Before Poseidon joins the system, it gets measured alone.
Each one goes on the stand in our hemi-anechoic chamber, where the walls swallow the reflections. Then Selene and Poseidon get calibrated together, so the 150Hz crossover lands in time and in phase.
Two rounds of measurement before it ever meets your room.
