Well of course. How else could it work? But he asked about sound preference of the alignments. Who cares about qtc when eq is on board and the question is about how various Q's sound.
That's an entirely different proposition than actually changing the Qtc of the speaker by either making the cab larger or smaller, or by adding stuffing
Not different when the question is about how a particular q sounds in the presence of eq. That was the question. You don't hear qtc, you hear the final q. There may be peripheral differences regarding power compression and other thermal effects, amplifier distortion, etc, but that wasn't the question.
which alters F3, excursion, sensitivity and maximum SPL. EQ has no effect on those parameters.
F3 is certainly affected by eq, and theoretical max spl in a sealed system (what the thread was about) as frequency lowers is not altered by box size. Efficiency of course changes. No one has suggested a cheat to Hoffman's law.
