[QUOTE="thch, post: 3561161, member: 562032"] the speaker wants to wobble. but can't wobble forever. Fs -- the rate at which the speaker wobbles in free air. Based on the springiness of the suspension and the moving mass. Qms -- (related to) the number of times the speaker will wobble in free air. (Q is a measure of losses in a resonating system) Also, the bandwidth over which the speaker is most efficient (in free air). Over this bandwidth, the speaker impedance will be high, reaching a maximum at Fs. Qes -- A factor representing added damping from the electrical side of things Qts -- combined damping from mechanical and electrical sources. less then Qms and Qes. Vas -- A figure for determining the springiness of the suspension. expessed as "an volume of air compressed to..." because it makes calculations easier. In concept, Vas is a measure of how much a sealed box of finite volume will affect Qms, Qes, Qts, and Fs. [/QUOTE]
