I think you have found phenomenally good sounding upper bass driver and you are going to build a dedicated quasi-bassreflex channel using it to fill the gap between your line arrays and the upperbass horns...

Interesting idea but I would not do it. I can make a good midbass direct radiator if I have the “phenomenally good sounding upper bass driver” but at this point of my understanding I would consider it as a mistake. I do not look for good upper bass sound - that might be done with direct radiator but I’m looking for a very specific midbass softness. That might be done only with midbass horn, so I will wait unit I will be able to accommodate such a horn. So, the Macondo 7th channel will be not the midbass direct radiator. In fact looking what you gays are guessing is very interesting for me to analyze but you all guys look at is very different direction from where I am aiming my Macondo 7th channel. I just pledge that the Macondo 7th channel (if it work) will be more interesting the what was proposed an all posts above.

From today’s email:

Question: “…. As my audio system has improved over the years I have found myself continually wanting for something that I could not place my finger on. I suspect that really good sound sytems do too much for our brains and the interaction is stolen away…. Is it possible you have transcended hi-fi? What would be next... “

Answer: Actually, I am working on something in the direction of “transcended hi-fi “. If it goes successfully then I will be talking about it at my site.

To my surprise I got a lot of inquiries about the future Macondo’s 7th channel. I say surprise because I do not particularly feel that people truly understand what Macondo is all about. I have written a page dedicated to Macondo

http://www.romythecat.com/MacondoAcousticSystem.aspx

but there are a few things that prevent people to understand the Macondo Realty. People are no accustomed that what is said in audio has any meaning and they are bombarded by meaningless nouns and adjectives for years and the meaning of the words is diluted.

Anyhow, I have seen the “criticism” of Macondo’s by various people. The irony is that they do not truly underrate what they criticize. They criticize own experience of being unable to get acceptable result for the systems they put together and then they apply the pattern of their failure to Macondo. The personal limitation and the lack of understanding the distinctions between the pile of hours that they put together and a fine-tuned Macondo prevent them to discriminate the differences.

Anyhow, I was receiving emails accusing me that I went too far with Macondo’s 6th channel (the Injection Channel).  One guy was coming to Bosons who proclaimed himself a “speaker guy” and he felt that he appreciated what he read at my site. I met him and to my surprise criticizing Macondo he did not understood what the Macondo’s 6th channel was used for.  Interning that he was a semi- professional speaker designer (on objectivistic side) and he was trying to convince me that the Injection Channel is a mistake. We were sitting in a bar 500 feet from my listening room and I really did not feel to play to him Macondo. Usually 2 minutes of play the Injected Macondo set all doubts and concerns off but it is not the key. I have no need to prove that I am right or wrong – I know myself where I am where. What struck me is disability of this guy (and many others) to understand the objectives that I have with my Macondo and recognize why I do what I do. it was imposable to talk with him about the amplitude of colors and saturation of tones – he was just below those categories. So, I end up do not bring him in my listening room – I saw no personal interest or challenge to prove him anything, not to mention that I do not have interest in his musical preference.

This all bring me to think about the informing the people about the upcoming Macondo’s 7th channel. The Macondo’s Injection Channel deal in specific way with slightly more sophisticated for an ordinary audio person subject of color amplitude but still this subject might have a basic comprehension, particularly if to educate a person and to show “hoe it might be done”.  The Macondo’s 7th channel will deal with much-much more sophisticated layer of listing experiences, something that is very much not dealt in audio before, at least acknowledgeably.  I intentionally do not give up the function name (like Injection, Fundamentals, Upperbass… etc) of the 7th channel (even I do have a very well-define name for it) as I feel it would not be understood.  In fact, among all audio people that I know I might found perhaps 2-3 individuals to whom I might explain what conceptually I am trying to accomplish with the 7th channel and who would be able to understand what am trying to get myself with the 7th channel . I can only say that it is VERY much different (purpose-vise) from whatever was proposed, and from whatever exists out there.

It is all that I am willing to say at this point.

Romy, perhaps you can give your 7th a photographic based analogy which you seek improvement on. Just don't say photo stitching ... Wavelength dependent level /hue /sat adjustment ? (gamma + black and white point) This will be recording specific though...

Very interesting question, Collin!

I tried to think how would I answer it and I was not able found an analogy in the existing photography, and I know photography quite well. Let my give a far-stretched association from my past and perhaps to offer a tip for your guessing.

25 or so years ago I was trying to present one of my works at a meeting of a local photographic club. It was a portrait of a girl, made in very dark keys with slightly bleached (it was at the time of silver photography) eye’s sclera (the white part of eye). The portrait was OK but it did not work from my perspective at regular ambient light. So, I deseeded to present the work in the room with lights off and light the image up with a single candle, located at very sharp angle from the print…. So, now let go from that invent into the realm of fantasies…

Pretend that the candle glows in room with deficient amount of oxygen and ready to extinct. You are watching at the portrait and have you have a reaction sensor attached to you perception. The sensor outputs a feed to a mechanism that generates oxygen. So, watching the image and experiencing sensations you by your reaction my consciously or subconsciously affect the saturation of oxygen in the room and consequentially the forces with which the image might be lighted.  Now, pretend that you aware about the oxygen status in the room and you might mimic your reaction (just for sake of oxygen) before the image ever is shown to you. You might send with your sensory feedback some sort of instructions to the oxygen generator, picking the best light conditions for given coming images. At this point you need to include into to the “ceremony” the fact that you need oxygen to breath and the fact that if you put too much oxygen in the room then you will end up with the fate of “Apollo 1”.

