The Gimbal Horns are so named because they are adjustable on two axes. They are ceiling mounted and this exploits a part of interior architecture that is often overlooked.
These horns are being made in our usual fashion – bending recycled newsprint over a steaming iron using a mandrel. The panels are then glued together and reinforced with dryer lint. Special alignment fixtures assure correct orientation of the mounting flanges. The cylindrical compression chambers are laminated together using birch wood wrapped inside a jig using an inflatable ball as a clamp. This forms an extremely rigid platform for the driver and horn.
Here is a slideshow of photos taken during the building process. More info and photos about this project can be found in my other Blog posts:
