If you could start from the beginning...
Hi Romy 
you mentioned once somewhere, knowing upfront youd add the resonance channel, you had it all done different.What particularly you would make different in your system?  
cheers, Josh

What if….
Josh, this was an excellent question and I was asking myself the same question a lot during the different stages of my understanding of the Macondo architecture. I would not call it “resonance channel” but rather the “injection channel” as it not actually adds any resonances but we understand what the question implies. So, here is the thoughts that I have. If I design Macondo from scratch and knowing what I know how about employing the injection channel then I would make the following things different:   

1)      I would provide more prominent location for my Injection Channel, in vertically aligned position, probably between tweeter and fundamental channel. Probably I would put it in a tube, trying to keep the face footprint as low as possible.   
 
2)      I would spend less efforts on MF DSET as I feel that a proper selection of Injection Channel, driver might very might override the efforts over DHT of MF channel.   

3)      As I would know the dimension of my Injection Channel enclosure I would put the high pas filter in the Injection Channel amplifier. Even though my Injection Channel drives now my midbass there is no need to have a speak-level filter at midbass. The inner stage cap inside the Milq would do the duty perfectly fine, in addition protecting the Injection Channel OPT from any saturation of overpowering. 
   
Rgs,

In the middle???
Hi Romy  Im just trying to imagine that. If you got to keep the vertical offset small, between the ways, this would rip a hole in the middle, wouldnt it ?  Also bit surprising as i thought you liked the injector on the ground initially. 
I hope I understood correctly from your posts, a horizontal offset is a no go always for all channels? (would be convinient to put the injector on the side) 
Also a distance offset (traveling time from channel to ear, or as some may call it time alignment) is not possible? (would be convinient to put the injector behind the tweeters) 
Then not much left of options, only on the top, which is too high, in the middle it rips the channels apart. 
Last option, ground level, would elevate the fundamental channel to the very top, which is a dramatic loss of 6dB gain not to have the floor as a horn-mirror-boost...Im lost there.  cheers,Josh

I will do it when I have time.
I do not advocate injector on the ground. The way how I use my injector I high pass is aggressively, so the ground coupling is not a requirement. If somebody use injection at lower octaves then it might be a merit to do so but not in context of my injection. 
 
It is absolutely prohibitive in my view to have injection with arrival offset, the time aliment is absolutely mandatory. Now, there is very valid debatable question. If you for instance locate injection channel above the teeter then you have less tight vertical horns island. If you have the injection channel located on the side of the tweeter then you have more compact horns configuration but you introduce a horizontal offset and probably too much reflection from the tweeter.  What approach provides more damage to sound? I would have difficulty to answer this question. I did the vertical alignment and did not experiment with horizontal offset. The vertical alignment, since the injection has high output in top octaves, does damage imaging to a degree. Will this damage be more or less if I use horizontal offset? I do not have the answer. I bought 6 months back of so a coupe, of 10” tubes incisures and as I have time I was planning to put the 10” Tannoy in there and try it horizontally offset injectors. The problem is that I do not have now any good harness to hold it on my frame to assure a stable time positioning and time alignment. I will go for this when I have time.
