[quote user="oxric"] If the issue is merely to recreate a better sense of the live performance….[/quote]It might be not “recreate a better sense of the live performance” but rather to be able to administer in my own and deliberate way some “listening...

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 ...

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:

[quote user="Romy the Cat"]I have to admit that I have written a few pieces of writing about my experiences with YO186 but I withhold to post it as I do not know if it might valuable for anybody. It looks like no one use YO186 on West. There are ...

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...

Just how important are subharmonics and undertones in audio, and how they affect tone? I played around for a while with the Townshend supertweeters, this is a ribbon tweeter that you can barely listen to: you plug it in and put it next to your...

Tuga,
I do not think we spoke about the specific problem of the single-driver class and one of the reason why I never brought it up was because I presume that every person with sane knows them and those problems are not even arguable.
However I wou...

[quote user="Telus"]Has this situation changed at all? Has it been remedied? Did you ever get to the bottom of it?[/quote]Nope, unfortunately it did not. It kind of creating problems not as I am about to plug in the new “fundament...
|
[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,...
|
[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...
|
[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...

Jacky, so, you are the person who did that presentation at
the video was posted by xandcg a few days back and who presumably found the company,
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...

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)...

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...

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. ...
|
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 ...

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...

[quote user="Murataltuev"] What Macondo
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...

[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...

Martinshorn , that for feedback, as I always preach:
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...

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...
|
[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...
|
[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...
|
[quote user="jessie.dazzle"]So if I understand correctly, you are still using both elements of the Red, but have separated them, and now have the HF element as shown in the above photo, and the woofer is still in the large box (still sitting up on to...
