: (for club design)
: 1. radial vs. constant directivity?
CD horns attempt to spread the highs evenly
Radial refers to a horn that has the rounded front and tend to be 'more' brighter on axis than off axis than cd horns.
Either can be good, I find that horns that have a smooth, constant and even expansion fom throat to exit sound best.
: 2. 60 degree vs. 90 degree?
Depends on the space to cove. Most likely your decision would be:
"use 3 wide of 60 degree or 2 wide of 90 degree"
Three 60's will give you more SPL but also more interference as well. It is a volume/coverage/cost issue.
: 3. large or small?
Large is usually louder in horn world. Multiple smaller horns may give you wider or more coverage but costs more in drivers etc..
Focusing on good sounding horns and then determine qty based on 60s, 90s or a combination to cover the area.
: i'm trying to figure out the best way to go here, any suggestions would be appreciated. thanks.
Long narrow rooms seem to prefer 60 degree horns, short wide rooms prefer 90s.
Well designed large horns tend to offer better pattern control but also tend to have a range of optimum frequency efficiency. This is the "honky" sound you get from them.
Short wide moth horns tend to have less pattern control, are less efficient but tend to sound smoother.
Hope that helps
