the Mid-Bass : If these guys are using the main block as a Mid-Bass horn (as Romy's illustration suggests), then the story is getting interesting, and the plot is definitely thickening... It would however seem i...