Now, pretend that the image-impact-sensations-oxygenization-light-image is not straight one-dimensional pipeline but the “ritual” has 10-20 dimensions in fact n-number of dimensions that all work simultaneously and instantaneously.  Well, if you still read it then you are getting the idea what I a trying to imply…

Romy, that’s a very interesting concept that could dramatically alter the perception indeed.

You mention it as the 7th channel as a means but this must have steering/contouring from an “intelligent” source.

Do you have to wear a helmet for this or does it track hand movements.. J

Ahhhh now I get it, you want to be the conductor !

This must surely be done in the digital domain as well then.. many things are possible here !

Will this push the 7th or the first 6 as well?

Nope, it will be done at electro-magneto-acoustical domain. No helmet will be involved ether. The Cat

Just thinking and writing out loud, and I'm probably way off track :

Sort of analogous to the effect of introducing, at strategic intervals, varying doses of nitrous-oxide to the cycle of an internal combustion motor, in which case the motor developes a kind of wonderful supernatural power; or to the expansive performance and self perception displayed and experienced by human beings having had amphetamines introduced into the blood stream.

In an audio system, the resulting output/s might be oriented upwards or away from the listener. Lower MF would be my guess as to the most effective range.

Interesting, to say the least.

Another analogy : The effects generators placed under the seats of the most evolved video games, which transmit via the tactile domain.

Reading my old post about my new R&E adventures

Midbass Horns and Real Estate

http://www.romythecat.com/LatestPosts.aspx?ThreadID=11190

 ….and contemplating on my prospective move to a big room I am strategizing what changes with Macondo and Melquiades it might trigger.

 I will increase the distance from Macondo to listening zone but I still will be in relative nearfiled. I think Macondo/Melquiades will handle the larger space to a degree. I think the limit will be in MF channel. Not I have -3.5dB with YO186 tube or -1dB with type 45. Sticking to YO186/RN460/2A3 I will have extra 3dB that would give me an extra twice distance. So, I might end up driving MF with no attenuation of any kind – VERY cool idea as it will be no inductance fight in secondary. In fact I very much see myself to set up the Macondo distance ….wherever the MF will hit my reference calibration dB pressure. It will be very good idea but it would be in very direct violation of DPoLS. I will see how it works…

The HF channel I have now at -5dB and I think I will be able to go away with it. The same goes with Fundamentals channel – I have a lot of attenuation in there that I might release. The Upperbass channel I hope that will not have problems as I have some of reserve in there. If you look at the Melquiades DSET circuit then in the B channel you can see 30K to 12.1K voltage divider that likes approximately 3dB.

http://www.romythecat.com/Site_Images/6-Chennal_Melquiades_DSET_Amplifier_Rev3.jpg

In addition I might engage the second half of the 3C33C that drives a little bit more gain and power (not a lot thought). Since I will be losing upperbass in the bigger room much faster I think that 3-4 dB that I will pick up by bypassing the Milq divider and use a full 3C33C might be no enough.  So, I am thinking to use the secret weapon of my Macondo – the highpass filter if my Injection channel.  Currently it is 120Hz but I might drive it lower. Combining with upperbass horn it doe VERY good sound and I hope this will allow me to load the bigger room properly.

The pride of my - the Melquiades’ LF channel will be gone in its current format. The monster 7Hz at full power, inductance only OPT transformer probably will be replaced with fast-core inductance only 20Hz transformer and my currant LF channel will be driving my new Midbass horns. The 15-18W of the full 6C33C will be enough I hope.

The biggest change I think will be with Bass channel. There is nothing in my currant setup that will be able to handle sub 40Hz at let say 800 sq feet. I would need to decide on topology of the channel and the amplification. I very much like how my line-array works – in fact I adore them. In the bigger room I would need probably to as 2-4-6 more sections – it will be all depends from the room.  Alternately I might put my array collection of 4 18” Aura drivers in use. Putting them into 40-50 cub feet box each might be a good direction to go. Then how to drive the thing? For 800 sq feet room I would need 200-330W minimum, how to get into this power?  A SS amp is a straightforward chose and it is what I might use initially but I have spoiled with SET bass channels and I would be very cool to have a powerful SET amp.

I might re-read my old threads:

More power from Melquiades? More powerful tube?: http://www.romythecat.com/Forums/ShowPost.aspx?PostID=5200

or

How to get a LOT of SET power: http://www.romythecat.com/Forums/ShowPost.aspx?postID=2136#2136

…  and might try the amp on GU-48 or the similar.

Whatever it is it sounds like it will be a lot of work…
