July 25th, 1952
The original K-5-H high frequency horn of the patent was modified to become the K-5-J. This involved changing the vertical taper so that the dividers ("boats") could be removed. This resulted in a production cost savings, not an acoustical improvement.
K-5-J was used until 1964
High sensitivity, wide dynamic range, low distortion, and smooth frequency response. Pwk
