Post Subject: What I need is a horn architectPosted by noviygera on: 10/25/2011

I understand that "nothing changed in the horn dimensions if you go from between 10" and 12" driver". You are referring to the horn mouth I assume. Do you have a idea what compression ratio is good to have for upper base horn? It seems that 2:1 is talked about for the tractrix by few people here.
So far I have this information:

120Hz horn mouth -- but is that in quarter space or full space?
Tractrix flare
10" or 12" paper driver

There are a few drivers that 10" or 12" paper cone, have very high eff, and also high Fs. Precision Devices, 18 Sound, Beyma, Ciare, Faital, B&C.

Romy, how did you choose your 8" driver from so many other drivers out there? Did you decide on the size first, and then narrowed down your search and then built the horn for that specific driver or the other way around?
I do need to start somewhere.
