: : (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

It sounds like a good quality 90 degree constant directivity is the way to go. thanks again.
