Klippel LPM - Thiele/Small Parameters

The LPM module determines the electrical and mechanical parameters (Thiele-Small parameters) of electro-dynamical transducers. In contrast to the LSI (that identifies the large signal parameters) it focuses on the precise measurement of the small signal domain parameters. For best accuracy, it is recommended that this test is done with a supplied Mmd, or with two driver samples one of which can be destroyed. If this is not possible, correlation between the laser method and added mass methods are used for a best approximation. The results include: full parameter set including extended inductance models, impedance curve and a full set of test conditions data confirming the accuracy of the test.
