A loudspeaker and method of driving it, the loudspeaker having a panel capable of supporting bending waves, a low frequency transducer mounted to the panel for exciting bending waves in the panel at frequencies below a predetermined frequency, a high-frequency transducer mounted to the panel for exciting bending waves in the panel at frequencies above the predetermined frequency, and crossover circuitry for supplying a signal to the low-frequency transducer at frequencies below the predetermined frequency and to the high-frequency transducer for frequencies above the predetermined frequency. The predetermined frequency is substantially equal to the coincidence frequency.
