The idea of using this type of midbass horn seems good, but I don’t see a solution for time alignment of the horn with the other channels. You have a freedom to physical align it if it is placed in the same vertical plane with upperbass mouth, but th...

A few things I would like to say in context of Pham’s playback.
I will leave his infatuation with turntables alone – man like to collect turntables and he within his constitutional right to do whatever makes him happy. The problem that I see ...

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...

A site visitor sent me emails saying:
“Johan Dreyer says he can hear no time delay with his bass horns…”
Well, first of all I disagree with it. The fact that Johan Dreyer can hear no time delay is not an indication that delay is n...

The folks from lencoheaven.com have a thread where they as most of the people online stupidly damp pictures of different horns, supplementing them with howls “gorgeous” and “beautiful.” One of the installations picked my attention:

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...

I am trying to keep the discussion about midbass horns out of ULF thread, I guess if Rakesh would like he can create a separate thread dedicated to his specific installation and the design ideas. I would like to keep the content of the posts more...

I would like to expose what my intentions are what I was tiling above about Goto 555 or a similar 200Hz driver. My S2 does not stress the bottom of my 183Hz horn. My multi-cell is expositional and those types of horns do pick honk very aggressively ...

+++ Going back in time to your Super Macondo with the midbass horn, I'm wondering how did the big horn influence your perception of Macondo sound if you remember?
Yes, it is very very good question and essentially the question which r...

I was thinking about the throat of my hypothetic midbass horn. This is complex, controversial and it has pretty much no answer, at least in the formeat I ask it. I will share my thoughts with you. Let pretend that I went for exponential midbass profi...

Hello Romy,While you are in test mode, have you played with bath towels around the horn mouth? There's a long thread here by Jack Bouska; you may or may not agree with the content, but interesting how towels make hifi news sound better (if not more t...

One advantage of the use of a phase plug in a midbass horn is that it will beam less at higher frequenzies than a horn without phase plug. If the phase plug is designed for the specific horn and driver it will help "steer" the HF.

I generally like what the Polish people did. Of cause from sonic perspective their system with misaligned tweeters is unacceptable but I very much like how they curved both midbass horn and tweeter fame – very tasteful. Design-wise in this configura...

Despite the fact the I lost the quality of the lower knee of my midbass horn (I guess the primary resonance went all the way down) I keep trying to catch the right termination of midbass low pass filter. I bought those expensive 20H coils and added ...

Below is how my midbass horns feel in my listening room user normal lighting if evening listening. The horn look a bit too dart but they are the same density as the walls in the room. The horns feel darker because the Triangular wall is all white, fr...

That is funny and I kind of forgot how it is. Got home and plugged the SMS digital crossover into the chain of my new midbass horn. I sat to lie different crossover sloped. The bass from the midbass horn was like somebody hit me in face with a wet sp...

[quote user="Jorge"]Now if you design a TH for 70 hz, you can use it from 35 hz up to 140 hz, and that could match up to your 142hz front Upper Bass horn. With this solution you completely eliminate the need for a Folded horn midbass channel, that ...

I got an email from… I do not from whom, somebody from internet. The guy sounds like build his home inhalation and considering some bass horns. He read at my site about my midbass horn project. He was inquiring how my midbass horns sound and if i...

Hello, Ulf.
Interesting. The TAD1201H is 12-incher with resonant frequency of 50Hz. It has relatively low resonant frequency for 100Hz Tractrix midbass but you most like used 10” thought and consequentially shorter horn. The shorter horns beam...

[quote user="Romy the Cat"] A few years back I wrote somewhere that I “developed” a semi-mathematical formula according to which an acoustic system’s result might be absolutely objectively weighed up. I did not go very far with advisement of this eq...

Thanks guys for advice but I have my own view on the subject. The new listing room if it goes through has many very good features that I do appreciate very much. Even the integration of the room with the rest of the house is absolutely perfect, ...

[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...

I stopped by today in a local warehouse and picketed a 4x 16” fiber pipes and 2 two 20”. I absolutely love the effect. As soon I brought the tubes to the room and took the cover off in the hall room turned to be much quieter at HF. I did not expect t...

If there is one thing that I

I think I can imagine how a complex, sophisticated presentation can be too "unnecessarily demanding", in lieu of a better phrase, in a long run in family life circumstances. I sometimes suffer similar problems (I imagine others too).

Romy,Thank you again for a helpful reply. Your comments are very appreciated inspite of not suggesting what to do. I will figure that out myself. And here is what I've learned so far:>> Herman, if you use Precision Devices hen you are at mid-hi...

Jessie, yes from a perspective of general horn propaganda your post it correct but from the perspective of “reading the back side of the midbass speed bump” I would argue that it has nothing to do with horn loading. Look at the notion widely. I would...

[quote user="haralanov"] Romy, the actual sound benefit of this 4-channel upper bass configuration, is rather in the type of sound presentation. The commonly used single upper bass horn (or direct radiator) sitting under the midrange horn, gives the ...

[quote user="noviygera"]I got this new midbass horn to replace the Edgar 80Hz straight horn. It is made by Funktion-One and they claim it plays down to 90hz. I could not get it to play below 120Hz and I am trying to figure out why.
15" driver....
