I would like to point out that copying or not copying Macondo is kind of irrelevant. With proper assessment techniques any person who experiment with horn-loaded multi-channel pile of the horns would end up with the very same configuration – nothing else works.  I discovered and formulated Macondo topology but claim any invention of it would be stupid. The whole idea behind the Macondo after I discovered that does work was to share it and to advance the horn thinking out there. I know I did it.

It you would like to learn more about Macondo then you might read the Macondo page.

… that gives the historic parley into how it was. The core of Macondo destine is 4” throat on upperbass driver. I know that it sounds contra-intuitive but everything in Macondo derives from it. If I know nothing about Macondo and if you ask me to draw the most likely design for multi-channel pile of the horns where 4” upperbass is used then I would end up with identical to Macondo design. Charlus looks like have his hard set on Vitavox AK151 for Upper bass – this is very different driver and it will not work in Macondo- like topology. I personally feel that AK151 is more interesting driver for upperbass religion than hat I use in Macondo but I do challenge  Charlus or anybody to come up with interesting upperbass channels that would host this driver. You see to make upperbass channel is very intricate as it is not only about sound but about make other categories.  I would love to use this driver for upperbass but I do not know how if you do them God bless you. The way how Vox Olympian use it might produce good sound but I do not like esthetics – I wanted the pile of identical radial horns of different size. – I do not want to have boxes mixed with horns.   You might feel different but it will be your speaker not mind.

You would not need any tools beside of very basic and very simple RTA, feel free to buy whatever else you wish but it would be unnecessary.

Yes, for sure the building the horns themselves you need to outsource.  It might be Jeffrey Jackson (very good souse) or some if yours more local guys but keep your design decisions belong yourself. Your horns makers shell not drive your specification – you have to do it. If the horn builder do not want to work under control of your requirements and insist to design for you’re an entire system then fire the horn builder. You will be surprised to learn that the more experienced in general audio the horn builders are the more accommodating they will be. BTW, posting here Jorge has in his disposal a horn-building shop and I know that he had built some custom horns. You might chat with his about what he might offer.

I think that if you willing to dive into this project then you need to find out what upperbass you will be pursuing. This is very fundamentally-important as everything else will be deriving from it. If you like the Vox Olympian upperbass then it might be very possible to meet with gentleman who is behind the Olympian to purposefully listening just the Olympian upperbass. With and without other channels and conclude for yourself that it is what you want.  I do not know the guy but generally I know that if you will be able to shape your inquiry in dignified and intelligent format then no one will refuse to help you.  I am sure that if you sight some kind non-compete agreement and buy to the guy as box of Dom Pérignon then he would help you. Do not treat anybody experience as some kind of fixed entity – you very much might improve upon what Olympian upperbass does….
