MODEL 15

MODEL 15

The SME MODEL 15 is modeled after
the Model 10 (shape, compact design). A slightly modified suspension system from the “Model 20” has been adopted. A distinctive feature of this design is the damping of vibrations in the pickup system, achieved through a system of springs and dampers. As is well known, the stiffer and heavier a given structure is, the less susceptible it is to vibrations. The turntable weighs over 18 kg, which, combined with its compact design, further stiffens the entire structure. The use of appropriate damping optimizes resonance in the higher frequencies. The method of suspending the subchassis on soft rubber dampers is of great importance to the sound, as it does not cause the coloration often found in designs supported by metal springs. MODEL 15 is equipped with three columns, each containing ten rubber rings. The suspension system uses thirty rubber springs to ensure an adequate level of isolation from any acoustic coupling. All vertical and horizontal movements of the suspension system are controlled by large oil dampers located in the support columns. A certain degree of coupling between the base and the subchassis is necessary to cancel out unwanted vibrations from the drive system and tonearm, which are transmitted—partly as vibrations and partly as heat—through the damping fluid to the base and dissipated into the floor.
