Need help to identify a bi-radial horn

[UreiCollector]

Everyone,

I have a set of bi-radial horns (cheek type, not flat front), with 2417H compression drivers mounted to the back. The front of the horn measures 8.75in x 9in, and the throat is threaded 1in.

I'm not sure what the model # is of this horn, and what the freq response will be. I'm especially interested in the low freq cutoff of the horn. If anyone can provide the spec sheet for this horn, I would be greatly appreciative! I've tried google searches, but came up empty handed.

Thanks in advance! :)

It sounds like a 2342, though I couldn't find specific info on exact specs. Here's some, though: http://www.jblproservice.com/pdf/Theatre%20Series/3678HF.pdf

If you go into the 4425 brochure you can use the directivity and FR plots to get a good look at the horns performance.
