  Which of Crowe's horns do you have? This one?
  https://josephcrowe.com/blogs/news/es-450-biradial-no-2143
  
  And might you be using it with any of those drivers?
  
  Or this horn?
  https://josephcrowe.com/products/3d-cad-plans-for-es-290-biradial-horn-horn-no-1670
  
  Again, which drivers?
  
  Also, depending on placement and your room acoustics, do either of those horns, perhaps due to its directivity index, exhibit more of a You are There or a They are Here presentation?
  
  I much appreciate those wise words of caution but this is how I plan to proceed:
  
  I've narrowed my choice of horns to three. Two are either of the above from Crowe. The other would be this new version of the TH4001 horn from Nicolas Badey https://audiohorn.net/next-gen-bi-radial-horn/ While his English is not always especially intelligible, if you click on the Audio Sciences tab at his website you can see that Badey is at least Crowe's equal with horn design. Indeed, I am scouring those pages for at long last I may be finally getting an excellent primer in both the goals of horn design and about room acoustics-and without the heavy math! Crowe offers no such assisted learning at his website, and when I asked him for usable learning materials for dummies he referred me only to a well known but math heavy text on acoustics.
  
  When I invited him to this thread, https://www.diyaudio.com/community/threads/looking-at-yuichi-a-290-or-tad-th-4001-clones-makers.375215/page-15 Badey clearly holds his own when grilled by Docali, who also designed a much more similar looking but apparently quite different version of the 4001 horn. https://sphericalhorns.net/category/radial-horns/
  
  As his last post there, Badey says one of his customers (e.g. X-41 horn https://audiohorn.net/x-shape-horn/ ) from NYC will soon be auditioning the new biradial horn at Badey's home. Presumably, if he loves what he hears the customer will order a pair and install them in his system. Badey then will ask the customer to invite me to hear them with my recordings (uncompressed WAV files of CD track rips). I'm ~ an hour away by train and uber.
  
  And a week or so after the national elections are over, Crowe will arrange to have the owner of this system invite me to hear it. https://josephcrowe.com/products/speaker-system-no-2095 That's a 3.5 hour train trip and an uber to a Washington DC suburb. Note, if I did go
  with either of Crowe's ES horns, instead of those bass horns, Crowe would be using my Altec 416 woofers below one of those ES model horns.
  https://josephcrowe.com/blogs/news/altec-416-8b-in-100l-sealed
  
  OTOH, if I love what I hear from Badey's new biradial horn better than Crowe's, though I haven't asked him yet, I know someone who I'm pretty sure would agree to collect my Altec 416s from Crowe and build that system for me. He's two hour away by car. If not then perhaps that customer
  in NYC might build them.
  
  But NO way would I agree to buy any horn without hearing it in a complete and very good system.
  
  For now a question about drivers: Would these work equally well with my Altec 416 woofers
  https://josephcrowe.com/blogs/news/altec-416-8b-in-100l-sealed and any one of these three horns, with the proper throat adapter?
  
  https://www.usspeaker.com/radian%20745neoBepb-1.htm
  https://usspeaker.com/jbl%202450H-1.htm
  
  Or how much better might the JBL driver work because its bigger 2" diaphragm may allow it to cross lower and closer to the Altec 416's best crossover point, and/or for other reasons?

    Hi
    below message, in these uber senstive times may be out of place. but here goes.
    
    i think you are trying to go diy even though you have no diy-desire, no diy-aptitude, no dyi-skills. furthermore, based on your comments about joe's systems, i dont think you understood the 'pieces' of a horn system.... so you are not really in a position to put a system together on your own. do you really want a high-price system that is unlistenable and un-sellable? also, depending on reviews or other people ears probably wont work --- only you know your own biases and tastes.
    
    i suggest you buy a complete turnkey solution from any of the builders you mention. but remember their rooms are going to be different from your--- so, again, good luck. actually - from a re-sale point of view -- i suggest you stick to 'more' commercial brands --like -- off the top of my head --- jbl, klipsch, car, volti. not sure why you are ignoring these. jbl has (or had) as an m2 setup in manhattan. check it out.
    
    sorry that i could not answer any of your questions the way you wanted.
    
    by the way, i like your enthusiasm. hope you find something that works.
    
    kind regards
    m
