Well, that is kind of the end of the little midbass era. As
we begin to prepare the moving in a month I removed the Vitavox driver from
Midbass horns. The even went unnoticed in my family but I have a lot in my hard
to feel about. The new house is...

A few months back a audio guy visited me and after a listening session I asked him if he can report any problems with sound. He reported that he hears a slightly more prolonging decay at upper bass then what he suspect to be. I knew about this effect...

[quote user="Saturntube"] Anyone has some sort of comparison between compression drivers against cone (dynamic) drivers in a this huge mid bass horns, or even upper bass horns. All I heard are this guys from Germany with the out of reach expe...

Jorge, that is good but a few thighs I would like to mention in this approach:
1) What you depict will work with tractrix or conical horn but not hyperbolic curve. The hyperbolic has own “swell” into exponential curve that would make it to...

Sure, I’m very much done with Macondo and the late frame is the last straw that I load to this camel. It took 60-7 years come up with where Macondo is now and I do like how it turned out to be. In a week or so I will be done and I will post the pictu...

[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...

Hi Romy,Well, this is my (and my dad's) first horn system so we're learning/building one step at a time. Our motivation is simple, to use horns as low as possible.The very first DIY configuration was:TAD ET-703TAD 4002GOTO 505TTTAD 1603 Woo...

[quote user="Romy the Cat"]Interesting the stressing the importance of the listening room Rakesh went into depth of discussing reference clocks and YL drivers that are very irrelevant to the subject of the rooms. The Rony’s comment about the expressi...

Rakesh,Thank you for your kind remarks. I appreciate the close scrutiny you have given my previous post but I think you are at a stage of system design where many basics of your system should be considered and evaluated before the issues of my po...

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...

I was thinking and thinking last couple days what to do with
my lower midbass situation. I do need to use 2 drivers per channel with 100dB efficiency
to get the dBs I need to match Macondo and Milq’s bass channel gain. I do want to use Vitavox 15”...

[quote user="noviygera"]1. Let's say
the my original back chamber from the manufacturer is a good "starting
point". Is Romy saying that those last few hertz of the fine tuning of the
chamber volume are very important and audible, in other words th...

I was wondering what would I say or do with my house-build in horns if I move from this home? No, no not, the horror of married life that audio people love to tell to each other are very much not applied to me. There is no problem with computability ...

Looking at different properties and trying to in my mind to arrange the setting in my new listening room I have concluded the absolute minimum dimensions of the room. In case the midbass horns are NOT in the room, the room has over 12” or a cathe...

Paul, I do not care about dusts. I coved what need to be coved about the rest…. I do not care. The building of midbass - is a final stage of my moving and ….unpacking. So, I did not put any “vulnerable” furniture in the house as I knew that the midba...

[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...

[quote user="Jeffrey Jackson"] so, my straight horns... I like them very much.. I built mine similar in style to what Greg B linked, but obviously much smaller.. mine are just under eight feet long (length of a sheet of plywood) and have a mouth roug...

John, I am bit puzzled with your response. I do not know what would be a proper material for cone/dome of diaphragm. The source where “tone” is born in compression drivers is absolute mystery to me and I in my holly naiveté believe that no one else k...

First off, the crossover point will be 530 to 600Hz. the RES 1.5 midhigh is 16" x 8" x 10" deep.Keeping in mind, I'm trying to cover 600Hz and below... Given space constraints of a medium size basement room, I came up with 2 options.1st option is to ...

Here is another installation where midbass horns are ceiling-mounted. The solution is very elegant but I do not completely agree with it. One of the rules of the game is that lower frequencies shall not be radiated from the space between higher frequ...

[quote user="Macman"] Anyways, seeing the back chamber of my midbass horn, you would say that its way to big, no? [/quote] It is very hard to say. You need to measure and to publish the resonance frequency of your loaded driver and view it in context...

Ok, Andrew, this is allergy something. I would highly advise you in future before you post any discrete updates, questions, and ideas about what you to inform about the holistic objective of your project, sort of a view from 50.000 feet. That what I ...

Rakesh, I think you’re doing a strategic mistake. You see, there is no manual in those things. As much as you are trying to come up with one it still will be no manual in the end. Reading this site one might think that by venture of my site I have bu...
