H3 is definitely not discontinued. TIP: The H3 consists of a 15" horn with the rear chamber ported next to the 1", while the 10" driver is loaded in a 70x40 horn with a phase ball in it (phase plug, but more like a small ball with one end shaped to be parallel to the dust cap of the driver. if you search, you can find pics of the inside of one on this forum.
