Got it. So, applying the electrical BU2 on top of the measured acoustic BU2 gives us an LR4 effective crossover.LR4 not LR2.
And usually you want to do similar measurements for the subwoofer so the (anechoic) volume of the two is equal. I discuss that in the thread i linked. You don’t want the speaker to play louder than the subwoofer or vice versa at the crossover frequency.
Restating my next steps for my own clarity, and to help this thread be a more helpful reference:
We will now do the same approach with close-mic measurements of the subwoofer to first establish its anechoic response, correct for baffle step, and use these determine what its appropriate crossover shape for the subwoofer would be. Since the subwoofer is ported, we will need to measure its port and driver then sum it as in napilopez's guide since its port is used, unlike for the desktop speakers.
