Ok, now it is done and it is official as I see nothing available for conceptual improvement in the crossover circuit. Interestingly this version offers the most interesting sound as well, since the circus was tune for sound, not vise-versa, it is wha...

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 kept vary and kept the fra...

It hard at this point to sat anything defiantly about the Super Melquiades sound. Positively to derive the speakers directly from amp with no speaker-level crossover does provide multiple and multiple benefits. So, Even if to subtract all other “diff...

I was telling somewhere that in case you have built Super
Milq then you need to label everything. My Milq has test point at plates of the
first tube, the bias and plates of second tube. It means 3 test points per channel,
time 6 channels it makes ...

I think I like what it adds to 8-14k range also, so If I use higher order may be I'll miss it...but I'll try if you suggest.I would like to ask a question regarding 400-1200 range (fundamental channel). You are using Vitavox S2 for this range. Is it ...

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. EV T25 2" phenolic com...

Very interesting. I appreciate that you have exposed more of your listening sensations - that give more objective information, letting to propose more accurately what might took place. In regard to what you say it might not be the “phase ...

[quote user="drdna"] This is why the discussion of the Injection channel and the use of the loudspeaker like a resonant musical instrument is so apt. [/quote] Indeed, I did not realized that I shifted my thinking in this thread and an in my general v...

Whoever implemented and experimented with my slicing of lower MF range by 3 channels (Upperbass, Fundamentals, and MF) know how powerful it might be. Changing loading and volume of each of the channels it is possible to write any sound one might ...

As I said above - the myth of my easy replaceable tubes for my MF channel got evaporated. Sure, it is physically possible to plug in those 2A3, 45 or 4V tube and they all will work fine but Macondo will not tolerate it. In fact getting now the p...

Is that the same as the melody range? Defined per this discussion:http://www.goodsoundclub.com/Forums/ShowPost.aspx?postID=1421#1421Where is the fundamental range in relation to the melody range? Low C is 128 Hz. and it seems to me low C is in the me...

Ok, now it looks like the amp is operational. I was listing today the individual channels (without tweeter – the 175:1 transformer is coming). The channels do sound very promising… here are some sweeps with the filter on. All channels use well warns ...

I set two multicells with LF-enabled S3 drivers. I set them on the outer side of Macondo MF. Playing with crossover, volume and towing of the multicells I was able to a degree to get the effect that would like to get. The pointing the multicell...

"...What I expected the S3 does very well – it runs at 600Hz with first order with no “issue” in the bottom region (250Hz Tratrix horn). The next step will be lowering the crossover point to 500-550Hz (that are ultimate objectives)... ...

After spending two weeks with high-passed Celestion SL-600 reinforced with external LF section I would like to make some observations. I had a single SL-600 monitor (I always tend to use one for assessment purpose) on it’s original stands in the very...

[quote user="Jorge"] I dont expect any big changes on my system with them, but i want to be surprised![/quote] If you have a good 10’ driver then going with the same horn to 4” and 8” Fane will give you some advantage. You will pick up some EQ at low...

[quote user="Jorge"] I will take very careful measurements and notes of the set up in order to be able to keep it sounding, try to get the other channel to do it, and hopefully someday reproduce it again if it is lost! [/quote] Jorge. I absolutely...

I found an interesting flow in the sound of my current OPTS and while it will be certified I am experimenting with park of amorphous core transformers that left over from my former projects. I am trying to remap my Tribute but it is just 40mA. It...

[quote user="be"] Instead of defining the ULF range from the reproduced instruments, it is much smarter to do it based on the first resonance frequency of the listening room, because the frequency response of a closed room has a 12dB/oct rise in ...

As I wrote before I picked some Vitavox S3 driver.

and I was expediting with them recently to use in Fundamental Chanel. My idea was that S3 might care LF knee better then S2. In past I had S3 ...

Last week and this weekend I been spending some considerable amount of time and efforts to do what I intended to do for long time – to finalize the Macondo’s ideas. What I mean is that with all Melquiades progress, the fundamental channel, with Injec...
