The Leaf Spring Mount (LSM), or X-mount, is a longer existing type of shock mount originally developed for the British Navy. It was primarily designed to protect ship borne equipment from underwater explosions, but has found a large number of applications in both military and civil use. The leaf spring mount is currently being replaced more and more by newly developed shock mounts, but is for some applications still the most (cost-)effective solution.
The basic design of a leaf spring mount uses two or more high-tensile stainless steel U-formed leaves, that together form an elliptical shape when joined together in the center with plates. The spaces between the U-formed leaves are filled with a special epoxy resin compound with an extremely low static stiffness
The characteristics of the mount under shock load are determined by the chosen metal construction, while the efficiency of the damping is obtained by the epoxy resin. To improve sound isolation, MSS Defence offers a special version of the LSM with rubber inserts instead of nylon
