Wayne, The 2344 horn is the one used by JBL in their 4430/4435 studio monitors.
It is the infamous "Butt-cheeks" horn. Very interesting, I had a pair of 4430 monitors and sold them, but just found a pair of 2344 horns and will look a creating a 4430 clone.
They have great dispersion, but don't sound like most other horns.
Just to offer some horn info here!
Regards, Ron
