[quote user="Murataltuev"]Is any
technical background behind the statement that 4" driver can't
operate in 300-1000Hz because resonance is too low ? [/quote]
Well, you need to define what does it mean “can't operate”? Anything can operate anywhere...

I think it's already too late for that. A man should not go around and listen to stupid horn installations which can screw him up for a life 0).Robert , can you say why 65Hz truncated tractrix and not rectangular half space hypex or expo horns if you...

Hi, can you tell me(us) how much you pay'd for the mid-bass horn please? I may try this myself as I have been waiting six years now for a 15" midbass horn plan that is suitable with no luck ...thanksr weissmanps. Oh sorry I just found the price pa...

Ok, it is not my mouth but the mouth of my midbass horn. It is 1:1 calculated size of 43.5Hz and we measure it against the opening space in attic, It fits perfectly and it has at least 35 feet behind for the horn neck. So, far so good…....

[quote user="jamikl"] My problem is the length of a mid bass horn and I can see no way of doing it other than bending it in a curve or mounting it down facing to the floor as in one you showed, or goingclosed box which I don't really want to do. I t...

[quote user="noviygera"]Number one, that I'd like to run by you guys due to it's simpler nature and closer to reality execution is the idea I have been thinking about. No first hand experience with any of this.Say we use something like altec 1505b mu...

[quote user="msaudio"]Putting The Mid Bass horns behind your head will not work. This thread was about Mid Bass Horns Project, do you thank you will be able to use any frequency above 80 cycles with rear fired horns that are behind your head? Tha...

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...

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.
Me and a friend ...

Then i have problems with my tapped horn. He works 25-90hz range.What you recommending for bass or midbass?I do not have too much room for bigger horn system....

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...

+++ 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...

[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 ...

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...

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...

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.

[quote user="Romy the Cat"] In fact I do feel that
my MF and upperbass are very good integrated. But again, I might not know how
different it might be if it was otherwise. [/quote]
Exactly!
Some time ago I also thought my upper bass channel is ...

Now I have been listening the different crossovers trying to shape the new Macondo general balance. This is so fascinating ceremony that I do have a lot of fan. The things doing alone very well. I boosted upper bass and it worked now very-very well....

If there is one thing that I
have learned in life, and heard many times, is that making a mistake is
not a bad thing if you learn from it. In addition the lesson learned is just as
valuable if you learned it from som...

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).

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, ...

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...

[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...

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...
