[quote user="Romy the Cat"]With lower then rate frequency Fs is also

Romy,
The upper bass horn has a Ceramic driver 18sound 8M400, the MF horn has an 18sound 2060A Neodymium magnet, tweeter is Beyma Ceramic driver and supertweeter is Fostex Alnico. The Leak amps are PP deep class A, we do have a...

My current speakers are Edgarhorns with the straight 80hz upper-bass shell. The bass never sounded correct to me. The problems with Edgar's mid-bass are well documented at this site and elsewhere. I tried some simple modifications to the crossover...
|
[quote user="drdna"] Now I have had the EdgarHorns in my system for a number of weeks and have been moving them around the room and moving things in the room around to make them sound their best. [/quote]
If you are not familiar with horns then it u...

Romy's quotes in blue:Daniel J. Plach's quote in green:"...The back chamber mechanism is good. Are you planning to do the same in the midbass horn?..."Yes, it will be similar, but more robust; I have an idea for a locking-type seal, which I would pro...

Jessie, I pulled posts from Macondo Axioms thread and encapsulated them onto a new thread dedicated explicitly to your project. I hope you do not mind.
[quote user="jessie.dazzle"] This would impose a design that is not round but octagonal. It would...

[quote user="Jeffrey Jackson"] Also, I had never dreamed of a driver with a variable compliance resulting in a variable free air resonance... such a toy would be wonderful with custom midbass and bass horns... [/quote]
It is why I use cone drivers f...

axioms are breaking with using GOTO 146 with 4" exit in say 150Hz Tractix
?Why you don't recomment to do it ? [/quote]
Of cause not but did you read and understand the Macondo
Axioms? The Macondo Axioms p...

Danvprod, I hope you understand that “proper four or five-way system” is some kind of Unicornnish type of animal and we could talk about it only abstractly. Still, since you have mentioned it – what and how are you trying to accomplish with your five...

[quote user="speedysteve"]I have found
that 8th order X/O works best with them and I cross at 90Hz these days.
4th order is ok but you get minor colourations and some bleed through
that just aren't a distraction on 8th order. The bass horn takes ...
|
Well, yes... I've not been to prison in over two years! Apart from keeping me off the streets at night, the results when listening to one of the 40Hz horns were, dare I say, encouraging, though I do hesitate to say so, as the "evaluation" was carried...

How Wilson sounds:Pressure caused by non-linear bass squeezed through narrow port holes.Shining caused by the papery upper mids of a too high crossed 6.5" midwoofer.Sparkle caused by the metal ringing of a titanium tweeter.What Wilson does:Use st...

[quote user="msaudio"] Every frequency above 80 cycle's should be coming from the front of your listering position, next to macondo. [/quote]thats correct the worse thing you can ever do there would be trying to get your upper bass 80hz above from t...
|
Yes, I know it is not correct to make any generalizations and it all depends upon the acoustic environment, where the horn is being placed and the influence of the other channels, so my original question was in context of listening to the upperbass h...

So, you use DCX 2496 for deals but not for crossovering and your crossovers are still on analog domain, right? Romy, I do everything in the digital domain so I use DCX 2496 as my crossover as well (but analog SS pro amps). I know you're no big fan of...

Hi, Tim. This is difficult question, and it is difficult in it’s abstractivnes. I really do not understand, or understand but refuse to acknowledge the validity of the word “respectable”. How valid for YOU would be a “reputation” of this driver if it...

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...

I made today some interesting experiment and for the first time during my “fundamentals channel saga” I get some stimulating and very result. I find a way to mount the “low frequencied S2 driver” on the speaker’s axe way above the Macondo’s tweeter. ...

Well, I loved, loved it loved it… but today I decided to experiment with integration the new horn into the system and learned that it would be far much complicated and take more efforts. Below are 3 sweeps form listening position, Firs is the new hor...

Hello Romy,Thanks for the great explanation, I'm a newcomer to horns, so please treat me gently ;-)Very interesting info, so in essence there are two limits, the real "hard" limit, where you risk damage to the driver, and the "sensible" limit, below ...

Loudspeakers. For whomever who follows my dairies on this site and whoever has any real understanding what makes a horn-loaded loudspeaker to sound good it is know that Macondo Acoustic System is not juts the result of my DIY efforts or the John Hasq...

Once again, let make it the last post off the subject of the 5-chals Milq.
I think it make sence to start from 370Hz-400Hz horns for S2, targeting it for 1000Hz. Then the lower bass horn, for instance the 45Hz, however it should have a chamber of m...

Marc Henry-In the 6moons write-up, you mentioned the Altec 515 re-issue not being satisfactory for your purposes on the Grande Castine horn. I presume the specific 515 variant you used was the 'g' type (designed for horn loading) rather than 515'b' ...

Guest napping now from 16 hrs jet lag, so I have a moment...Jorge, you raise an interesting point about THs. I may be incorrect in assuming THs sound worse as they play higher in freq. Perhaps instead the limitation is one of narrow bandwidth rathe...
