[quote user="serenechaos"] I do not know of importance of enemys death to this topic. [/quote]
Oh, this is a sheer pleasure but do not call that dirt enemy. He is not enemy but way beyond it, he is the person about whom I have a death-wish as ...

Sorry, I do not share your sentiments with those 3 reasons. Below are my reasons.
[quote user="jessie.dazzle"] Three reasons:
1) To try high passing your upper-MF channel (S2 > 400Hz horn) above the 1250Hz secondary resonance assiciated ...

user="Murataltuev"] So, driver for 1200hz down is under
consideration.I'm going to try 2453, 2451, 2490 and Supravox 12" for this
range.I've ordered 200hz LeCleach from AutoTech with 6" throat to try
12" Supravox for the 300-1200hz range.A...

Yes, what you describe completely makes sense. In your case
the upper horn is not what in my systems. Since you have no truly MF channel
but rather upper MF and HF your Fundamental is kind of main source of sound. My
Fundamentals covers from aro...

[quote
user="kodomo"]In my first design, I kept them all in a vertical line.
It had one channel less back then. When I added the 1" throat JMLC 1000, I
decided, as the tweeter operates over 9.6k, the slight misalignment may not
matter. Still, I k...

Rakesh, I think you take it all wrong and I think you need to perform some degaussing from my site. You created for yourself a cardboard cutout of ideas that I describe at my site but it is not what it is. Macondo Axioms are not set of rules but a di...

The last year there was some chatter up about artificially created so called “digital drugs”. If you are not familiar with it get familiar here for instance:

Jacky, so, you are the person who did that presentation at

welcome. Is the same internet forum account used by multiple people then it is
hard to differentiat...

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...

[quote user="Romy the Cat"]I do not understand what does it mean. Are you saying
that you lost bottom response with closed exit hole on the driver back? If with
the closed drift from back you have a (loaded!) response no lower than 200Hz then it i...

[quote user="Macman"]Just realised that I had dual highpass filters on the TH, which more or less cut off frequencies below 50Hz entirely. A lot better now, still much to be made of course.[/quote]
This is very normal. People get the “building...

[quote user="Romy the Cat"] I do not use compression driver
for bass channel. I would like to have my system esthetically balanced, to get let
say 120Hz from a compression driver would take too long horn and it would be no
way time-aligned it. So,...

OK, the new Macondo frame is over as well. Eventually after 6 years of learning how to make the damn horn speaker to sound good, after numerous incremental successes and failures, stupidity and brightness, moves to wrong direction and mistaken assess...

[quote user="Wojtek"]This is probably the reason I can listen to EV Patrician IV in relatively small space and close to the speaker without much of fatigue. The other factor must be that it's 4- way design with narrow band-pass for each horn. E...

Ok, I have been experimenting with placement : Long wall versus short wall. Though the frames have wheels and roll very easily, my room is cursed with an elevated platform smack in the middle of everything (about 14 inches higher than the main floor)...

[quote user="twogoodears"]…. they seem to operate in a very specialized narrow bandwidth... So, my (humble) advice - based on my direct experience - would be: if the case, try to use Goto as 4 ways, not the more common 3 ways... also if Tanaka-san is...

From Email that I got today:
“….. I see that you are considering trying the metal diaphragm again in your S2s. I am using the metal diaphram for the moment (it is all that i have), but have the terrible ringing problem, especially on female vocals. ...

[quote user="drdna"]I was really shocked when I saw this idea of yours. It is a trade off of course with improved control over narrower frequncy bands being traded for axial symmetry. Yet because the position of the drivers is so very imp...

It is difficult to say below what frequency there is no sound registered, the lowest fundamental on a double bass is 41Hz and the A0 on a grand piano is 27Hz, both these fundamentals and at least one harmonic thereof would probably be recognizab...

axioms are breaking with using GOTO 146 with 4" exit in say 150Hz Tractix

Axioms? The Macondo Axioms p...

[quote user="Murataltuev"] Now it is
clear! Thank you, Romy!Today I auditioned and measured GOTO with closed hole in
back chamber. Mid-bass completely disappeared!
With closed back chamber it works efficiently
only from 200Hz! So, I'm going to tr...

the bad result during audio show does not mean anything, only good results
count. You see, there are zillion reason why during the show the sound might be
horrible. The inadequacy of the people ...

Romy,
[quote user="Romy the Cat"] Remind you that horn
not only does that but it performs acoustic transformation gradually. [/quote]
Yes, I do
agree with you about that. From both theoretical and practical point of view it
is 100% true. But...

Ok, I loaded the S3 driver into the new multicells, use my extra of bas sections as a pedestal for multicell, connected 2 extra bass channels to ULF amp and the multicells to full range amps with no crossovers. Yes, I got a VERY good width and th...

I do not think that I changed
opinion about anything. I used the white suspension since my initial introduction
to of S2 and never likes any other suspensions. I do use metal suspension with
S3 driver in my Fundamental channel but is operates betw...

Romy, I have been trying to explain to myself what happened and how I got to it and trying to recreate this wonderful boiling point.
I tried to make a write up of all the steps needed in order to make it happen, but it is ever so elusive. I ...

Yes, I do feel that letting a diaphragm to idle less (means
more loading) you can tame the code resonance, and the ringgy metal cone in particular
but it might be done in context of worsening upper transients and over-damping
the lower driver knee...

Listening my Macondo with new “Fundamental channel” I noted that my tweeter is not as effective as it use to be. The effect of “not-effectiveness” is very minor but at some recordings it is notable. My T350 still sorts the Vitavox S2’s top but it als...
