These items came from a large collection the owner acquired over the years.


JBL suggested their slant-plate

lens from the JBL 2395 (Item 0211) for use with

this horn. Horn length 23.5"; mouth 16x9"

exponential flare constant 0.165 inch^


CONDITION: Has area in need of repair as shown

in picture. Horn material is cellulose fiber and

glue. End flanges are wood.


This horn was designed and built in 1974, in consultation with JBL’s chief engineer. It is a larger and lower-frequency version of JBL’s H5039/2309 rectangular horn, for use with the JBL 375 driver. The 375 driver is capable of handling 60 watts of continuous power down to 300 Hz if properly loaded.


While this horn (when repaired) is functional, it was constructed as an experiment, and for possible use as a pattern for sand-casting additional aluminum horns. In the event it is used as a pattern, one might want to increase the thickness of the horn walls by adding additional material to the outer surface of the horn. This, of course, would leave the shape of the inner surface unchanged.

The experimental horn materials are wood, fiber and glue. 


This horn is suitable as a mold pattern for making another one.
