Loudspeakers are always a musical instrument but even in musical instruments it is always a question what produces more portion of  sound – the fundamental of a vibrating string or the resonance and after-tones of the instrument’s deck. I wish I have skills to control the natural “Resonating Oops” – I do not have them, nether I have in Macondo tools and means to do so. The Injection, I feel, is a good substitute where the Resonating Oops’ benefits are delivered in a predetermined and well managed format.

I owned a pair of 5’’ semi-omni, open bottom, resonant single drivers for a brief period - they where my main speakers at the time (I wonder how sane I was when I bought them). The resonances were so overpowering that one could hear more of them than the sound produced by the driver. They were improperly designed for main speakers but a similar approach might make a nice pair of resonance and ambiance "injectors"...

The Russian take on the “Resonance Oops”

There is a speaker maker in Russia, Moscow – Alexander Kniysev who just introduced his own take on “Resonance Oops”. What he does is not my cap of tea and I see a number of issues with his design that I would object but it is not my speaker. Nevertheless what Alexander does with this implementation and how he thinks about it I feel is very worthy attention. Watch out the lazy Feastrex people – this is what you should be doing. Here are some free translations of the comments Alexander made in responses to my questions.

“Those panels are rather an outcome of my intuition about sound then a design based upon formal acoustic principles.”

“The system implies harmonic integrations between driver and panel “

“In my view the panel influences sound much more then driver, I generally consider that if an audio acoustic system speaks only via a driver then it is a mistaken acoustic system.”


Certainly Mr. Kniysev’s way to implement the “Resonance Oops” and my ways are very different but it is what it is and I think Alexander’s attempt is educational.  The Alexander speaker has 96dB sensitivity and employs  in-house made dual-concentric alnico driver with both paper cones and leather suspension.

Excess of HF?

 Romy the Cat wrote:

Not will everyone “get” it, or would agree with it but… where did you see me to care….

Q: What is the worst aspect of sound reproduction?

A: Excessive HF response of playback. A flat response above 5-6kHz is indication of dynamic and transient deficiency of playback.

So, what it has to do with Injection Channel?  Well, when I properly setup Macondo Injection then I might slightly roll-off the HF knee of my MF channel for 1.5-2dB (of combined output) and it does have no negative (means positive in my book) impact to listening awareness.

Rgs, Romy the Cat


Romy, I hope you don't mind me taking this outside of thread - or perhaps you would see fit to move (or remove) it? (Maybe you could even move it to the thread where we discussed my recordings - it could be relevant there).

Regarding your position on the 'flatness of reproduction', as described above, do you think that this could be a response to distortion in recordings?

Does your system run such a 'roll-off'? If so, do you have the facility to run the system flat?

I very much understand your point and well-understand what you did not say. I still stick to what I proposed above but there is so much more to it.  I feel that it is incredibly interesting subject and is way beyond current thread. If you wish the might formulate the theme and start another thread.

The location of my Injection Channel.
fiogf49gjkf0d
With the late success in my battle with electricity I was slowly reviewing some of my things. What I detected that in context of good electricity I can set up my Injection Channel much more aggressive, let seat 2-3dB more than I did before (not it is at minus 12dB). However, the location of my Injection Channel begin to be a factor in my room as it begin to offset imaging height more then I would allow it to be. It is sad as I am not willing to do anything with it (even I do have some ideas what might be done). Nevertheless, if some of you are planning to use the Injection Channel then I would encourage you to design the system from scratch where your Injection Channel would be at manageable height.

In the context of this thread: It might be ineteresting (if less glamorous) to apply this technology to a mid-range speaker cabinet designed to resonate.

In the context of humanity: The world could definitely use a lot more guys like Francis Schwarz!

Injection channel location
fiogf49gjkf0d
Romy,

Any thoughts yet as to Injection Channel location/integration in new room? 

Selfish question, I recently got a pair of reds, and have been trying to think of how to place them/type of enclosure to build,
 without disturbing image, or too much diffraction (hidden behind mouth of mid-bass horn).  

And if height offsets image, a time aligned rotation to the sides might be even more noticeable?
(Or not, haven't tried, sometimes things sound different than I expect...)

