WebThese two values are always specified in pairs. Then enter the amplifier damping factor. Next, enter the nominal impedance of your loudspeaker. Finally, select your wire gauge from the pull-down selector, enter the length of the cable between the amplifier and loudspeaker, and enter the capacitance per unit length in picofarads. WebA single degree of freedom (SDOF) system, consisting of a mass-spring-damper, is often used to understand dynamic systems and their properties as shown in Figure 2. Figure 2: Mass-spring-damper single degree of freedom system. In the mass-spring-damper system: m – mass of the system [kg] c – damping of system [Ns/m] k – stiffness [N/m]
