We show that the power emitted from phase-locked soliton oscillators can exceed the upper limit given by the theory for superradiance from phase-locked point oscillators. As an experimentally relevant example, we consider two magnetically coupled long Josephson junctions, operated in single-fluxon modes. Analytical results indicate that the coupling between the two oscillators enables the phase-locked modes to localize in space thereby creating the possibility of an enhancement of the power level beyond the point-oscillator limit. Good agreement is found between analytical results and numerical simulations, and with recently published experimental data.
