The tolerance analysis function in LspCAD 6 makes it possible to model how component tolerances in passive components affect the SPL and the impedance of a system. Below is show the result for a passive two way system with 5% tolerance limits for all components. It is also possible to test the sensitivity against changes in Re, Cms, Mmd and Bl for a TS driver unit.
Power compression analysis can be performed in order to see how the frequency response changes when the input level increases. Below is the result of a power compression simulation for a two way passive system.
