Box for bass guitar speakers (Jerihon tube :)

grabcad

In 1974 For the musicians in my unit of Soviet army, I made a special box for the bass guitar speaker system.We used 2 “25A-13” loudspeakers from the “Ukraine-4” movie projector kit with a diameter of 12 inches.That was the idea of my friend musician. It seemed to us that the sound was better, but maybe it was just an illusion.I used the materials that were available: 16 mm chipboard and 3 mm plywood. The shape of the bell is completely arbitrary (by the size of the materials).
