Maybe same as I found before. But you don't need to unzip a pdf.

They were very common in Italy in the 80s, me and my brother built two units at that time, that we still have, (look at my avatar), we had the drawings from the official JBL distributor and use two 2240H, for home use or small clubs with two of them you have enough beer! Of course they don't go low down to 20 HZ, but they rock and move a lot of air, I remember at that time sometimes we play some Telarc CDs whith organ, you can feel the air coming from the reflex port at a couple of meters distance. If you stack more units they go lower, read at the instructions in the project, in my opinion a nice horn project.
