Dayton Audio RS621 Speaker Kit w/o Cabinet
Can someone give me advice on a cylindrical cabinet dimension?
I'm a product designer, and I'm just getting into speaker building (mostly as a hobby). My goal is to create a set of speaker boxes, using this kit, that are half-cylinders (when not in use the speaker faces could potentially face each other creating a full cylinder). If the inside diameter of the enclosure is 8", how deep do I need to go? I may house the crossovers in a compartment below the top enclosure. Any advice or alarms with the shape would be helpful.
Design and engineering are strange bedfellows... Start with your vision, but engineer backwards. You have to have a flat baffle for the drivers to mount to. Behind that, you need to have the correct cubic volume, in this case, .25 cu ft. Using pi-r-squared, you can determine the size of the cabinet using a curved surface. Generally speaking, this project won't easily lend itself to the shape. Larger cabinets would. There was a speaker in the 80's that used a cardboard tube with a section cut out for the front baffle. It was a very good product both visually and inherently acoustically due to the properties of the cabinet and construction. Outside of your design concept - you are just dealing with simple math. Good luck.
