I was listening light night the Charles Ives’ Fourth Symphony by the kids of American Symphony Orchestra and Members of Schola Cantorum under the baton of probably 180 years old Leopold Stokowski. Ives music is not exactly my cap of tea but I hardly ...

I got it!
I realty have got it this time and it is exactly what I was craving for and shooting for. I converted both channels for 18db/octave on tweeter and recalibrated the whole Macondo, in a slightly different manner...

[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...

I tend to think that we are not copying Romy, but more that he has generated a school of thought on audio and yes horns speakers also.I too have a system following some of the Macondo Axioms, but have used all diferent drivers.As with other drivers, ...

[quote user="Romy the Cat"]My few period DHT tube all have this springy sound but they also has a long decay of rattling. It is like string attached under the bottom of the drum and when the drum sound dies away them strings continues to vibrate. I ...

I was right before but now I really review my rightness for a new perspective. Yes, the compressions drivers are the subject of clean signal but it what I witness with the new 6-chenals DSET put what I said above in another extreme dimension. I do no...

Thanks, el`Ol
What I wonderful devise to position a tweeter on it! It has even perfect size for my Water Drop! It will not help in my case as my tweeter is firmly makes and my MF channel is flimsy but for somebody why would need a perfect tweeter al...

[quote user="Lbjefferies7"] Very good. Raal 70-20XR...interesting. [/quote]
Oh, yes, the 70-20XR is very interesting. I did not have this driver but Alex allowed me to experimented with some elements of it’s design in context on my “Wa...

[quote user="Paul S"]Romy, when you mention "dynamic sinking" of ribbons are you speaking of sub-8k Hz use of powerful ribbons like the Water Drop compared to 109 dB efficient compression drivers, or do you notice this dynamic sinking no matter ...

[quote user="Paul S"]...Among after-market things for the Versa was a system of tanks, hoses and filters designed to deal with the moisture and variable pressure that beset the original system, and there were also various after market pumps, and blim...

Being old and long active in hi-fi, I have cleaned a Lot of records over Many years. Further, I bought a Nitty Gritty 2.5 FI scrubber/vacuum machine back in 1988, so plenty of experience effing around with that, too. And I've tried at least a dozen...

[quote user="Romy the Cat"][quote user="drdna"]As I had been looking at all these tubes I began to also inspect their interior construction. This will amuse you: one thing I would do is to hold the tube right up to my ear so the glass would be touchi...

BTW, I would like to mention one more opportunity for the folks who are playing with S2 driver.
There is another interesting tweeter option: use the HF section of the Tannoy’s dual concentric drivers (only form 50s-60s). The design of those drivers ...

OK, I’ve been for a while but I think I am ready to move forward. Sine the project with Water Drop Tweeter is over successfully and I know the final detentions of the tweeter and its radiation parent that will be used in Macondo I might finales every...

Well it is quite amassing discovers not the fact itself, it is well known, but the amplitude with which the fact demonstrates itself.
I run the “Water Drop” at 12K second order but not against the tweeter transformer but against an 8R voltage divide...

Well, never say never and what I said that the Injection Channel is done it meant that it WAS done. I am experimenting now with other way of use Red injection. The application as is at the picture practically had no impact to imaging. However, I need...

[quote user="Jorge"]About the looks, well I listen to music with my eyes closed, so I dont really care.[/quote] Well, it is not how I see it. The topology of acoustic systems like Macondo implies the stand-alone tweeters. So, why do not make it attra...

Of cause your reply does not cover the subject that I was asking, which is fine, I do not mind. The subtle point that I constantly was trying to make (and that looks like escapes from understanding of the people who are afraid to use the term Lecleac...

[quote user="Romy the Cat"] In the 2008 I have a few immediate goals:
1) Finalize the 6-chennals version of Super Melquiades and integrate it with Macondo
2) Finalize the “End of Life" Phonostage:
3) ...

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...

Thanks, Paul
I have seen your comment about the TAD bug screens at AA. The bug screens are a touchy subject – with some driver removing them works fine with some made sound worse. I did not experiment with TAD’s bug screens…
Generally the bug scree...

As some you guys who flow this thread know my search for Macondo lead me to the world of ribbons. In the mid of last October some of you (I believe it was Chris) pointed out to the RAAL company. I was skeptical but decided to explore the opportunely....

[quote user="Paul S"]Based on previous trials, I have avoided putting resistors on my new ribbons so far. Finding decent caps and coils has been enough of a problem already, since everything comes through so clearly. Maybe a variable indu...

[quote user="Romy the Cat"]The contemporary productions DHT tubes (Russian of Chinese) are superbly firm and have no internal noise when they shacked or hit. The mintage 60 years old tubes what you make the “close to ears” test responses like as some...

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 top?), and filtered to simulat...

Ok, it turned out that I had all caps and coils "in stock" necessary to adjust the filters very close to Romy's recommendations.Its still not perfect, and I had the mic 1m from the membrane of the driver (had not yet rea...

Well, this for the tip of multi-layering the vertical panel. I like it a lot. I will allow keeping the mild panel thinner and more “airy” visually. The total high of the thing will be not 8’ for rather somewhere slightly above 6’. Also, I review the ...

Actually it is good that you reminded me about the Tannoys as behind my recent paranoia with the “Water Drop” tweeter I forgot about the beauty that blessed my life. I am taking about the “older” Tannoy’s tweeters. What is magnificent sound!
I’m not...

I was kind of frustrated with some strange high frequency roll off at my HF and Injection channels. It should not happen. The 9H OPT LL1627 in Injection channels should be good up to 23kHz according to my former tests with a full range Milq and the T...
