A method and apparatus for producing low frequency sound (20 to 100 Hz) at levels of intensity above the minimum threshold of human hearing. A mechanical-electrical drive having high power capacity is coupled via a linkage to a sound radiator and is responsive to the electrical input from a sound program source. The drive is capable of large excursions at high forces which are substantially constant irrespective of the extent of excursion.
