Default QMS, QTS, QES etc. for woofers in series

I will first make an assumption. The VAS is doubled for woofers wired in series. This also includes doubled voice coil resistance and inductance.

What about QMS, QTS, QES, and free air resonance impedance peak?.

The woofers are the SEAS W26FX-001.

Qts stays the same, Re is doubled and so is Zmax.

When wiring two drivers in series, you double Re, Le, Sd, Vas AND Bl. All three Q factors and Fs remain as for a single driver.
