We use the static potentials between heavy quarks derived from the classical approximation to the dual QCD field equations to calculate most of the low-lying states of the {ital c{bar c}} and {ital b{bar b}} systems. The agreement, achieved with only four parameters, two of which are roughly determined in advance, is better than 1%. The spin-orbit force cannot yet be calculated from dual QCD; if we use the Breit-Fermi form for it, all the {ital c{bar c}} and {ital b{bar b}} levels can be predicted. We also predict the masses of the lightest {ital c{bar b}} states.
