Herman, horn dimensions does not described by size of driver but only size of throat. It will be absolutely nothing changed in the horn dimensions if you go from between 10" and 12" driver. Sure you would need a bit larger back side of the horn to accommodate larger driver and if you use the size of throat you will have more compression with larger driver. To assess how it will affect sound is absolute imposable. Some of the drivers are fine to work in too small throat, some not. Put in the perspective the variable size of back chamber and variable of the lading from amplifier and you have absolutely unpredictable situation when the only empirical tests can indicate something. Frankly I do not take seriously your preference of one driver over another driver. If you heard them “just for fun, without mounting in a box” then what you hears was absolutely irrelevant and their performance in the horn, in the back chamber will be absolutely different.

I am not sure what you are doing and what you are looking. My view is that to find a horn builder is not complicated task. It is much more complicated to figure out what you want and how you want the things done. It is like building a house. It is not complex to cut wood, poor concrete and attach pipes. It is much more complicated to evaluate life style and come up with a design what house shall be and what it have to future. Trust me, if you have a very definitive idea what you want then the builder will run to you, literally. If you have flimsy frustration that you just want something but not quite sure what you want then some experienced boulders would prefer to stay away, unless they are absolutely broke.

I do not insist that it was what happened in your case but what I discovered with my contractors that I hired to work on my house was that the best way to be invisible is do not have firm expectations from this service.
