Quoting Didier B
I like it Jeremy even if I don't really like the use of the elastic. No very esthetics in my opinion.
Thanks, Didier! Tried several different liftarm-based latches, but due to the curvature of the speaker face and the trapezoid-like cross-section of the cabinet, none of them held the speaker in securely enough when inverted. They were also clumsy to use and way too conspicuous. The elastic turned out to be best overall solution by far. In the useful gizmo genre, it's function over form, you know.

Nice! I love the use of the tie for rubber feet! I bet they work well!
Thanks, Zachary! These rather hard rubber wheels work well for this MOC, but there's another of similar size but with a slightly softer compound that's even better at keeping things from sliding around.
