You can easily calculate the attenuation at any given frequency with a simple mathematical model considering the impedance value at frequency vs. inductance value.

And at the typical 80Hz HT xover, it is not compensated for. One would have to drop the xover point quite low for it to have zero impact.

Just as when integrating ANY drivers, there is usually no perfect linear natural transfer function. You can use parametric band on the sub line level to compensate, shift the xover frequency of the sub slightly up, modify crossover Q, etc.. Of course, since you said 'HT xover', it should be known: I consider these HT xovers as typically found in HT receivers, largely useless if one wants to have ideal integration. A device such as a Behringer DCX2496 will allow virtually any integration desired with optimal results. And if you want to get picky: realize that the room effect on the subwoofer response will alter the transfer function far more than the inductance around a 80Hz crossover point will.
