I recently received a pre-owned pair of 2425 drivers that have both two-hole and three-hole mounts. In other words, they have a standard drilled and tapped 3-hole pattern and also a 2-hole pattern.

At first inspection, I assumed the owner had drilled and tapped the two-hole pattern but the black crinkle paint from the factory seems to outline the two-hole pattern so, I assume, these came drilled and tapped for both type mounts from the factory.

Is this correct?
