Conveniently, they left out how much mass first- and second-generation resonators weigh per wheel and their center of mass radius (distance) from the axis of rotation. This would be crucial to determine if cabin floor-mounted ANC speakers, mics, and a controller would/n't be cheaper to haul around than adding additional rotational inertia to the wheels. Surely, it's cheaper for manufacturing and simpler, but it doesn't necessarily translate into being the cheapest TCO solution for the buyer.
