The SPL stays the same, it does not get lower.
If you only consider impedance magnitude, then yes, the amp would have to provide more current with the impedance compensation. However, if you also remember that impedance is not just about magnitude but also phase, you will see that the loudspeaker is in fact a much easier load to the amplifier with the impedance compensation applied than without it.
That's right, but in this case, you trade efficiency for easier load (in terms of electrical phase angle). If the amp have no problem with a more reactive load, then it's better to go without compensation.
If you use compensation, then the heat from the reactivity will be absorbed by the passive compensation circuit instead of the amp.

Once you decide on "8 ohms", then that's what you should be prepared for. You're talking about bonus current.
Somewhat? Right then...
Ok, the reactivity can be fully compensated, but it just moves to other aeras, and the compensation circuit lift off the reactive load from the amp.
Btw, are you using impedance correction for active setup? Just out of curiosity.

A little off topic. I am using Voltage compensation. I have plans to try impedance compensation but it will wait for a rainy day.
Why voltage compensation?
On a rainy day? This shows how important it is. 😀
(sorry, I didn't mean to offend you)
My tweeter amp has a small finite output impedance. I take pre-crossover measurements using the amp. Voila.
I do have a life 😀