Robert, it was a  very good timing for this question as it is exactly what I am been thinking/working now. Last night I was up to 5AM, listening, moving the speakers and I think I did found a very good configuration for Macondo in the room. I did not use the Injection Channel and now I think HOW I can use it.  I might use it as I used it before. It works but I would like to see if any more elegant solutions are available. I do NOT intend to use Macondo without Injection Channel but I do admit that that are some disadvantages of that location I have before. Now I have much bigger room and a lot of space from any side of Macondo. I might come up with an interesting new Injection Channel location.

I wonder if the new room, with its high ceiling, added volume and remote-from-the-speakers sidewalls, will accept "off-axis" presentations from the oops channels.

Combined Injection and Bias Channels?
fiogf49gjkf0d
Hm, in an idea come to me today I think I will try very soon. Why do not combine my Injection Channels with Horizontal Bias Channels? Since my Injection Channels have HF transducers then it will introduce a tremendous lobbing BUT… But my Injection Channels run at 12-15 dB lower compare to the main channels and it might juts work. Sure it will introduce SOME negative effects but it will also do an interesting biasing effect not to mention the necessary Red Injection. My new room has a phenomenal space to try this configuration and I will certainly try it, perhaps tonight.
What I after is not the horizontal width of presentation – my playback does it very fine as is but for shaping the curvature and feelings of the peripherals…

A fiasco of the Bias Channel idea.
fiogf49gjkf0d
I did try it and it was very bad. The Bias Channel did not affect imagine but only made soundstage wider, which was not my intention. Along with the widening of soundstage it made a LOT of other very negative impacts, namely increase compression, made imaging very simplistic and a few others. What also remarkable was that the Bias Channel did horizontal biasing much stronger then injection, in fact the tone was divested by biasing so much that the injection was not very sensible. 

 So, looking at all of it I put Injection Channel back what it was – above the Macondo and it did what it had to do. I would say that if to embrace damage from Injection Channel then in the “above: position it has the less amount or it – it was expected and the explanations is self-evident. Considering the encased listening distance I recognize less damage then I had in my old room. I will keep the Injection Channel as it is now –in “above” configuration for now.

Injection Channel is about very high precision.
fiogf49gjkf0d

Yesterday a guy come me from Atlanta to “see” my new installation.  I kind of explained that I am not in “demo mode” now but he still came to “see it”. I have no idea what he wanted to “see” and I was kind of obligated to play something to him. I had only one channel, but still not properly finally tined and not aligned. When I listen it I know what I want to her and I can make mental corrections and extrapolations as I know what is not done yet. He of course is not able to do it, so he has no ability to understand what I was trying to show off with the sound.

Anyhow, the Macondo in my view did not sound properly at all. We were listening just left channel sonly (only one midbass is connected), I played some oldies from 20 and 30s. He looked like he liked it – I have no idea what he was listening... It is not the point. The point is that in the end of the listening he asked about the Injection Channel and I decided to demonstrate it’s effectiveness. So, I did what I usually do – let to listen and then to plug in and out the Injection Channel.  It is interesting that I was forced to crank the Injection Channel up to -4dB in order the Atlanta guy to hear any difference.  What he did not know was that last weekend a friend of my stopped by to help me to put the Injection Channel above the Macondo… in absolutely random position. There was no alignment of Injection Channel’s tweeter to the Macondo’s tweeter done. So, the Injection Channel at -4dB was not as effective as it was in aligned position at -12dB. When the Atlanta left I give some listening and tuning to Injection Channel and I concluded that if the Injection Channel is not properly setup then it MUST NOT BE USED.

So, as ridicules as Injection Channel is , the Injection Channel is VERY powerful tool ONLY if it properly setup and properly used, otherwise it is just a waste. I know that are some folk out there who are trying to implement Injection Channels for themselves, make a mental note for yourself: if there is a super premise time aliment and frequency/amplitude dialing in then the Injection idea will not work.

Injection channel redux
fiogf49gjkf0d

Here's what I've been trying. 8 ohm 4.5 inch full range Omega driver in a 0.35 cu ft sealed box and 6 mH coil 200 Hz electrical crossover. The main speaker is JBL Array 1000. This full range driver has my favorite *tone* of all I have tried. The cone is made of hemp. The juice is grape. So far (3 days) I like the results: More gripping musical presentation and more expressive. The instruments and singers still exist realistically but now within an expanded space. I need more time to evaluate but I think it's working. Makes me want to conduct!

