HiAs GM suggests the BL is not the same for the 4 ohm version.
Motor strength is not BL but BL^2 / Rdc or BL / Sqr root of Rdc, the latter expressed in Newtons of force per Watt of coil dissipation.
When halves the Rdc, one gets .707 the BL for an identical strength motor.Constant displacement is the “sealed box†or spring controlled region of operation.
One can identify the presence of leaks in ones back volume if you see the impedance start to rise at very low frequencies (where in your model it goes to Rdc nearly)
