It is cost effective (because it is light-weight), but there is a bottleneck (or performance ceiling). If one really want to make cylinder subs, I would recommend drum shelf plywood. They come with various ply numbers and thickness. I would say 3/4" thickness is the minimal. It is definitely heavier and stiffer than sonotubes (which is paper based) that most DIYer are recommended. Due to its supply/manufacturing difficulty, we don't plan to offer any cylinder subwoofer.
