A speaker in a closed box (including IB) is a 2nd order, high-pass system. This second-order system is COMPLETELY characterized by two parameters : Qts and Fs (strictly speaking, it's Qtc and Fc in the enclosure). These are all you need to describe the driver's frequency response, and time-domain transient response.

Qms = 2pi*Fs*Mms/Rms. Where Mms is the mass of the cone, Rms is the losses to damping. 2pi*Fs*Mms is like a measure of stored energy - but note amplitude has cancelled top and bottom. Q = 1/ (2*zeta), where zeta is the damping ratio, as seen in the governing differential equation. From this, higher zeta = more damping, higher Q = less damping.
