As discussed in the goals section of this article, I was attempting to create a speaker with a somewhat unique look and design, but that kept to a more-or-less standard layout and driver configuration. I spent a lot of time drawing various enclosure shapes and designs, evaluating them for uniqueness and practicality. I didn't want to design something that was near-impossible to fabricate, nor that required overly expensive materials or tools.
The design I settled on I call "Cantilevered Cylinder with Scoop." The foundation of this design is a basic cylinder, with a "slice" taken out of it. The football-shaped baffle creates an interesting set of curves and lines, while the rearward slant adds a graceful touch and prevents the speakers from being too industrial looking. Metal legs serve a dual purpose of supporting the cantilever and allowing clearance for a downward-firing port.
The final dimensions of the speaker cylinder itself are 8-3/4" diameter by 56" in length. A 10 degree rearward sweep plus 2" tall legs yields a final height of 57". The gross internal volume of the cabinet without the scoop, port, or internal bracing is approximately 1.6 cu. ft. With the 3" x 8" down-firing port, the net usable volume seen by the drivers is roughly 1.1 cu. ft.
