i have this question on quality factor after reading the paper by Small, Q is defined to be a ratio of resitance to reactance for parallel circuit. But in the electrical analogous circuit of loudspeaker there is even the inductance term why don't we use the inductance in the formula? And it is measured as Qmc=wCes*R. Also when we are adding damping according to the formula resistance should increase and Qmc is supposed increases , but he writes that Qmc is less for filled enclosure then unfilled enclosures.

Thanks
