It's a number which describes mathematically the amount of damping at the speaker resonance frequency. There are 3 Qs. One associated with the mechanical damping, one with the electrical/magnetic damping and the third is the total Q taking into account both the others. When you put the speaker in a closed box you get a different set of Qs due to the change in resonance and additional box damping.