Injection channel shall not affect the “expanded space”. The special impacts that you have are most like from time misalignment between the JBL tweeter and Omega driver. After the alignment add volume control to Omega and try to dial-in it’s output

Further along with injection channel.
fiogf49gjkf0d
Now that I have the Omega injection channel phase aligned I am finding it extremely interesting. I think I want 3 or 4 injection channel drivers/arrangements for the different types of music. The Omega works great for vocal and woodwind (which I listen to a lot) but is less effective for organ or brass and even less so for strings.

Have you a set of injection channel solutions which you can swap in and out as the musical content demands? Maybe a *honk fog* injection channel for the Strauss horns? I am going to try this. I will have to build a versatile frame to hold the differing driver/box arrangements. I think it will be very rewarding. Thanks so much for the idea and your extensive trials and encouragement.

Sexier Injection Channel box?
fiogf49gjkf0d
As I am slowly put Macondo back to the business a question come to my heard: how can I make the Injection Channel sexier visibly? As now Macondo is re-assembled and reinstalled but with no Injection Channel sitting atop. I extend no room for argument about the sonic benefits of my injection but I do ad mint that I like the parlance of Macondo with no Injection Boxes. I wonder if I can make the Injection Boxes smaller and more attractive.  I high pass the Injection over 110Hz, so why do I need such a large box? Can I cut it on half at least? I have the Tanoy ordinal boxes that I accidently did not trash yet, so if I cross at 110Hz then can I use them? They were kind of ugly as well but I might do some nice looking small boxes by taking a sow and cutting my current box off. I might build own small boxes if I can come up with sexy shape for it…

Sexier injection channel?

Romy,
I travelled back from the Czech Republic yesterday and had lunch at the Pilsner Urquell brewery restaurant. A vintage wooden beer, wine or Cognac barrel would be the sexiest cabinet that I could imagine.

Anti-horn shape cabinet?
fiogf49gjkf0d
Thanks, Robin

I do not drink and the wine/beer cultural cult is a bit above me. I still do appreciate however a good moldy and decadent décor of wine cellar but unfortunately it would be very different for the style of the listening room that I am having and envision. A friend of mine (audio guy) did built large woofers in the actual wine barrels but runs a winery, so his listening room in context:

http://www.stoutridge.com

I was thinking to male it sort of anti-horn with cabinet recedes back. I need to come up with some kind of idea how to do it visually pleasing…. or not to do it at all…

How Important Is Present Box to Sound?
fiogf49gjkf0d
Not that it matters, but I can't remember if that speaker was originally ported or really "sealed".  Some of the old drivers were actually put in "tuned boxes", for better or for worse.  I understand that your objectives for this driver afford you a certain amount of "slack", but it's still probably a crap shoot to find out how new dips and peaks, etc. affect the sound.  In any case, the present box works sonically for you now, so another box would be trial and error, cost vs. benefit, all the way.

Best regards,
Paul S

Horns continued
fiogf49gjkf0d
Why not enclose it in a horn shape? After all, it makes sense for the facing surface to be circular rather than square, and a cone will have the best structural properties, as well as having the closest kinship with the rest of the stack.

Holly Cow! Decoud, what a fantastic idea! How didn’t it come to me?! It might be a light decorative horn, aka Altec 7 MF horn, which would not be deep to attenuate any HF but to be visually complementing the rest of Macondo horns. Truly fantastic idea and it even allow unloading a bit the excursion from the Tanoy driver. Now I need to demine such an asymmetrical horn and find somebody who would do it for me. The design mode is on!!! Thank you, decoud, for the tip.

The La Horns of cause out of picture in my case as there are very narrow requirements in my channels that do not fit what La Horns offer, even though I do plan to use the negative opening from 1-3 sides and to have a transition to flat termination at the bottom. If John Michael would do a custom horn by my design then I do not mind to use his resource as wood maker but frankly I think I need to find somebody closer to home as the shipping cost might be prohibitive.

The idea that I have in my head shall comply with the following requirements:
1)      Shallow 7-6” deep horn with 10” throat and ~24” mouth
2)      The mouth located asymmetrically with the bottom of the throat at 2-3” from the bottom of the horn
3)      Sexy shape that would work “interestingly” alone with the rest of Macondo.

I do not it to be rectangular horn and I am looking for different shapes. Oval would be interning but to make asymmetrical oval would be a huge pain in ass. I need to do some circulations and to see if that type of horn would even affect anything.

Here is a very premature idea that I have in my head.
